In March 2013 the blockchain temporarily split into two independent chains with different rules due to a bug in version 0.8 of the bitcoin software. The two blockchains operated simultaneously for six hours, each with its own version of the transaction history from the moment of the split. Normal operation was restored when the majority of the network downgraded to version 0.7 of the bitcoin software, selecting the backward compatible version of the blockchain. As a result, this blockchain became the longest chain and could be accepted by all participants, regardless of their bitcoin software version.[42] During the split, the Mt. Gox exchange briefly halted bitcoin deposits and the price dropped by 23% to $37[42][43] before recovering to previous level of approximately $48 in the following hours.[44] The US Financial Crimes Enforcement Network (FinCEN) established regulatory guidelines for "decentralized virtual currencies" such as bitcoin, classifying American bitcoin miners who sell their generated bitcoins as Money Service Businesses (MSBs), that are subject to registration or other legal obligations.[45][46][47] In April, exchanges BitInstant and Mt. Gox experienced processing delays due to insufficient capacity[48] resulting in the bitcoin price dropping from $266 to $76 before returning to $160 within six hours.[49] The bitcoin price rose to $259 on 10 April, but then crashed by 83% to $45 over the next three days.[40] On 15 May 2013, US authorities seized accounts associated with Mt. Gox after discovering it had not registered as a money transmitter with FinCEN in the US.[50][51] On 23 June 2013, the US Drug Enforcement Administration listed ₿11.02 as a seized asset in a United States Department of Justice seizure notice pursuant to 21 U.S.C. § 881.[52][better source needed] This marked the first time a government agency had seized bitcoin.[53] The FBI seized about ₿30,000[54] in October 2013 from the dark web website Silk Road during the arrest of Ross William Ulbricht.[55][56][57] These bitcoins were sold at blind auction by the United States Marshals Service to venture capital investor Tim Draper.[54] Bitcoin's price rose to $755 on 19 November and crashed by 50% to $378 the same day. On 30 November 2013 the price reached $1,163 before starting a long-term crash, declining by 87% to $152 in January 2015.[40] On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.[58] After the announcement, the value of bitcoins dropped,[59] and Baidu no longer accepted bitcoins for certain services.[60] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[61]

Почему Bitcoin актив

В обеих сетях используется один и тот же протокол Proof-of-Work – «доказательство работы». Это означает, что для майнинга используются вычислительные мощности компьютеров, гарантирующие защиту от двойного расходования и хакерских атак. И если в Bitcoin есть установленный потолок эмиссии (21 000 000), то в Ethereum его нет. Именно по этой причине команда Эфириум рассматривает варианты с переходом на алгоритм Proof-of-Stake (доказательство доли) и возможным «сжиганием» части добытых монет. Подобные разговоры показывают еще одно отличие Ethereum от Bitcoin – гибкость. Платформу легче изменять, обновлять и модернизировать.

On 3 January 2009, the bitcoin network was created when Nakamoto mined the first block of the chain, known as the genesis block.[25][26] Embedded in the coinbase of this block was the text "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks".[16] This note references a headline published by The Times and has been interpreted as both a timestamp and a comment on the instability caused by fractional-reserve banking.[27]:18
Прошедшая неделя оказалась для криптовалютной индустрии одной из наиболее запоминающихся в 2019 году – долго ожидавшийся запуск платформы Bakkt, наконец, состоялся, однако роста рынка, как предполагали многие, не случилось.

On 29 Novemvber 2017, South Korean Prime Minister Lee Nak-yeon raised concerns that cryptocurrencies were corrupting the youth of South Korea, remarking “There are cases in which young Koreans including students are jumping in to make quick money and virtual currencies are used in illegal activities like drug dealing or multi-level marketing for frauds”.[237]

Если предельно всё упростить, то объяснить феномен биткоинов можно на примере крышечек от лимонада (да, привет фанатам Fallout). Допустим, подделать эти крышечки нельзя, пробежаться по магазинам и скупить весь лимонад тоже: он больше не производится. Количество крышек ограниченно и заранее известно, так что надо просто бродить и смотреть под ноги — вдруг наткнётесь на крышечку.
The overwhelming majority of bitcoin transactions take place on a cryptocurrency exchange, rather than being used in transactions with merchants.[147] Delays processing payments through the blockchain of about ten minutes make bitcoin use very difficult in a retail setting. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies.[36] Merchants that do accept bitcoin payments may use payment service providers to perform the conversions.[148]

^ The word bitcoin first occurred and was defined in the white paper[4] that was published on 31 October 2008.[10] It is a compound of the words bit and coin.[11] There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, to refer to the unit of account.[12] The Wall Street Journal,[13] The Chronicle of Higher Education,[14] and the Oxford English Dictionary[11] advocate use of lowercase bitcoin in all cases, a convention followed throughout this article.

Что такое Bitcoin в двух словах

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]
