Weekly Dev Update #19

THORChain Weekly Dev Update for Week 19–02 Nov 2019


1 Rune Fee

Reasoning about gas costs on networks with non-deterministic fee schedules (such as Bitcoin) becomes unnecessarily complex. The issue is that the final gas cost cannot be known ahead of time so the system must cover any variability in the gas cost so that the user can be charged a flat rate. If the user is not charged anything, then the system can be depleted of funds, passing the cost back to stakers. Additionally, swaps below 1 Rune bring negligible economic value to the network and saturate the mempool with low value transactions. As such the solution is to charge a flat 1 Rune fee (or 1 Rune equivalent) on all outgoing transactions (swap and withdrawals). This 1 Rune fee is moved into the Protocol Reserve and increases the network’s future income. When the nodes report on the final transaction, they include the observed transaction fee. This transaction fee is then reimbursed back to the pool that paid for it ( BNB.BNB, BTC.BTC, ETH.ETH etc). There are cases that the outgoing transaction fee may exceed 1 Rune (Bitcoin in high use), but more than likely 1 Rune will be more than sufficient to cover the costs and ensure the network grows its reserves. Additionally, it sets a floor on the minimum transaction that the network will process. A swap of less than 1 Rune will end up becoming a donation to the network.

THORChain Development

The team are working on 4 parallel streams of effort. Cross-chain infrastructure has now been merged into a single repo called “THORNode”. * THORChain * Midgard Public API * Threshold Signature Scheme implementation * Front-end Integration for BEPSwap


Much work has been done to refactor and clean up the codebase which will make public audits easier. This includes splitting up the keeper, separating out the events module and more. Smoke tests have been fully-integrated into the test schedule. Safer subtraction and division methods were added to prevent the likelihood of panic events. * [refactor] split keeper funcs/interface into separate files * [tests] use gow * [refactor] Redo how get key works in keeper * [security] require no signers on tx ins * Resolve “ADD: 1 Rune Fee on all Swaps” * [bug] fix smoke tests * [ADD] semantic versioning * [Refactor] Keeper chains * [Refactor] Events Keeper * Resolve “Adds a SafeSub method” * [Refactor] Last Height Keeper * [Refactor] keeper liquidity fees * FIX: Issue 208 * [ISSUE] Get smoke tests to 100%

Midgard Public API

Midgard is now ready for integration into the FrontEnd. The manner in which USD price of assets in now updated to source only from internal pool pricing. This includes BNB.BUSD, BNB.TUSD, BNB.USDS. ROI endpoints are now added. * Fix : Updated our mock data to include a correct BNB address. * Add: Return the date a staker first staked. * Add: Previously missing implementations for pool data (24hr and 12m). * Fix: Several potential query issues. Updates to return the TX date as a UNIX timestamp. * Fix: Additional query updates/fixes. * Fix: Build system * Add: Filtering implementation for TxID and Asset. * Added missing import. * Fix/build issues * Fixed issue with my auto refactor * Add: Filtering updates. DB Config fix. * Add: Missing Staker methods for ROI and earnings. * Added fix to enabled timescale extension * Fix: Added build config for rpc_host * Add: Support to Calculate USD price of an asset. * Added: Health check for mainnet to test that we still have a db connection… * Add: Tests for the recent endpoints work. * jq syntax fix. * Additional jq fixes. * [ADD] Manage docker image on gitlab

Threshold Signature Scheme

The Binance Go TSS library is now fully implemented and deploys in a four-node chain. integrate with new go-tss * 212-issue export private key thus we can use it to start tss * 214-issue consolidate tss keygen and tss keysign config, with our new go-tss… * [ADD] Setup go-tss in genesis docker * [ADD] Have CI run smoke tests on a four node chain with TSS

Frontend Implementation

The frontend makes some final tweaks on the interface, before integrating the Midgard APIs. * Resolve “Update stake page share panel” * Resolve “UPDATE: Network Dropdown Titles” * Resolve “ADD: Sorting of columns in pool list” * Resolve “ADD: Sorting of columns in pool list” * Resolve “FIX: Close token selection drop down when clicking outside” * Resolve “Add redux saga for midgard apis” * Resolve “Update protect price UI” * Resolve “Update wallet drawer”


The next milestone is: ChaosNet: 03 January 2020 on-time

Daily analysis of cryptocurrencies 20191126(Market index 21— Extreme Fear state)

Daily analysis of cryptocurrencies 20191126(Market index 21— Extreme Fear state)

