Ethereum cryptocurrency that comes second in terms of capitalization on the crypto market is traditionally seen as fast and profitable. However, over the last few weeks it's had a rough patch. Since early August, the network has had huge queues of transactions pending processing while fees have skyrocketed and surpassed the historical high.
The main issue though is that even fees of a few dollars per transfer don't help get rid of the“traffic jams”. The cause of this is numerous DeFi projects and a huge number of financial pyramids based on the Ethereum platform. Both generate excessive load on the network.
The situation is downright unpleasant, and our users might question whether the UMI network could face a similar challenge? We'd like to assure you it could not. The UMI network is by default protected against these problems — it cannot have “traffic jams”, fees or financial pyramids. But first things first.
How has the Ethereum network ground to a halt?
In its report dated August 4, Arcane Research that provides analysis within the field of cryptocurrency stated that over the previous week the daily size of transaction fees in the Ethereum network has surged up to a record high for over two and a half years. On August 3, the median value #%D0%9F%D1%80%D0%B8%D0%BC%D0%B5%D1%80_%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)of the fee amounted to $0.82, with the overall amount of transaction fees totaling $2 mln. However, it only signaled the start of real problems.
Over the next week, fees continued to grow and by August 11 the median fee value almost doubled equaling $1.57. Larry Cermak, an expert at a big analytical and news-making crypto portal The Block, wrote in his August 15 tweet that over a week the total amount of transaction fees in the Ethereum network totaled $34.5 mln, having surpassed its historical high. Meanwhile, in the Bitcoin network that is seen as too expensive the fees were almost four times lower at $9 mln.
The total fee amount paid by cryptocurrency users over a week:
  • Ethereum — $34.5 mln;
  • Bitcoin — $9 mln;
  • Monero — $2,240;
  • Tezos — $1,876;
  • Cardano — $1,615;
  • XRP — $1,138;
  • BSV — $1,102;
  • Stellar — $1,059;
  • Bitcoin Cash — $1,027;
  • UMI — $0. Let's talk about it a little later.

The existing situation shows that Ethereum is actually not as fast and profitable as commonly cited. Additionally, this could happen to almost any cryptocurrency except UMI that charges no fees whatsoever. We will tell you why.
Why have these problems emerged?
There is nothing unoriginal: the Ethereum network simply can't handle an increased load. Arcane Research analysts consider that a principal cause of this situation is the constantly increasing number of the DeFi ecosystem projects built on the Ethereum blockchain. Their number is growing all the time which causes the overload of the network. As of August 12, the total amount of funds in DeFi applications reached $4.3 billion which is 19.5% higher than that in the past week. At the time of writing this article, the amount surged to $6.21 billion. You can see the current data here. What is the most unpleasant about DeFi protocols is that a lot of them are scam projects.
Which is not the worst part though. There is also another factor that significantly slows down the Ethereum network. There are a lot of pyramid-like projects that are built on the EOS platform and use smart contracts. One of them is SmartWay Forsage, which regularly overloads the network with a large number of transactions, causes traffic jams, and, consequently, leads to increased fees (keep in mind that Ethereum miners choose transactions with a higher commission). Vitalik Buterin, the co-founder of Ethereum, revealed his disapproval of the SmartWay Forsage methodology and asked them to "leave and not pollute Ethereum ecology in the future". However, the project is slow to do this — it continues to deceive users.
This is only the tip of the iceberg of scam projects which abounds on the EOS network –– they continually emerge, work for a while, then go down as scams and are replaced with new ones. This never-ending stream of "investment projects" based on the Ponzi scheme overloads the system. This is the reason why Adam Back, a pioneer of the crypto industry and founder of the technology company Blockstream, equated Ethereum with such infamous projects as Onecoin and Bitconnect. Adam Back's solid dig at Ethereum became the subject of much debate among crypto enthusiasts.
Of course, it all doesn't mean that Ethereum is a bad cryptocurrency. On the contrary, it has a lot of advantages over other coins. But all that has happened exposes Ethereum's faults which must be eliminated. The problem is that they may not be fixable. It is far from certain that the developers will be able to get rid of all the defects as the system has huge scalability problems.
The crypto community has to admit that Ethereum, like other first-generation cryptocurrencies, has issues with capacity, fees, and scalability and is gradually becoming obsolete.
2020 is the time for young innovative cryptocurrencies such as UMI.
UMI is the flagship of new-generation cryptocurrencies.
In real fact, any cryptocurrency could face it. Each cryptocurrency charges fees which typically surge when the network is overloaded or the price is going up. Everyone will remember 2017 when in line with price growth and the network's overload Bitcoin transaction fee reached a high of around $40.
But when it comes to UMI, it works the other way round. The UMI network's advantages are high capacity, no fees, and scaling possibilities. It uses the best and fastest crypto industry solutions and excludes all inefficient methods by default. Smart optimization in combination with the Proof-of-Authority technology operating on the master node basis enables almost instant payments.
At the stage of network testing, an incredibly high capacity was achieved:
  • up to 4,369 transactions per second;
  • up to 262,140 transactions per minute;
  • up to 15,728,400 transactions per hour;
  • up to 377,481,600 transactions per day.
Ethereum processes about 20 transactions per second. It means that the UMI network can process transactions that Ethereum processes over a year in 1 to 5 days — and with no fees.

The UMI network can process transactions that Ethereum processes over a year in a few days and with no fees. More details
What is more important is that less than 0.001% of the network's overall potential is used now. The UMI network has a lot of reserve capacity and can handle hundreds of thousands of times heavier load. Moreover, with scaling possibilities, UMI can keep up with the times. The UMI code ensures the safe introduction of any upgrades — the network can be easily modified and scaled with cutting edge technology solutions. In other words, traffic jams will never pose a problem for us. UMI will instantly process all transactions, with no fees. Always.

A real-time speedometer displays the number of transactions processed by the UMI network per second. Link
Additionally, unlike Ethereum and other cryptocurrencies, the UMI's staking smart contract prevents possibilities of any pyramid schemes, meaning eliminates their negative influence. Our staking is completely safe and secured against scammers. Read more about this in our article. Any UMI staking structure could work forever. In other words, you can multiply your coins at a rate of up to 40% per month for an indefinitely long period of time.
UMI doesn't inherit the disadvantages of the first-generation cryptocurrencies. This is an innovative, carefully designed network based on state-of-the-art technologies. UMI is an ambitious step toward the future. And we're making it together right now!
Sincerely yours, UMI team

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
https://preview.redd.it/1kfccgps2pg51.png?width=832&format=png&auto=webp&s=bf6c7f614c600826006bc2bf8a6026292c3b328c
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.

https://preview.redd.it/pme9tcd62pg51.png?width=832&format=png&auto=webp&s=049f899d2a5ee3ce64007d5cc0ae3ed6167c2b3a
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:

https://preview.redd.it/nld8k8gb2pg51.jpg?width=926&format=pjpg&auto=webp&s=8c2435c993cf86b2bf6b0c4d2a1935708734de97
The release plan of data provider incentive is as follows:

https://preview.redd.it/kgia5n6d2pg51.jpg?width=982&format=pjpg&auto=webp&s=ad1bfe7796fdaec58f3caede2f2a2083c0a07724
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.

