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]

Litecoin broke below the critical support of $61.75 on September 24. That was followed by further selling that dragged prices to $50.25 on September 26. Currently, the bulls are attempting a pullback that is likely to face resistance at $61.75. Both moving averages are sloping down and the RSI is close to the oversold zone, which suggests that bears are in the...

Сообщество Ethereum обсуждало, следует ли вернуть эфир инвесторам и каким именно способом осуществить возврат, а разработчики The DAO из Германии пытались ответно атаковать хакера[33], поскольку децентрализованный характер The DAO и Ethereum означают отсутствие центрального органа, который мог бы предпринять быстрое действие, и требуют согласия пользователей[31]. После обсуждения в течение нескольких недель 20 июля 2016 года над проектом Ethereum был произведён хардфорк[34] (развилка цепочки блоков, а не программного кода), чтобы отменить взлом и вернуть инвесторам средства, похищенные у The DAO[35]. Это было первое ответвление цепочки блоков с целью возвращения похищенных средств инвесторам[36].

Что такое Binance криптовалюта

The first wallet program, simply named Bitcoin, and sometimes referred to as the Satoshi client, was released in 2009 by Satoshi Nakamoto as open-source software.[16] In version 0.5 the client moved from the wxWidgets user interface toolkit to Qt, and the whole bundle was referred to as Bitcoin-Qt.[113] After the release of version 0.9, the software bundle was renamed Bitcoin Core to distinguish itself from the underlying network.[114][115]
Vitalik Buterin picked the name Ethereum after browsing Wikipedia articles about elements and science fiction, when he found the name, noting, "I immediately realized that I liked it better than all of the other alternatives that I had seen; I suppose it was the fact that sounded nice and it had the word 'ether', referring to the hypothetical invisible medium that permeates the universe and allows light to travel."[9]
Transactions are defined using a Forth-like scripting language.[7]:ch. 5 Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain.[82] The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction. As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer.[82] Any input satoshis not accounted for in the transaction outputs become the transaction fee.[82]

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