The ECB Is Now Studying The Option Of Introducing A Digital Currency Benoit Coeure, member of the Executive Board of the European Central Bank (ECB), has said Europe must overcome its reliance on international payment providers. However, it is not the central bank’s job to come to the rescue and crowd out private sector initiatives. The ECB is now studying the option of introducing a digital currency, and this would have broader consequences for the banks. Coeure warned against the central bank crowding out private-sector players. The ECB recently introduced an instant payment system called TIPS for transactions between banks, but lenders have been slow to join and the scheme has not had a significant impact so far.
Former PBoC Head: China’s Digital Currency To Emphasize On Payment And Retail Usage According to a report, when it comes to whether global central banks will issue digital currency, ZHOU Xiaochuan, president of China Society for Finance and Banking and former head of the People’s Bank of China, believes that China will continue to adhere to the past path, emphasizing digital currency’s usage in the payment and retail. Big countries are very cautious when choosing technical directions at the currency level. If they go in the wrong direction, a crisis of trust may arise. China will emphasize digital currency’s payment function and maintain favorable technical support for the retail system. Based on this, it will gradually consider expanding the use of digital currency.
Thai Excise Department Will Devise A Blockchain Tax Refund System According to Bangkok Post, the Thailand Excise Department will devise a method to refund overpaid taxes to oil exporters in a manner that stems leakages, its chief says. The change in the tax refund practice will use blockchain, which the department plans to adopt by the middle of next year, said director-general Patchara Anuntasilpa. The blockchain-based tax payback system requires oil exporters to pay excise tax to the department and claim overpaid taxes after they ship the fuel, he said. The new technology will let the department inspect the tax payments thoroughly.

Earlier this month, we discussed the chances of bitcoin hitting $7,400 and $6,500 against the US Dollar. BTC did decline heavily and recently tested the main $6,500 support area.
A new multi-month low was formed near $6,535 before the price started an upside correction. There was a strong recovery after the price surpassed the $6,750 resistance area. Besides, the price rallied more than 10% to climb above the $7,000 resistance.
More importantly, yesterday’s key bearish trend line was breached with resistance near $7,060 on the hourly chart of the BTC/USD pair. The pair even spiked above the 100 hourly simple moving average and tested the $7,350 resistance area.
A high was formed near $7,372 and bitcoin price is currently trimming gains. It traded below the $7,200 level. Additionally, there was a break below the 23.6% Fib retracement level of the recent wave from the $6,535 low to $7,372 high.

Wolfpack bot.......

About some years ago, one of my friends hailed his belief in Bitcoin and explained how he moved his whole life savings onto a hardware wallet and erudite his private alphanumeric key. He sounded like a character from a Neal Stephenson novel-gritty, daring and irreverent of the world’s established banking systems. While Bitcoin has soared since then and made him a millionaire many times over, the question now is if it will continue to rise in value or if it’s already reached its height.
A digital currency “crypto currency” that has no tangible paper or physical coin representation. Instead, encryption techniques using computers and open source software generate the currency based on mathematical proof, or blockchains. Cryptocurrencies such as Bitcoin are decentralized: There’s no place like a bank where the currency is held, and a private security key tied to an open source ledger proves who holds the value. As an electronic payment system, cryptocurrencies are instantaneous and have low transaction fees compared to traditional banking systems, which are comparatively slow and have high fees associated.

Blockchain Wallets

Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services.
By the way, we developed the best blockchain platform:
[] (
We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms.
What a Blockchain Wallet is? What is its purpose?
Find the answer after reading this article.
Public/Private Key
The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver.
Accessing wallets
Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals.
Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets.
Types of Wallets & Storage Methods
The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners.
Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens.
Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples.
Hardware wallets — LedgeTrezoAlternatives
Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers.
Paper Wallets
Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper!
Real World Historical Examples of Different Wallet Types
Web Wallet: Brief mechanism & Security is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops.
Neon Wallet
The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as and They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible.
Real World Example — Poor Practices
MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets.
In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes.
Case Study: Good Practice Binance, the Attempted Hack
During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt.
Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations
As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange.
Hardware Wallets Advantages and Limitations
We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations.
Paper Wallets Advantages and Limitations
Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever.
Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security
Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose.
You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait.
How to Monitor Funds
There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor.