However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

TOR

Starting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies.

https://i.redd.it/kn5waeskttx41.gif
Tor is a powerful privacy feature for those who own large assets or live in places where the Internet is heavily censored.
Tor technology provides protection against traffic analysis mechanisms that compromise not only Internet privacy, but also the confidentiality of trade secrets, business contacts, and communications in General.
When you enable TOR settings, all outgoing traffic from the wallet will be encrypted and routed through an anonymous network of servers, periodically forming a chain through the Tor network, which uses multi-level encryption, effectively hiding any information about the sender: location, IP address, and other data.
This means that if your provider blocks the connection, you can rest easy — after all, by running this function, you will get an encrypted connection to the network without restrictions.

https://preview.redd.it/w9y3ax4mttx41.png?width=960&format=png&auto=webp&s=972e375fc26d479e8b8d2999f7659ec332e2af55
In TOR mode, the wallet may work noticeably slower and in some cases, there may be problems with the network, due to encryption, some blockchain browsers may temporarily not work. However, TOR encryption is very important when Internet providers completely block traffic and switching to this mode, you get complete freedom and no blocks for transactions.

Confidentiality of transactions (the Blockchain transaction)

The wallet can change the model of a standard transaction, mixing inputs and outputs, making it difficult to identify certain cryptocurrencies. In the current update, you can select one of several modes for the transaction privacy level: deterministic lexicographic sorting or shuffle mode.

Mode: Lexicographic indexing

Implemented deterministic lexicographic sorting using hashes of previous transactions and output indexes for sorting transaction input data, as well as values and scriptPubKeys for sorting transaction output data;
We understand that information must remain confidential not only in the interests of consumers but also in higher orders, financial systems must be kept secret to prevent fraud. One way to address these privacy shortcomings is to randomize the order of inputs and outputs.
Lexicographic ordering is a comparison algorithm used to sort two sets based on their Cartesian order within their common superset. Lexicographic order is also often referred to as alphabetical order or dictionary order. The hashes of previous transactions (in reverse byte order) are sorted in ascending order, lexicographically.
In the case of two matching transaction hashes, the corresponding previous output indexes will be compared by their integer value in ascending order. If the previous output indexes match, the input data is considered equal.

Shuffle Mode: mixing (random indexing)

To learn more about how “shuffle mode” works, we will first analyze the mechanisms using the example of a classic transaction. Current balance Of your wallet: 100 TKEY, coins are stored at different addresses:
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
Addresses in the blockchain are identifiers that you use to send cryptocurrency to another person or to receive digital currency.
In a classic transaction, if you need to send, for example, 19 TKEY — 100 TKEY will be sent to the network for “melting” coins, 19 TKEY will be sent to the Recipient, and ~80.9 TKEY will return to the newly generated address for “change” in your wallet.

https://preview.redd.it/x595qwdottx41.png?width=806&format=png&auto=webp&s=d9c2ae5620a3410ed83f7e16c018165c8ab35844
In the blockchain explorer, you will see the transaction amount in the amount of 100 TKEY, where 80.99999679 TKEY is your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee. Thus, in the blockchain search engine, most of your balance is shown in the transaction.

How does the shuffle mode work?

Let’s look at a similar example: you have 100 TKEY on your balance, and you need to send 19 TKEY.
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
You send 19 TKEY, the system analyzes all your addresses and balances on them and selects the most suitable ones for the transaction. To send 19 TKEY, the miners will be given coins with x2. Addresses, for a total of 20 TKEY. Of these, 19 TKEY will be sent to the recipient, and 0.99999679 TKEY will be returned to Your new address as change minus the transaction fee.

https://preview.redd.it/doxmqffqttx41.png?width=1400&format=png&auto=webp&s=5c99ec41363fe50cd651dc0acab05e175416006a
In the blockchain explorer, you will see the transaction amount in the amount of 20 TKEY, where 0.99999679 TKEY is Your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee.
The shuffle mode has a cumulative effect. with each new transaction, delivery Addresses will be created and the selection of debit addresses/s that are most suitable for the transaction will change. Thus, if you store 1,000,000 TKEY in your wallet and want to send 1 TKEY to the recipient, the transaction amount will not display most of your balance but will select 1 or more addresses for the transaction.

Selecting the recovery method for each digital currency (Blockchain restore)

Now you can choose the recovery method for each currency: API + Blockchain or blockchain.
Note: This is not a syncing process, but rather the choice of a recovery method for your wallet. Syncing takes place with the blockchain — regardless of the method you choose.
https://preview.redd.it/gxsssuxrttx41.png?width=1080&format=png&auto=webp&s=cd9fe383618dda0e990e86485652ff95652a8481

What are the differences between recovery methods?

API + Blockchain

In order not to load the entire history of the blockchain, i.e. block and transaction headers, the API helps you quickly get point information about previous transactions. For example, If your transactions are located in block 67325 and block 71775, the API will indicate to the node the necessary points for restoring Your balance, which will speed up the “recovery” process.
As soon as the information is received, communication with the peers takes place and synchronization begins from the control point, then from this moment, all subsequent block loading is carried out through the blockchain. This method allows you to quickly restore Your existing wallet.
‘’+’’ Speed.
‘’-’’ The API server may fail.

Blockchain

This method loads all block headers (block headers + Merkle) starting from the BIP44 checkpoint and manually validates transactions.
‘’+’’ It always works and is decentralized. ‘’-’’ Loading the entire blockchain may take a long time.

Why do I need to switch the recovery method?

If when creating a wallet or restoring it, a notification (!) lights up in red near the selected cryptocurrency, then most likely the API has failed, so go to SettingsSecurity CenterPrivacyBlockchain Restore — switch to Blockchain. Syncing will be successful.

Selecting the address format

You can choose the address format not only for Bitcoin but also for Litecoin. Legacy, SegWit, Native SegWit. Go to SettingsManage WalletsAddress Format.

Working at the code level

Enhanced validation of transactions and blocks in the network

Due to the increased complexity in the Tkeycoin network, we have implemented enhanced validation of the tkeycoin consensus algorithm, and this algorithm is also available for other cryptocurrencies.

What is the advantage of the enhanced validation algorithm for the user

First, the name itself speaks for itself — it increases the security of the network, and second, by implementing the function — we have accelerated the work of the TkeySpace blockchain node, the application consumes even fewer resources than before.
High complexity is converted to 3 bytes, which ensures fast code processing and the least resource consumption on your device.

Synchronization

The synchronization process has been upgraded. Node addresses are added to the local storage, and instant synchronization with nodes occurs when you log in again.

Checking for double-spending

TkeySpace eliminates “double-spending” in blockchains, which is very valuable in the Bitcoin and Litecoin networks.
For example, using another application, you may be sent a fake transaction, and the funds will eventually disappear from the network and your wallet because this feature is almost absent in most applications.
Using TkeySpace — you are 100% sure that your funds are safe and protected from fraudulent transactions in the form of “fake” transactions.

The bloom filter to check for nodes

All nodes are checked through the bloom filter. This allows you to exclude fraudulent nodes that try to connect to the network as real nodes of a particular blockchain.
In practice, this verification is not available in applications, Tkeycoin — decided to follow a new trend and change the stereotypes, so new features such as node verification using the bloom filter and double-spending verification are a kind of innovation in applications that work with cryptocurrencies.

