Bitcoin (BTC) is known as the first open-source, peer-to-peer, digital cryptocurrency that was developed and released by a group of unknown independent programmers named Satoshi Nakamoto in 2008. Cryptocoin doesn’t have any centralized server used for its issuing, transactions and storing, as it uses a distributed network public database technology named blockchain, which requires an electronic signature and is supported by a proof-of-work protocol to provide the security and legitimacy of money transactions. The issuing of Bitcoin is done by users with mining capabilities and is limited to 21 million coins. Currently, Bitcoin’s market cap surpasses $138 billion and this is the most popular kind of digital currency. Buying and selling cryptocurrency is available through special Bitcoin exchange platforms or ATMs.

Bloomberg reported that the largest 17 crypto merchant-processing services handled $69 million in June 2018, down from $411 million in September 2017. Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks, according to Nicholas Weaver, a researcher quoted by Bloomberg. High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer. However, bitcoin continues to be used for large-item purchases on sites such as Overstock.com, and for cross-border payments to freelancers and other vendors.[150]

Здравствуйте! Криптовалюты очень популярны в СМИ. Кто-то зарабатывает миллионы на росте курса, кто-то называет их очередным «пузырем». Политики обвиняют владельцев криптовалют в отмывании денег, а крупные магазины начинают принимать оплату в криптовалюте. Я сам несколько раз упоминал о криптовалютах, а сейчас решил объяснить, что такое криптовалюта и зачем она нужна — простым и понятным языком.

Является ли Bitcoin полезным в качестве валюты


Криптовалюты децентрализованны. У криптовалют новые монеты систематически и прозрачно создаются системой. Возьмите биткоин: его инфраструктура гарантирует, что только 21 млн. единиц будут когда-либо существовать. Теперь сравните это со случайным расширением и сокращением поставок фиатных валют, таких как евро, с лёгкой руки правительств и центральных банков.
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]
Уже несколько лет криптосообщество пугают тем, что однажды появятся квантовые компьютеры, которые взломают блокчейн за несколько минут, и крипторынку придет конец. Google считается лидером в гонке за создание квантовых компьютеров. 24 сентября 2019 года американское издание Financial Times заявило, что компания совершила прорыв в квантовых вычислениях, добившись «квантового превосходства» — эксперимента, продемонстрировавшего превосходство квантового компьютера […]

Майнинг — процесс поиска и подписи новых блоков. Для этого майнеры запускают на компьютере программу, которая занимается перебором и хешированием случайных чисел, пока кто-то из майнеров не найдет подходящие под условие число. Условия подбираются автоматически, чтобы обеспечить определенную скорость добычи блоков в зависимости от мощности компьютеров, занятых в майнинге. За найденное число майнер получает награду в крипте.

Welcome to the 34th Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of Constellation. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. Constellation launched in 2017 with a private sale that raised $35.2mn in exchange for 756mn DAG – the utility token for the Constellation Network. This amounted to 18.9% of the original 4,000,000,000 DAG maximum supply; however, as a gesture of good will, the founders burned the 288mn tokens originally allocated to them, leaving the maximum supply at 3.71bn DAG. The team raised no further funds following this. DAG was created as an ERC-20 token for accessibility purposes, but, upon the launch of the Mainnet in October, these tokens will be swapped for the native Directed Acyclic Graph tokens; hence the ticker, DAG.

На предпоследней неделе сентября мировое инвестиционное сообщество с удивлением наблюдало за тем, что происходит в финансовой системе США: неожиданно банки ощутили нехватку долларов, а 18 сентября Федеральная резервная система (ФРС) США во второй раз за последние два месяца понизила базовую процентную ставку на этот раз до интервала в 1.75–2%. Что же происходит с политикой ФРС […]

Холодный кошелек. Данные для доступа (адрес, пароли) хранятся в специальном файле wallet.dat. Почему бы не хранить этот файл там, где его никто не сможет украсть или подсмотреть, например, на отдельной флешке? Холодный кошелек — хранение данных на устройстве, которое вообще не подключено к интернету и защищено от посторонних. Не слишком удобно, зато очень безопасно, если хотите сделать большое вложение. Примеры: флешка, пароль на бумаге, хард-кошельки типа Trezor.
To be accepted by the rest of the network, a new block must contain a proof-of-work (PoW).[80] The system used is based on Adam Back's 1997 anti-spam scheme, Hashcash.[91][failed verification][4] The PoW requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.[7]:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...[7]:ch. 8) before meeting the difficulty target.

In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[242] The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers.[243][244]

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]
Many uses have been proposed for Ethereum platform, including ones that are impossible or unfeasible.[46][33] Use case proposals have included finance, the internet-of-things, farm-to-table produce, electricity sourcing and pricing, and sports betting. Ethereum is (as of 2017) the leading blockchain platform for initial coin offering projects, with over 50% market share.

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]
