The technology at the heart of bitcoin and other virtual currencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.

Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto[15] and started in 2009[16] when its source code was released as open-source software.[7]:ch. 1 Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.[17] Research produced by University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[18]

Another type of physical wallet called a hardware wallet keeps credentials offline while facilitating transactions.[112] The hardware wallet acts as a computer peripheral and signs transactions as requested by the user, who must press a button on the wallet to confirm that they intended to make the transaction. Hardware wallets never expose their private keys, keeping bitcoins in cold storage even when used with computers that may be compromised by malware.[105]:42–45
The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted.[93] As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations of the given block) increases.[80]

Вместо того чтобы создавать новый блокчейн каждый раз, когда кто-то хочет создать свой дапп, можно использовать существующую инфраструктуру эфириума. Сравните строительство дома своими силами в чистом поле с наймом команды профессионалов, которые всё продумали за вас. Эфириум позволил практически каждому создавать собственные криптовалюты и даппы без особых проблем.

Ethereum's blockchain uses Merkle trees, for security reasons, to improve scalability, and to optimize transaction hashing.[60] As with any Merkle tree implementation, it allows for storage savings, set membership proofs (called "Merkle proofs"), and light client synchronization. The Ethereum network has at times faced congestion problems, for example, congestion occurred during late 2017 in relation to Cryptokitties.[61]

Как удалось создать подобную среду? Благодаря виртуальной машине Эфириум (EVM). Она представляет собой машину Тьюринга и компилирует умные контракты в байт-код перед их дальнейшей отправкой в блокчейн. Здесь также используются циклы, что гарантирует выполнение практически любых операций по умным контрактам. Потенциально «бесконечные» циклы отсеиваются платформой через механизм, именуемый газом (gas). При этом вы не будете платить за использование этой мощной вычислительной машины. Все расходы берет на себя сеть.

The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.[228] In the United States, the FBI prepared an intelligence assessment,[229] the SEC issued a pointed warning about investment schemes using virtual currencies,[228] and the U.S. Senate held a hearing on virtual currencies in November 2013.[230] The U.S. government claimed that bitcoin was used to facilitate payments related to Russian interference in the 2016 United States elections.[231]

Как криптовалюта использует криптографию


In Ethereum all smart contracts are stored publicly on every node of the blockchain, which has costs.[56] Being a blockchain means it is secure by design and is an example of a distributed computing system with high Byzantine fault tolerance. The downside is that performance issues arise in that every node is calculating all the smart contracts in real time, resulting in lower speeds.[56] As of January 2016, the Ethereum protocol could process about 25 transactions per second.[56] In comparison, the Visa payment platform processes 45,000 payments per second leading some to question the scalability of Ethereum.[57] On 19 December 2016, Ethereum exceeded one million transactions in a single day for the first time.[58]
Конечная цель майнинга – подбор цифровой подписи, закрывающей блок. Как только это происходит, блок закрывается, майнер получает вознаграждение и начинает формироваться новый блок. Для добычи разных криптовалют задействуется мощности процессора (CPU), видеокарт (GPU) или специализированное оборудование (ASIC, FPGA). Майнинг – это один из способов заработка криптовалют.

According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[180]

Несмотря на весь этот быстрый прогресс, судьба криптовалют слишком сильно зависит от властей. К счастью, многим правительствам ясно, что криптовалюты имеют огромную ценность, которую пока сложно осознать до конца. По мере того в криптоэкономику будут поступать триллионы долларов, многие страны, скорее всего, попытаются выбиться в лидеры криптовалютного пространства.
The "Metropolis Part 1: Byzantium" soft[citation needed] fork took effect on 16 October 2017, and included changes to reduce the complexity of the EVM and provide more flexibility for smart contract developers. Byzantium also added supports for zk-SNARKs (from Zcash), with the first zk-SNARK transaction occurring on testnet on September 19, 2017.[citation needed]
On 1 August 2017, a hard fork of bitcoin was created, known as Bitcoin Cash.[117] Bitcoin Cash has a larger block size limit and had an identical blockchain at the time of fork. On 24 October 2017 another hard fork, Bitcoin Gold, was created. Bitcoin Gold changes the proof-of-work algorithm used in mining, as the developers felt that mining had become too specialized.[118]

The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.[169] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[170] In the latter half of 2012 and during the 2012–13 Cypriot financial crisis, the bitcoin price began to rise,[171] reaching a high of US$266 on 10 April 2013, before crashing to around US$50. On 29 November 2013, the cost of one bitcoin rose to a peak of US$1,242.[172] In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. As of August 2014 it was under US$600.[173] During their time as bitcoin developers, Gavin Andresen[174] and Mike Hearn[175] warned that bubbles may occur.

Ethereum is an open source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. It supports a modified version of Nakamoto consensus via transaction-based state transitions. Ether is a cryptocurrency generated by the Ethereum platform and used to compensate mining nodes for computations performed.[3] Each Ethereum account has an ether balance and ether may be transferred from one account to another.
Ethereum was initially described in a white paper by Vitalik Buterin,[10] a programmer involved with Bitcoin Magazine, in late 2013 with a goal of building decentralized applications.[11][12] Buterin had argued that Bitcoin needed a scripting language for application development. Failing to gain agreement, he proposed development of a new platform with a more general scripting language.[4]:88