Updating the Binance and Ethereum libraries

Updated Binance and Ethereum libraries for interaction with the TOR network.

Interface

Function — to hide the balance

This function allows you to hide the entire balance from the main screen.

Advanced currency charts and charts without authentication

Detailed market statistics are available, including volumes, both for 1 day and several years. Select the period of interest: 1 day, 7 days, 1 month, 3 months, 6 months, 1 year, 2 years.
In version 1.3.0, you can access charts without authentication. You can monitor the cryptocurrency exchange rate without even logging in to the app. If you have a pin code for logging in, when you open the app, swipe to the left and you will see a list of currencies.

Blockchain Explorer for Tkeycoin

Transaction verification for Tkeycoin is now available directly in the app.

Independent Commission entry for Bitcoin

Taking into account the large volume of the Bitcoin network, we have implemented independent Commission entry — you can specify any Commission amount.
For other currencies, smart Commission calculation is enabled based on data from the network. The network independently regulates the most profitable Commission for the sender.

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

https://preview.redd.it/5vpheheqmba31.png?width=770&format=png&auto=webp&s=ec3c58fb7fafe10a512dbb131ecef6e841e6721c

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.
You can find out more about Ethermint here and here

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

BitMax.io & Lambda Joint AMA

BitMax.io & Lambda Joint AMA
George Cao :Let’s welcome lambda team . Xiaoyang and Lucy
Lambda: Hello friends from BitMax ~~ I am Lucy Wang, Co-founder and CMO of Lambda. I am very happy to e-meet with you here and thx for George's invitation. I on behalf of Lambda wish all of you a merry Christmas and prosperous new year in 2019
George Cao: Great. I am a bit surprised to see a big volume day yesterday Christmas. Seems our users didn’t take a break even on holidays :)
Lambda: I'd like to take this opportunity to introduce myself first, I have over 14 years of progressive career development with global leading enterprise software / service organizations as well as VC-backed start-up ventures, including HP, Oracle, and SAP. Before Lambda I was CMO/GM at two enterprise SaaS start ups in China backed by top VCs.
And my partner Mr. He Xiaoyang, who is the founder of Lambda, he is a well-known expert in infrastructure and open source software in China. Prior to Lambda, he was the co-founder of OneAPM, a fast-growing infrastructure software focusing on ITOM (IT operation management) in China. OneAPM is known as the “New Relic or AppDynamics of China” and the company has received strong VC backing from Matrix Partners, Chengwei Capital, and Qiming Venture. Prior to his entrepreneur experiences, Mr. HE worked at BEA as a R&D software engineer. In addition, Mr. HE is also a blogger with strong following in China and some of his articles have been published by major media such as Forbes China, 36Kr, Sina, etc.
Lambda idea was born at the end of year 2017 and the product development started from the beginning of 2018. Now let me talk about Lambda idea and what we do
Lambda, is the leading decentralized infrastructure project providing secure, reliable, and infinitely scalable decentralized storage network that enables data storage, data integrity check, security verification, and marketplace for storage-related services on the Lambda Chain Consensus Network.
In recent years, there have been frequent data leakage problems in major Internet platforms at home and abroad, and even business giants such as Facebook and Marriott have not been spared. Returning the value of data to data owners is an inevitable trend in line with human pursuit of freedom. The block-chain technology with P2P features provides an opportunity for this, and this area will be highly valued by the industry in the next few years. Lambda is the only provider of block-chain storage infrastructure projects in China. It is sometimes referred as “File-coin of China”or “File-coin 2.0”.our vision is to return the value of data to the data owner, with this vision in mind, our mission is to promote the decentralization of the Internet, with the goal of creating a storage infrastructure for the next generation of block-chain.
After the Lambda project launch in early 2018, it has received strong support by well-known strategic and financial investors including Bitmain, Viking Capital, FBG Capital, Bluehills, Zhen Fund, FunCity Capital, Ceyuan Digital Fund, BlockVC, INBlockChain, DATA Foundation, Bitcoin World, Reflextion Capital, etc. To date, Lambda has received investment funding in excess of $10M.

n all the existing decentralized storage projects that are aiming to give a solution to this problem worldwide, Lambda is the first ever to announce its LPDP ( Lambda Provable Data Possession )
George Cao: I see we share several investors in common, So 2019 q1-q2 will be a big milestone for lambda
Lambda: Provable Data Possession (PDP) and Proofs of Retrievability (POR) are critical to efficient decentralized data storage and its implementation, which is the essential difference between centralized network projects and real decentralized storage. Prior to Inter-planetary
File System (IPFS), Lambda launched its minimum viable product (MVP) of core functions in the third quarter of 2018, and has been continuously upgrading and optimizing this in block-chains in a multi-role environment.
File-coin is our main competitor, here is a chart shows the progress comparison FYI

https://preview.redd.it/ewmyh9tqs2721.png?width=1267&format=png&auto=webp&s=cddc52a6d613196f6c0cbf870da42a5b82a8aaa6
For those who have interest to know more about Lambda's technical innovations, they can be find in our keep updating FAQ document posted on Medium, and I copied her FYI
1.Innovatively designed the Validator role which provides verification service for storage proof and the Validator replaces storage miner as the full-time storage proof result verifier, this greatly improves the performance of the storage and retrieval system.
2.In response to the limitations of the PDP algorithm, Lambda innovatively created a consensus network on the block-chain and used the validators role to replace the "TPA" in the PDP algorithm.
3.Innovatively modified the PDP algorithm from synchronous to asynchronous communication, which greatly reduces the communication traffic for Challenge in the system. Use of chain data as a random seed for storage miners to issue Challenge themselves addresses the randomness of TPA challenges.
4.Innovatively upgraded the PDP algorithm from periodic verification to a verification set generated by the miners to submit the verification result at one time, and fully realize the Proof-Of-Space-Time verification.
on top of all the technical, Lambda creates a consensus network where data can be stored, storage space can be rented on the basis of a marketplace built on block-chain.
In the Marketplace, the transaction process is: storage miners pledge hard disk sectors to the consensus network, and place orders and sell their own storage space in the Marketplace; storage users initiate purchase requests, complete the matching of storage requests through the Marketplace, and store data in the space of the storage miners.
Different from other block-chain applications, Lambda is a storage mining project, we have miners mine on Lambda network. Earn LAMB tokens by contributing on the network, and users who have data storing requirements pay Lamb tokens to purchase services accordingly.
The price of Lamb token not only rely on the exchanges but also supported by our miners who are doing works on the network.
There are four roles in the Lambda mining network: storage miners (providers of storage space), verification miners (ensuring the integrity and security of data and packaging transactions), retrieval miners (providing download bandwidth), and users (storage buyers). 1024 verification miners promoted from storage miners constitute the Lambda-chain consensus network. So you will see three types of miners serve our users from all over the world.
The key milestones we are looking at is the launch of test-net, where miners can start mining and earn testing Lamb tokens, the date will be around end of Jan. 2019 and main network will go live in Q2, 2019, most likely in Apr.
Regarding our partnership, In the academic field, we have established a strategic partnership with Beijing Institute of Technology (BIT), which is well known in China for its engineering and computer science research programs, to conduct research into centralized storage.
In the commercial field, Lambda has established a strategic collaboration with IOST, a well-known public blockchain project, and Perlin, a super computing platform, and started to conduct pilot projects for decentralized application (DAPP) companies such as DATA and BCV. Lambda also has close ties to many leading Internet data centers (IDCs) in China. They join the Lambda network as miners and take advantage of their surplus server capacity to engage in the Lambda network ecology.
Q: Will the rest of the code be open sourced? If so when ?
Lambda: we have released the codes of core function module, the test net codes will be released gradually in Jan. pls stay tuned with our official github
Q: What can Lamb tokens be used for?
Lambda: Lambs are tokens in the Lambda ecosystem, which are mainly used in the following scenarios:
A. Users of services in the Lambda ecosystem have to pay with Lambda tokens.
B. Providers of storage services in the system have to pledge a certain number of tokens.
C. Verification nodes in the system have to pledge a certain number of tokens.
D. Verification nodes can obtain a certain number of tokens as accounting rewards.
E. Storage nodes get a certain number of tokens based on their storage capacity and their service level agreements (SLAs).
F. Other roles in the Lambda ecosystem can also obtain a certain number of tokens based on their contributions.
Q: What more incentives does miner gets to mine or rent storage on Lambda?
Lambda: every miner stars from storage miner on Lambda network, they get paid by providing storage space, when their business getting bigger, system will select the top 1024 storage miners and promote them to validator, who will get block generation rewards from system.
Q: how are the 1024 miners selected? Doesn't this become more centralised?
Lambda: we did a survey to the Chinese miners, they mainly fall into two groups, either are waiting FileCoin to go live with purchased mining machine idle at home or they are doing hard drive or graphic cards mining, which has a high requirement to the hardware standard. To mine on Lambda, you need a mining machine ( computer ) that has big storage space ( because the bigger the higher probability you'll be promoted to be a validator ) and the connection to the internet
Q: How much is initial supply?
Lambda: Lambda did two rounds of fund raising, private investors have a lock up terms of 2+4+4 meaning the first 20% of tokens will only be released 2 months listing on exchange. so on the day one listing till 2 months there will be only around 0.5% initial circulation, and after 2 months, 5% in total. in addition to that, as we are recruiting miners to join our network, actually ppl have been in a situation where they can't wait to mine on our testnet. with the mining mechanism we have, miners need to buy Lamb token to get their mining work started, because a certain amount of pledge need to be made
Q: What partnership will lambda and bitmax have in the future?
Lambda: We value the way BitMax doing things and care about projects, we feel like we found the right exchange to be listed, in particular an initial listing. we will work with BitMax and do some joint campaigns to boost the community
George: We have great chemistry with lambda team.
Q: And are you still primary list in there, I heard the list was delay? Is it related to Huobi?
Lambda: you are right, it is related to Huobi, but one thing you can be assured of is that our initial listing on BitMax wont change, but most likely a joint listing with Huobi.
Q: what about the time of primary list?
Lambda: we will primarily list very soon, we are targeting end of this week, now we are in the middle of some technical integration with Huobi
George: We can assure everyone that our team will do our best to protect our investors and serve our listing projects. The promise does not change whether or not if we co-list with huobi.
Q: We get reward to mine ? Any incentive? For testnet
Lambda: Yes, you have two ways obtain Lamb tokens, buy from exchange and earn more from mining, but firstly you have to buy Lamb on BitMax haha. Are you asking the reward from testnet by mining on it? yes, you will get test Lamb token, and they can be redeemed to Lamb token with a ratio that will be specified shortly. on Lambda official website www.lambda.im, we have whitepaper, besides that we also have economic whitepaper to explain how the lambda economic system runs, on Dec. 28 we will launch our yellow paper where we will demonstrate the detailed technical realization and all the parameter setting for mining on Lambda
Q: What are the implications if a miners rig goes offline or they decide to stop?
Lambda: If miners rig goes off, they will not get the reward from the corresponding generated block, if they do cheating there will be punishment from the system, and if they decide to quit, the pledge will be returned
Q: Lambda planning to have own FS?
Lambda: Yes, FS and consensus network is separate. validators and marketplace are on the consensus network, while Files are in the File System.
Q: Is Lambda GDPR friendly?
Lambda: yes, we are
Q: Hi can u explain what’s the requirements of decentralized data . Do You think big companies will like to use lambda services .... or it’s for medium level enterprises as big companies will go for their in house system with their reliable nodes ...
Lambda: this is a good question, from I seeing it, ppl call out the protection of privacy, it is a trend and it takes steps. Lambda has two big groups of prospects users, one is DAPPs, another is the general industries such as big data, AI, IoT, Games, Financial, etc, as long as they need massive data storage demand, Lambda has the opportunity, data storage is expensive, especially when we are talking about big data, a lot of companies will value the cost in this area very much. currently we have lighthouse customer like DATA, BCV, VVshare, in the very near future, a game that is developed by Lambda team will also go live on Lambda network. from the BD perspective, Lambda will create a satellite network ( you can take it as channel network ) to bring us customers, we have a few reaching out to us already
Q: Why suddenly launched on Huobi
George Cao: I believe lambda team has its own consideration. Projects esp in bear market are facing pressures from different parties. Investors users exchanges. Not everything is under projects control. What we can do as an exchange is to stand by our partners and fully support them down the road
Lambda: thx for the answer
Q: I think you have made a great choice working with bitmax. Bitmax have really helped push new
coins and their site in general with good PR, marketing and reward/airdrop promotions
Lambda: strongly agree with you
Q: GDPR has taken over the EU and the UK so that is very important
Lambda: you are right, so we see to be GDPR friendly, which is one of our differentiator from FileCoin
Q: Being GDPR friendly , European market is a go for lambda
Lambda: I have this plan to develop European market by having a Raspberry program, it is still in planning.
George Cao: Let’s take a last question and move to lambda community:) And as usual we will pick 3 best questions. We will send out 1000 800 and 500 btmx. @lambda do you want to pick 3 questions ?
Q: Recent partnerships are interesting , can you tell us about coming q1 2019 both in terms of technical and marketing developments ?
Lambda: from Marketing side, we are focusing on Chinese miners community and potential European market ( like I said still in construction ) Korean market is another, and US market to go along our compliance path, Lambda has been strictly abide by the regulations. from technical side, the most important task we are targeting is the main network launch as planned
George Cao: Thanks everyone for your time. It’s a great ama as usual. We do have the best community. We will pick 3 winners and we will announce here after we finish ama in lambda community
Lambda: thank you all for your time to participate the AMA, I had a great time with you, see you friends and have a nice day.
George Cao: Hello everyone, Merry Christmas:)
Lambda: Hello Lambdos. Today we have George, the founder of BitMax to join us for the AMA. Let's give him a warm welcome to do a introduction of BitMax
George Cao: I am George Cao, founder of bitmax. I am happy to take the opportunity to talk to everyone here. Thanks to the lambda team. Let me start with a brief introduction about us.
Bitmax.io (btmx.io) is an exchange founded by a group of Wall Street veterans. Unlike most projects, we are kinda of old :) core team are in their 30ish - 50ish. The 10 founding member have combined of 150 years of Wall st experience. I have 10+ yrs of high frequency trading experience therefore I know the trading system well. That’s why our match engine can handle 400k tps per second vs huobi 1000 tps. We want to build an exchange that is transparent, robust, and efficient. While our system is the best in class, we offer the lowest trading fees. We believe the current high commission will not sustain and we will see consolidating of the exchanges with better depth and liquidity and lower commission. We are happy to partner with lambda, one of the best projects in 2018. We are committed to serve the project and the community. Alright, I am ready to take questions. Anything you can ask, as tough as you want :)
Q: Haha nice platform.
George Cao: Thanks. We are young as a platform but we are working to deliver the best
Q: I see reverse mining is new , I used many other mining exchange but all have normal mining . How does reverse mining works?
George Cao: Reverse mining is an innovative approach that helps the exchange and the project in several ways. 1) the concept of reverse mining is by providing liquidity to the exchange, you get a rebate and deduct out tokens from your account of the same valued. You can think of a otc sell our. 2) the benefit is it removes lots of sell pressure from the secondary market. And provides a strong support for the token price. 3) it introduces lots of liquidity to the exchange and benefits all traders
Q: The BTMX used in reverse mining are locked forever?
George Cao: Yes so the total number of tokens are always reducing your
Q: I've really been enjoying using the bitmax exchange so far especially with the low fees and data usage rewards. Does the exchange plan to bring in a shorting function in the near future?
George Cao: Yes we will have margin and futures trading
Q: It was supposed to December right ?
George Cao: We postponed our margin to Jan. The reason is we want to be more careful on protecting margin call protections.
Q: Margin trading and futures is important for BTMX price to drive up
George Cao: Totally agree
Q: Does BitMax have any activities on New Year's Day?
George: We do have multiple promotional events. Including but not limited to airdrops. Please visit our website and stay tuned
Q: I saw the whitepaper of bitmax, can you talk more about your dividends the formula is really hard for me ?
George Cao: Sure 80% of our commission goes to our fee pool. 1/180 of the total pool will be distributed daily. As long as you are a token holder, the current rate we pay is over 100% annually
Q: Oh I see, so the dividends will be smooth, great idea.
George Cao: Yes unlike other mining exchanges have huge volatility on div we smooth our curve
Q: I've also heard there is a mobile app in the works, is this likely to be released in the near future?
George Cao: Almost done. Beta version is in testing
Q: What about the north American, will it be available in the future?
George Cao: We more cleared our legal path for fiat trading in us. Q1 2019 we will launch in the us
Q: Great news I think this will bring a big volume.
George Cao: Yes agree. Our team is excited as well
Q: With promotional Airdrops that require a certain amount of the BTMX token to be held such as The lamb one that has taken place on the exchange this week. Are tokens that are locked for data usage or in cards taken into account when balance screenshots are taken?
George Cao: Yes we will take that into account
Q: When will be the private sale tokens be released ?
George Cao: As soon as we mined 90m we will start to release
Q: So let me get this right .. you give us FREE BTC and ltc and even Lambda EVERYDAY if we hold BTMX and agree to share our data
George Cao: Free usdt btc eth
Q: Wow. In a bear market, Free btc is the best thing ever
George Cao: We share revenue with our users, 90% is usdt. Not sure if you like it:)
Q: also consider adding coins like ADA and few from top 30. People need more coins
George Cao: We are adding stellar and zcash soon
Q: I heard they are insured Unless we give password to someone hehe
George Cao: Yes we are using custodian service
Q: George are our funds SAFU with you? Exchange insurance? I would say it is With the industry giants backing this exchange
George Cao: Sequoia matrix bitmain fbg dhvc are our equity investors
Q: What’s to stop People dumping BTMX token after free btc Or stop capital investor dumping on retailer
George Cao: They get it every day. Why would they dump? All equity investors can not sell on secondary market. They can only to reverse mining
Q: Will margin allow reverse mining instead of normal mining?
George Cao: Not initially
Q: People do irrational things when btc moves Or whales dumping, I heard there was a lock up token or something. To stop this
George Cao: We required lock our tokens to get rewards. You can request to unlock at anytime but it takes 24 hours to process
Q: Binance is developing DEX any plans for BitMax ?
George Cao: Not anytime soon we have a looong to do:)
Q: It's good you have dex in mind , with improved scalability in future maybe bitmax can build good dex
George Cao: Agree
Q: Retail investors are important , George knows it haha
George Cao: We care most of retails
Q: It would help if they also burned or locked tokens up
George Cao: Yes we permanently locked
Q: Seems you have everything thought of.. but how about moving to Malta?
George Cao: We priority US. Once us is clear pretty much everywhere is clear
Q: Doesn’t any exchange cover US right now?
George Cao: Coinbase but they have 0 international coverage and 0 client service
Q: What sort of systems are in place for abnormal/suspicious activity on the exchange?
George Cao: We prohibit self trading. For unusual trading behavior we ban the account and as for explain in the first violation. For continued violations we permanently ban the account
Q: can we get a glimpse of mobile application ?
George Cao: There is a beta version you can use but we are keep improving
Q: What are the precautions taken to prevent wash trading ?
George Cao: We have pre trade and post trade checksums. E.g we don’t just scan one account. We check or related account
Q: Will market orders and stop-loss orders be available in the future?
George Cao: Yes we are working on it
Q: what do you think of lambda project and community
George Cao: Lambda is definitely one of the best projects this year. We have been working with lambda for months and have lots of respect ion for the team. Community is also great very well organized. I didn’t talk much but I joined lambda tele group for a while. Great interaction
Q: So the trading starts at 8 pm ETC?
George Cao: It’s postponed. Please stay tuned for announcements
Lambda: We will make announcement giving out time and new date.
Q: when please? It's also more professional to be able to give dates and respect them
Lambda Cao: we are working hard and aiming the date of Dec. 29, pls stay tuned, thank you
George: Unfortunately bitmax and lambda don’t have 100% control of the date and time. Huobi is holding the ball
Lambda: The listing dates have been postponed and we don't want to give out a random date. I request you to have patience and wait for official announcement
Lambda: we will try everything to protect retails interest
Q: Can’t let houbi just arrive late to the party?
Lambda: in the long run we may need Huobi to help us better protect us all
George Cao: We trust lambda team can make the best decision for all investors
Q: Have you been busy with listing recently? Anything else?
George Cao: We have been working 24 hours a day including Chris eve :) Listing and app and margin and lots of new improvements
Q: Why would we need huobi with bitmax on our side.
George Cao: Trust me we are as upset. However as an exchange our mission is to serve projects and investors. Please join us in fully supporting any decision lambda team made. We have 100% confidence in lambda
Q: Are you familiar with the REKTbot and SYSTEM OVERLOAD problems at bitmex
George Cao: Yes but still bitmex is the best place to trade future compare with okex
Q: Slap that Hayes fool when bitmax start margin and futures..
George Cao: Haha i don’t want to declare war with them. Let’s be a bit patient :)
Q: Could bitmax handle That volume and not system overload
George Cao: We are 100% confident
George Cao: Alright i have to run for another meeting. It’s been a great ama. Thanks everyone. For any trading related questions please contact our client support. We promise to get in touch in 5 mins 7/24. Thank you all!
Lambda: thank you for participation, have a nice day!