Here on Cryptoindex blog, we would like to tell you more about each coin selected by our powerful Cryptoindex AI-based algorithm. We’ll be posting one article about one coin from the portfolio with #cix100coinreviewhashtag.
Today we would like to review Cardano and their further plans.
So what is Cardano? And why does this coin take the TOP-10? Let's look at this project.
Cardano was released on September 29, 2017, under the 'Byron' bootstrap phase with the official launch in Japan. Cardano has been developed by the company for the development of the input-output module Hong Kong (IOHK). Charles Hoskinson, former co-founder of BitShares, Ethereum, and Ethereum Classic, is currently focused on aiming all of the company’s resources at launching smart contracts, decentralized applications, sidechains and multi-party computing.
The platform is setting a course towards creating a new decentralized economy and democratization of finance in emerging markets. The technology will allow the creation of decentralized applications and make smart contracts that are simultaneously inexpensive, safe and scalable.
How does this technology differ from others?
Blockchain technology will soon be used globally. Prior to its sucсess, it had several critical issues, such as the absence of regulatory oversight, the experimental development of software with unproven security, poor management reducing the ability to plan long term. But the Cardano project is very different: Like a Ripple it considers the need for regulatory oversight, preserving the privacy and protection of consumers through an innovative software architecture. The protocol itself contains a multilevel, block-based block-block that is flexible, scalable and developed using the most rigorous academic and commercial software standards in the industry. Cardano will use a system of democratic governance that will allow the project to evolve over time and to sustainably fund itself through a system of vision of applicants.
Unique technology
Transactions involving ADA are publicly registered through the blockchain, allowing you to see the date and time of the transaction, the amount sent and the sender's common address. The real version according to the developers will be launched very soon one version of Cardano ‘Testnet’ is already active.
Cryptocurrency ADA works on its own level, called Cardano Settlement Layer (CSL). CSL is the level of accounting and support for operations with cryptocurrency wallets. The second layer, called the Cardano Computation Layer (CCL), will support smart contracts and decentralized applications. This multi-level architecture allows you to simplify updates.
How is Cardano's control organized?
Cardano is a project consists of three institutions that have separate roles, all of which contribute to the development of the project:
  1. The Cardano Foundation is responsible for the "standardization, protection and promotion" of Cardano technology. 2.IOHK is a world-class blockchain engineering company responsible for the Cardano blockchain construction. 3.Emurgo is responsible for the development of commercial applications created on the Cardano ecosystem. The original ideas about Cardano were initiated by a group of cryptocurrency enthusiasts, investors, and entrepreneurs from Asia at the end of 2014. The HK input project (IOHK) was involved in the development and implementation of Cardano. In addition, the Cardano Foundation, which is based in Switzerland and, was established to assist in supervising the development of Cardano, its ecosystem, activities, and protection on behalf of the users of the protocol. Another organization, Emurgo, based on the Isle of Man, was established to provide commercial activities on behalf of the ecosystem and the community. These three organizations are completely separated in ownership and leadership.
What is ADA? And what is its peculiarity?
ADA is a cryptocurrency in the Cardano system itself and it is used to receive and send money. The developers believe that digital money, such as ADA, shows how future money will be. This allows you to quickly transmit quickly value with guaranteed security through cryptography. To use ADA users should use the Daedalus wallet, which is a hierarchical deterministic, multi-platform, secure wallet designed specifically for this cryptocurrency. The wallet is easy to install and it allows you to view everything and perform a transaction search on demand. You use it to view specific information about the status of the blockchain. It also contains encrypted cost passwords and private keys for added security and the ability to export to a paper certificate for cold storage. The purchase of ADA can be done through unencrypted or encrypted redemption certificates, and users can set the level of the guarantee of the transaction. The Cardano team is also working on adding support for Ethereum Classic, Bitcoin and creating a mobile wallet for iOS and Android. They are also working on an application repository that includes support for almost all crypto and community-based applications, as well as creating bids that will allow ADA owners to generate blocks and thereby earn more than before.
How to buy ADA?
Currently, you can buy or sell ADA cryptocurrencies through several exchanges, the number of which is constantly growing. Cryptocurrency will also be available at some ATMs in Japan. Those who have an ADA will also be able to choose a Cardano debit card that allows you to use it like any other currency. The funds are automatically converted into your local currency for unimpeded use. The debit card will be connected to the application so you can track transactions and ADA balance. Currently, ADA can be purchased from Binance or Bittrex.
The project Cardano has all the prospects to become one of the most reliable blockchain platforms. The solutions that the company offers are far superior to its competitors, such as Ripple and Stellar. The company has a good team, competent management, and excellent technological solutions. All these qualities can help to achieve the company worldwide recognition, even despite such a high competition in the crypto world.
At the time of writing, Cardano is 1.63% of the total of CryptoIndex portfolio.

Backup Wallet.dat

"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal
1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need.
2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new".
3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it.
To put a real world example or two.
Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase).
Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost.
Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet.
Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe.
In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth
"Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!"
"Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth
"In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat.
Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob
"wallet is a collection of private keys"
"there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob
How to safely back up your wallet
Keep Your Crypto #SAFU (CZ's Tips)
To Read:
NOTE: As of version we have updated to HD wallets, so you should not need to worry about keypools anymore if you have upgraded
"Regarding the Sanctuary, you receive payments always to the same address (key), so the keypool is not consumed for those payments. But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward.
You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000.
The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them.
If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue
