In May of 2017, the world’s first ‘Lightning Network’ transaction took place using Litecoin, where 0.00000001 LTC was transferred from Zurich to San Francisco in less than one second. The open-source Litecoin software can be downloaded, used, modified and distributed by individuals without fear of corruption, as the independent verification of source code and binaries makes for a completely transparent process.


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]

Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.

Physical wallets store the credentials necessary to spend bitcoins offline and can be as simple as a paper printout of the private key:[7]:ch. 10 a paper wallet. A paper wallet is created with a keypair generated on a computer with no internet connection; the private key is written or printed onto the paper[h] and then erased from the computer. The paper wallet can then be stored in a safe physical location for later retrieval. Bitcoins stored using a paper wallet are said to be in cold storage.[105]:39 In a 2014 interview, QuadrigaCX founder Gerald Cotten explained that the company stored customer funds on paper wallets in safe deposit boxes: "So we just send money to them, we don’t need to go back to the bank every time we want to put money into it. We just send money from our Bitcoin app directly to those paper wallets, and keep it safe that way."[106]
Litecoin is an open source software project released under the MIT/X11 license which gives you the power to run, modify, and copy the software and to distribute, at your option, modified copies of the software.

On May 7, 2019, Binance revealed that it had been the victim of a “large scale security breach” in which hackers had stolen 7,000 Bitcoin worth around U.S.$40 million at the time.[11] Binance CEO Changpeng Zhao said the hackers “used a variety of techniques, including phishing, viruses and other attacks” and structured their transaction “in a way that passed our existing security checks.”[12] Binance halted further withdrawals and deposits but allowed trading to continue. The site pledged to reimburse customers through its secure asset fund.

A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold[99] or store bitcoins, due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A wallet is more correctly defined as something that "stores the digital credentials for your bitcoin holdings" and allows one to access (and spend) them.[7]:ch. 1, glossary Bitcoin uses public-key cryptography, in which two cryptographic keys, one public and one private, are generated.[100] At its most basic, a wallet is a collection of these keys.
Созданная и заложенная в Ethereum технология умных контрактов позволяет реализовать механизм автоматизации при осуществлении транзакций, предварительно просчитав все сопутствующие условия, а также непосредственно результат каждой отдельной взятой сделки. Такой подход должен гарантировать более высокие показатели стабильности в сравнении с биткоином, поскольку здесь никак нельзя влиять на условия, однако есть сложности с блокчейном Ethereum, о которых будет рассказано ниже.

Researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used.[36]:220–222 Bitcoin miners join large mining pools to minimize the variance of their income.[36]:215, 219–222[121]:3[122] Because transactions on the network are confirmed by miners, decentralization of the network requires that no single miner or mining pool obtains 51% of the hashing power, which would allow them to double-spend coins, prevent certain transactions from being verified and prevent other miners from earning income.[123] As of 2013 just six mining pools controlled 75% of overall bitcoin hashing power.[123] In 2014 mining pool Ghash.io obtained 51% hashing power which raised significant controversies about the safety of the network. The pool has voluntarily capped their hashing power at 39.99% and requested other pools to act responsibly for the benefit of the whole network.[124] c. 2017 over 70% of the hashing power and 90% of transactions were operating from China.[125]


Every 2,016 blocks (approximately 14 days at roughly 10 min per block), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.[7]:ch. 8 Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.[92]

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]

According to the European Central Bank, the decentralization of money offered by bitcoin has its theoretical roots in the Austrian school of economics, especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined,[133] in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.[134]:22

Технологические проблемы кажутся самыми лёгкими для преодоления. Недавние дополнения, такие как IOTA, могут предоставить неограниченную масштабируемость и почти мгновенные транзакции без каких-либо затрат. Так называемые стабильные монеты решают проблему волатильности, используя различные изобретательные методы, чтобы стоимость криптовалюты не колебалась. Меры безопасности усиливаются, а биржи, такие как NEX, становятся настоящими форт-ноксами криптосферы.
Full clients verify transactions directly by downloading a full copy of the blockchain (over 150 GB As of January 2018).[101] They are the most secure and reliable way of using the network, as trust in external parties is not required. Full clients check the validity of mined blocks, preventing them from transacting on a chain that breaks or alters network rules.[7]:ch. 1 Because of its size and complexity, downloading and verifying the entire blockchain is not suitable for all computing devices.
Как же много людей, которые относятся к криптовалюте с точки зрения «что такое не знаю, но осуждаю». И у всех этих юзверей крипта — МММ, и они точно знают, что «криптопузырь» лопнет… вот-вот, буквально чутка подождать. Когда начинается очередной восходящий виток, как-то затыкаются и лишь подквакивают «вот увидите, скоро всех обуют». Но стоит крипте просесть — всё, на улице этих личностей праздник: «видите, я говорил что это фантики, поделом вас наказали». И хоть бы один для разнообразия назвал точную дату, когда всё. А то врубают принцип ОБС, а потом пытаются сохранить лицо. Выходит, прямо скажем, отвратительно.

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.

Computing power is often bundled together or "pooled" to reduce variance in miner income. Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment. In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block.[98]

Вариант с майнингом требует начальных инвестиций, будь это самостоятельная добыча ETH, или использование облачных сервисов. Эфир – одна из основных опций «шахтеров», которые работают с пулами. Добыча происходит на фермах, составленных с мощных видеокарт от Radeon и GeForce. Но уже осенью 2017 появился первый ASIC для майнинга Ethereum. После чего и начались активные разговоры о переходе на протокол PoS. Как только сеть сделает этот переход, майнинг эфира станет экономически невыгодным. Поэтому ETH сложно рассматривать в качестве долгосрочной майнинговой опции.

Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control.[138] Dodd quotes a YouTube video, with Roger Ver, Jeff Berwick, Charlie Shrem, Andreas Antonopoulos, Gavin Wood, Trace Meyer and other proponents of bitcoin reading The Declaration of Bitcoin's Independence. The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian."[138][137]

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]

Передача криптовалют необратима — никто не может отменить, заблокировать, оспорить или принудительно (без приватного ключа) совершить транзакцию. Однако участники сделки могут добровольно временно взаимно блокировать свои криптовалюты в качестве залога или установить, что для завершения/отмены сделки требуется согласие всех (или произвольных дополнительных) сторон. Такие возможности имеются в смарт-контрактах и зависят от конкретного блокчейна.
An official investigation into bitcoin traders was reported in May 2018.[188] The U.S. Justice Department launched an investigation into possible price manipulation, including the techniques of spoofing and wash trades.[189][190][191] Traders in the U.S., the U.K, South Korea, and possibly other countries are being investigated.[188] Brett Redfearn, head of the U.S. Securities and Exchange Commission's Division of Trading and Markets, had identified several manipulation techniques of concern in March 2018.

LTC/USD Technical analysis. First day of Q4. Price seems to have finally slowed down near the $55 range after a harsh move down in the last week of September. Looking for more confirmation before entering any more positions. Very neutral for the time being. However, I think if price breaks $60, we could test the $66-$72 range rather quickly, but if price breaks...

In Charles Stross' 2013 science fiction novel, Neptune's Brood, the universal interstellar payment system is known as "bitcoin" and operates using cryptography.[238] Stross later blogged that the reference was intentional, saying "I wrote Neptune's Brood in 2011. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency."[239]

In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is mathematically unfeasible. Users can tell others or make public a bitcoin address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction. The network verifies the signature using the public key; the private key is never revealed.[7]:ch. 5

Новая эра Ethereum наступит вместе с переходом к версии Serenity. До этого также запланирован релиз Metropolis. Однако именно в Serenity реализуется переход с PoW на PoS, что должно сократить затраты на поддержку сети и обезопасить ее от пресловутой «Атаки 51% (когда 51% всей криптовалюты принадлежит одному владельцу). В дополнение к этому, рассматривается вариант с масштабированием сети путем шардинга, то есть, разделением на меньшие части.