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.

see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.

Ethermint

Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.

IBC
IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/twjzlc8hiba31.png?width=1100&format=png&auto=webp&s=2e546142573b61af031e27dac83ddca675a4b693
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344

Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

PortBitX.COM White Paper

White Paper


We are a free society united by the basic idea of ​​freedom and justice, separated from geographical, religious, ethnic and gender prejudices, we reaffirm this document, and we promise to protect freedom and benefit people always and everywhere.

PortBitX Project

The PORTBITX project team creates a service whose main idea is to provide a mobile and convenient system where users and cryptocurrency owners can receive a wide range of services.

1 The essence of the project

The project team asks you to support the creation of a high-tech, simple, convenient and honest ecosystem for people who need to protect their rights and freedoms and use the right to be anonymous and financially independent.
The mission of the project is to create a service for storing and exchanging cryptocurrency assets, and also to become a tool allowing to conduct trading operations regardless of geographic location or language skills.
Advantages of the project:

2 State of affairs

Owing to ignorance or low awareness of people about the nature of cryptocurrency assets, cryptoindustry is mythologized in modern society. This applies to both ordinary people and officials in authority.
As a rule, in the minds of people there is more confidence in traditional financial instruments than in technology during their development, for example blockchain (the inability to change the information block / blockchain chain).History knows many examples when the governments of different countries, guided by the interests of their citizens, inadvertently led to the decline of advanced civil initiatives. This time is a period of complex formation of crypto-economics and state relations, which is still in the making.
The project that we present to your attention has no borders between countries and peoples. And we, a group of enthusiasts, would very much like to cooperate with large government organizations. But, to our deep regret, the states currently at the stage of formation of their cryptocurrency policies make mistakes that negatively affect the crypto community.
The market of cryptocurrency assets, which has a ten-year history of development, is very sensitive to various statements by officials. However, unqualified criticism cannot withstand the global trend. And no one can stop the future.
With all the desire, time does not stand still, technologies themselves continue to evolve, new technologies, new projects, new views that can be upgraded in the distant future, as well as processes of government and regulation themselves, to introduce innovative elements into them. We do not expect the distant future, and many tools are available now. And we have something to offer you.
This is especially relevant against the backdrop of the upcoming global financial crisis, with the inevitable decline in trust in state financial institutions; cryptocurrency have high chances of becoming more popular in the absence of other technological alternatives.
As we noted earlier, there is a lack of awareness among people about Blockchain technology and cryptocurrencies. These technologies are extremely undervalued, since there is much more benefit in them than one can imagine.
In the cryptocurrency assets industry itself, there are fraudsters at this time who are trying to steal or fraudulently get your money.
At the same time, there are many honest crypto projects that can not be realized due to stereotypes of perception of them as fraudulent. Objectively, they could be judged by their work and projects that have been successfully implemented. In principle, it is necessary to be cautious in terms of investing in any projects, even if they are guaranteed by reputable people or companies. No reputable person or company can match the level of guarantee and security of your assets, as in the Bitcoin blockchain.In any case, the decision to invest is yours, not imposed by restrictions, and the responsibility lies with you.
According to Road Map, we intend to fulfill all the terms of the agreement with our participants.
We do not promise you a high yield of our tokens, we put all our experience into the overall welfare of the project and each user. There will be no delisting on the service until the community votes for the opposite.
Our risk is collective. We urge you to make an adequate and balanced choice, instead of imposing any other opinion on you. We are not supporters of aggressive marketing.
There are many cryptocurrency assets and it’s difficult for a regular user to store and exchange them, as well as use them in everyday life.

3 Disadvantages:

These are problems that affect users and cryptocurrency in general.

4 Solution

The PORTBITX project guarantees compliance with all of its obligations and user rights.
We integrate community communications into our PORTBITX service.
Users are offered the following functions:

5 Competitors

Direct market competitors are all decentralized and centralized services related to the purchase or sale of cryptoactive assets, as well as services that provide storage services on a cold or hot crypto wallet.
More than 16 thousand services and more than 2 thousand types of cryptocurrency assets.
We have the opportunity to offer our clients a reliable and open service for the storage and exchange of cryptocurrency assets.
The main competitors are such large cryptocurrency exchanges like Binance, Bitfinix, Bitrix, etc. These multibillion-dollar projects that can affect the entire market and regulate pricing also have millions of crypto communities.
This position is deserved by their work. There are, of course, disadvantages associated with the opacity of their activities, unlike us, but in general they play an important role in the cryptoindustry. Their trading volumes are impressive and inspiring, their mistakes lead to sharp price fluctuations in the crypto market.
There are still crypto exchange. In comparison with the leaders, they are significantly inferior in the volume and number of users. These exchanges include the bulk of all crypto exchanges on the market.
There are also exchange services on the market that allow you to exchange fiat money for cryptocurrency assets. Most often the commission is quite expensive. For example, they can range from 1% to 20%. Such a high commission can be explained by the fact that the locations where buyers and sellers are located have government restrictions or are prohibited.
In addition to all of the above, there are closed groups in social networks or instant messengers. There, people discuss and agree on the price and method of payment. Commissions are often not high from 0% to 5%, but one should not hope that such operations can be safe, since personal meetings are always accompanied by a risk to life or health.
Exchange transactions in the onion network may have no guarantees at all that the transaction will be successful. In deep web, everything works on credibility / reputation, and the higher the seller’s rating, the higher the likelihood of a successful outcome of the transaction. In the same place, you can sell tagged or stolen cryptocurrency assets. For this, there are special mixing sites to hide the criminal trail. These types of exchange operations are the most unreliable.
For this reason, one of the safest types of exchange operations is large centralized cryptocurrency exchanges. Such centralized services, sometimes using their position, impose their own rules, which leads to a loss of users’ material values.
PORTBITX is designed to empower cryptographic protection for maximum convenience and simplicity, as well as to protect the funds and personal data of users.
PORTBITX connects all cryptocurrency assets into one transport hub and creates highly efficient curvilinear isolation of the currency to make cryptocurrency as safe and close to people as possible.

6 Segment

A registered user of the PORTBITX portal can be any person supporting the general idea of ​​a free society. Our users are anonymous and financially independent, with the right to vote and the right to receive common incomes obtained by the operation of the portal and the activity of the crypto community PORTBITX.
For whom we create a service:
It can be ordinary housewives, entrepreneurs, unemployed, self-employed, freelancers, people who invest in the future, wealthy investors, etc.
One of the advantages of the service is anonymity, which gives anyone the right to save and earn around the world online, without fear that tomorrow they will be forced to pay some strange fees or licenses.
Service users are interested in the distribution and real use of cryptocurrency.
Self-regulating community PORTBITX, respecting the rights of all project participants.
Service users are:
For trust in the trade service there will be a seller rating for all types of goods and services presented. There will be a book of reviews about each seller, where each buyer has the right to leave a review about the product or service. This scheme is actively used in Darknet. The basic principle: the more positive reviews, the more trust. Each seller values ​​his authority and thus provides the best possible product or service. The expression “customer is always right,” works because no one wants to lose their customers.Currently, according to blockchain.com, there are used 34 million people who hold their funds in Bitcoin. The remaining number of users is difficult to calculate, but according to our modest calculations, there are at least 2 times more other users in any other currency.
This suggests that there is still a great demand on the market for services of safe storage and exchange of cryptocurrency assets.

7 Bounty

Bounty is a reward of users for PR-activity: subscriptions on forums, maintenance of topics in local language versions, translation of documents into a local language, publications in social networks, blogs and so on.
The terms of the bounty are published in the user profile of the section Terms and conditions of the bounty campaign.
To participate in the bounty campaign, bounty hunter, you need to register on the site PORTBITX.
You agree to the terms and conditions of the Bounty campaign if you register and do Bounty Hunt.
Tasks and their description are listed in the special section “Bounty Hunt”.
Each task is individual and has its own characteristics, so bounty hunters are invited to carefully study the conditions of each task.
Rewards are described in each task separately. The results of remuneration depend on the correct execution of the task.The remuneration is charged to the user’s personal account in the personal account.
There is also a payment history for completed tasks.
After the last fundraising stage, all information will be deleted in favor of the anonymity of users. We will also delete information about site visits and personal information that was required to specify to receive a reward. In the case of a request by third parties for data, we did not have information that could harm bounty hunters.
The bounty budget is 14,325,893 PORTBITX.
The distribution of tokens in stages is as follows:
Stage 1 – 6,325,000 PORTBITX;
Stage 2 – 4 000 000 PORTBITX;
Stage 3 – 4 000 893 PORTBITX.
Distribution of PORTBITX tokens:
If the ICO is not successful, the invested funds will be returned to investors, and the reward for bounty hunters will be canceled.
For this reason, we regulate and monitor the social activity of the bounty hunters so that the conduct of all ICO stages is successful.
For bounty campaigns, an application to the technical department is provided in order to correct them immediately in case of errors, as well as to assist the bounty hunters in carrying out their tasks.
We are building a healthy community, so we ask that the personal opinion and evaluation of the project PORTBITX of each participant be objective and adequate.
Each participant in the campaign bounty is our representative, and for us it is important to have a clear understanding of the face of responsibility and benefit that the community carries out.

8 Market

On the market there are many companies involved in the exchange and storage of cryptocurrency assets.
The number of such services is more than 16,000 and this is not the limit, but it is precisely in the face of fierce competition that truly unique and competitive projects are born.
This market situation motivates us to create a truly useful and necessary service in order to make the range of our service available to a wide range of people.
Recently, according to Google Trends, interest in cryptocurrency has fallen significantly. Now interest has rolled back to the area of ​​2016-17.
Cryptocurrency industry continues to function and develop. Now on the blockchain, you can create your own e-government, your own elections and currency, everything is limited only by the imagination of all industry participants.
The ecosystem is actively developing for the use of cryptocurrency in trading operations. Governments and regulators in different countries are seeking greater transparency in the cryptocurrency industry.
Some, such as the Japanese government, license and regulate crypto exchange and services. In Japan, cryptocurrency has long been accepted as a means of payment in many outlets. In states with despotic regimes and an unstable economy, one of the few tools for the preservation and enhancement of assets is Bitcoin, for this reason in these countries the rate can differ greatly from the average market rate.
The financial crisis and the instability of markets around the world continues to cause fear among people. In some countries want to ban circulation of dollars. Gold cannot be bought in the usual way and owners may experience some difficulties in working with it. Gold has long ceased to be a means of payment.
The priority for us is the safe storage of cryptocurrency assets, maximum user convenience and integration, the popularization of the cryptoindustry in everyday life.
In order for cryptocurrency assets to be used and an integral part of human activity, we want to form a stable market. At the moment, the capitalization of the entire market for a number of years fluctuates in the range of $ 100– $ 300 billion. The range of exchange operations ranges from $ 13-16 billion per day. The number of cryptocurrency assets represented on the markets is more than 2000 types.
The dominance of the main cryptocurrency Bitcoin is in the range of 49-52% of the entire market.
The tendency to reduce the main quotes scares potential investors, but this is not a reason for surrendering positions to a multi-million dollar audience of crypto enthusiasts. The reason why people continue to create new projects and new systems for exchange and transactional systems is the benefits they bring to humanity. In the market, as well as around the world, there are many unscrupulous developers who need to fight.
We are engaged in creating and securing the credibility of the cryptoindustry so that the user can choose a reliable service or network, and not imposed by anyone. This is one of the fundamental aspects of a free community. The right of choice for the user, “the client is always right” is an integral part of the philosophy of the PORTBITX project. By the level of their responsibility, transparency, advanced thought, innovation, in the future, the work of PORTBITX will judge all cryptomir. The better we, PORTBITX work for the good of society, the more trust we have and the more users use the PORTBITX service.
PORTBITX is part of a new culture, part of an ecosystem where the core value is reputation based on trust. This is a project where reputation is more important than money, and utility and service to people is more important than ostentatious hospitality and external gloss, and the safety of the assets of our project participants is more important than our profit indicators.
Capitalization is growing steadily from year to year.
At the beginning of 2017, the capacity of the crypto market was around $ 19 billion. Now capitalization has grown to $ 200 billion. The growth is colossal, but the market is still young and there will be many more challenges on the way to which all market participants will have to respond. And our participants will be the most prepared.
The number of new blockchains and new projects is growing, and the number of participants in the crypto market is also growing. As a result, the attitude of people to the cryptoindustry is changing for the better, just like the cryptoindustry itself.
In 2017, the known cryptocurrency assets were less than 800 species, but now their number has grown. Now on the market represented more than 2,000 species.
Not all assets are honest, there are those whose purpose is to obtain short-term profits, which badly affects the reputation and trust in the cryptoindustry. But, if we recall the story of the beginning of our amazing world, then the price for one Bitcoin was $ 0.00000003. Since then, the situation in the cryptoindustry has changed dramatically.In the future, the cryptoindustry market is waiting for great popularity and that is why reliable and honest services for the storage and exchange of cryptocurrency assets like our project will be needed.
Sharp volatility is such because the market is relatively young and has not reached even a tenth of its potential and capitalization. Therefore, the time in which we live is just a starting point. The world has already passed the Rubicon and there is a long and interesting road ahead.
The potential market we can serve in the future is more than one billion users. Now this market is slightly less than 50 million users.
Experts expect that in the future cryptocurrencies will replace the official fiat money.

9 Product

PORTBITX is a digital portal for storing, exchanging and trading cryptocurrency assets, as well as a platform for selling goods and services for cryptocurrency.
The service is managed by the community by voting. Voting topics are offered through a special application in the voting section.
Service has three main areas.
Secure storage of cryptocurrency.
Secure storage of over 1500 different cryptoactive assets. Safety is ensured by safe cold the repository.
The service itself is not directly connected to the repository to prevent the penetration of potentially dangerous programs. The security of user data in the service itself is protected by a local block chain. The entire database and operations are recorded on the principle of a distributed registry. Hacking one server should do this with hundreds of others located in different places. Mining in this block chain is not performed because all the costs of maintaining such security are borne by the service itself.
The PORTBITX development team is fully responsible for the security of cryptocurrency assets and for the operation of the service. One of the most vulnerable links in the safety chain is the human factor (concerns not only users, but also developers). For this reason, it is necessary to double-check scenarios, conduct stress testing and carefully select personnel.
Exchange
This is a portal for exchanging all available cryptocurrency assets for any other. The number of assets available on the portal will be recorded in the blockchain for a reliable display of the volume, the number of wallets, users and information on all the operations performed since the launch of the main network will also be indicated in the blockchain.
Any cryptocurrency asset can be exchanged for any other if it is in demand. The market decides for itself how and in what to trade. All exchange orders will be visible in online charts. Potentially, we will add more than 2,500,000 pairs to the portal, but not immediately, but in parts and as each cryptocurrency asset is checked. Also the choice for coins or tokens will always be behind the PORTBITX community. After each vote, all results will be published in the section “Voting” and on the official website of the service.
The portal has a convenient interface and an open registry, i.e. users will be able to monitor and control the network with developers. Also, with certain voting results, there may be additions to the network.In the future, we want to release the service in free navigation and stop controlling the network. If we succeed, we will open source code and create jobs for miners.
Marketplace
Marketplace is valid for the sale of services and products for cryptocurrency. High-quality and convenient service. All transactions on the Marketplace are recorded in the main register of the local blockchain. A wide range of products available advertising products and services, two types of payment (with a guarantee and with a reputation) to choose from.
The following portal functionality:
Voting / referendum
An important component of the PORTBITX portal is voting / referendum.
A variety of topics and surveys can be submitted to a vote, directly related to the PORTBITX community and the portal itself. For example, changes in tariff rates, adding new tokens, adding new services and additions to the service.
The right to vote is the right to decide the fate of the community, the right to find the best solution to the problems, the right to be free, honest and fair.
One voice is 5000 PORTBITX. (this limit can be lowered if the community decides on a general vote).
Since tokens can be sold on third-party services, they cannot automatically take part in voting. Also, all available tokens on the portal should be frozen for a period of voting that lasts no more than 24 hours, starting at 00:00 Central European Time.
Tokens are frozen through the user’s personal account in the voting section.Persons who do not have enough tokens for voting, but having the right to profit PORTBITX have the opportunity to see the voting results, as well as to make their proposals for the next vote.
Persons who do not have enough tokens for the right to vote and the right to profit will have the opportunity to group together for collective voting.
Results and coverage of all voting results will be immediately published after the end on the portal’s main page.
A vote is considered legitimate if a quorum gains 65% of the total number of votes. The decision on the outcome of the vote can be made if the number of those who agreed to 100% of those who participated in the vote is 60%. Voting can be repeated if uncrowded by a majority. In this case, the proposal will be revised. The deadline for a deferred vote may pass unplanned within two weeks after the end of the first vote. If, in the second ballot, the majority of votes will also not reach the bulk of 60%, then this issue will be postponed or canceled and will not be considered within the next 6 months.
The right to vote is not just an opportunity to influence the portal, it is the will of the community that developers must obey.
The right to profit
The right to profit is obtained by freezing tokens through the user’s personal account for a period of at least one month. The number of tokens needed to make a profit of at least 1000 PORTBITX.
The calculation of the distribution of profits are as follows.
All profits from all services provided by the service for a certain period of time in the tokens in which the activity was performed are distributed in relation to all community members who have frozen the tokens directly on the service portal. The profit is distributed in the same currencies in which it was received on the service.
In the event that the frozen asset of the PORTBITX tokens is defrosted ahead of time, then the profit it receives during this period will be distributed among the other participants whose tokens remain frozen.
Participation in the project is proved by deed and rewarded, in all fairness.
All profits, namely the estimated profits of users during and at the end of the period can be tracked and seen in the registry on the main page accessible to all interested parties.
PORTBITX developers do not hide revenues and honestly share them with the community.
Each user has the opportunity to check the registry and find their own account.Maximum openness and transparency is the key to trust and success of the service.

10 Road Map

11 Economy and Demand

All information on the movement of funds and their spending will be published on the official website of the company in a special reporting form.
All actions performed by PORTBITX will be covered in the news section of the company’s website.The voting results and the timing of their holding, as well as the topics discussed for voting will be in the user’s personal account in the “voting” section.To date, only about 80 million people have a cryptocurrency, store it or use it in payments.
Now there’s practically no way to find a person who hasn’t heard about bitcoin or blockchain at least once. The cause of mistrust is people who undermine the true face and good intentions of the founding pioneers of the cryptoindustry.
The market is too small and hypervolatil, but this trend will continue only for some time, until the total market capitalization reaches 1 trillion. USD This milestone will further open the way to even more people who want to be part of the crypto world. A larger number of participants will make this market more stable and less prone to hypervolatility.Unfortunately, there are many scammers and individuals who undermine the basis of the industry, and its usefulness. Therefore, the PORTBITX development team creates a service safe for the safety of users’ funds.
According to statistics provided by Blockchain.com from March 2018 to February 2019, the number of new users who registered new cryptocurrency wallets increased from 23 million to 33 million. Based on the data obtained, it can be concluded that there is a need for reliable storage of their cryptocurrency assets.
The year 2019 is a preparatory platform for an even larger number of users, so we decided to create a portal for the ecosystem of the cryptocurrency industry.

12 Project Team

One of the important factors in the decision making for an investor is the transparency and fame of the team that works on the project. An investor can check team members, evaluate and decide on investments. The knowledge and experience of the team is a kind of guarantee that the project will be implemented, but as is often the case in real life, this may be far from reality.
In the cryptoindustry, nothing can be 100% sure. Any ICO defaults to scam.
If you have doubts about our decency, we suggest investing a small amount.
By collecting the minimum amount, we will demonstrate in practice that we are credible, because our goal is to benefit the community.

13 Investments

The minimum capitalization of the project at the first stage is 1,450 ETH.
The minimum total capitalization of the project will be 56,000 ETH.
The maximum capitalization of the project can reach more than 160,450 ETH.
Tokens will be issued in the amount of 143,258,928.57142.

The opportunity to receive a bonus will be among the participants of the Bounty campaign and among ICO investors, but by decision of the crypto community.

15 Legal aspects

Placement of the company – Blockchain. This is due to the fact that we approach the project with full responsibility and are aware of the consequences of our actions, as well as due to pressure from some states and their unfriendly policy to the cryptoindustry.
Also, the service will not be present fiatnye currency, as their existence is not combined with the philosophy of our company. We will temporarily not specify the location of the company, as well as disclose the names of developers for the safety of their rights to life, health and freedom.
Since we consider ourselves a free community, some data for the sake of security for the sake of this freedom will be hidden from outsiders.
We guarantee a refund in case of unsuccessful first stage at 100% minus the miners commission.
This is important because the tools incorporated in the first stage are necessary for creating the kernel and the subsequent imposition of software modules.
We considered options for direct investment in the project from private investors, but since these investors could influence our strategy and policies, and since they could take some of the functions from the community, we decided to invest in our project as a community by Ico.
The risk of investing in our project, of course, is great, but we want to build a really useful service for the industry as a whole and for each user of the service separately. Therefore, we enable the community to judge us by our work.
