Проблем с тем, чтобы купить эту криптовалюту или обменять на другие coins нет. Однако с экономической точки зрения у эфира есть несколько недостатков. Во-первых, это курс и механизмы, которые на него влияют. Если в случае с Bitcoin можно говорить о рыночном формировании цены, то в случае с Ethereum наблюдается прямая зависимость с успехами самой платформы. Стоит кому-то выпустить улучшенный вариант или найти недочет в Ethereum, как это обрушит стоимость токенов.
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]
Welcome to the 32nd Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of ExchangeCoin. 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. ExchangeCoin was launched in November 2017 with an ICO that raised 650 BTC, equating to over $5,000,000 at the time. The token issued, EXCC, has a maximum supply of 32,003,133, with 4mn EXCC sold during the ICO. Further, the project also has a premine of 12.1mn EXCC, equating to 37.95% of the maximum supply (from which the 4mn was sold to the public in the token sale). The token itself operates on the Equihash algorithm, and underwent a hard fork in July 2018, after which the network migrated to a dual Proof-of-Work/Proof-of-Stake consensus mechanism, with 30% of block rewards rewarded to stakers and 70% to miners. The block reward is progressively diminishing, with the current reward at 24.5 EXCC per block, with 2.5-minute block times.
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.
Криптографія з метою конфіденційних платежів почала використовуватися з 1990 року в системі DigiCash Девіда Чома, компанія якого збанкрутувала в 1998 році[14]. Однак, його платіжна система була централізованою, а вперше термін «криптовалюта» почав використовуватися після появи пірингової платіжної системи Bitcoin, яка була розроблена в 2009 році людиною або групою осіб під псевдонімом Сатосі Накамото[15] і використовує хешування SHA-256 і систему proof-of-work[16].

According to The New York Times, libertarians and anarchists were attracted to the idea. Early bitcoin supporter Roger Ver said: "At first, almost everyone who got involved did so for philosophical reasons. We saw bitcoin as a great idea, as a way to separate money from the state."[132] The Economist describes bitcoin as "a techno-anarchist project to create an online version of cash, a way for people to transact without the possibility of interference from malicious governments or banks".[135] Economist Paul Krugman argues that cryptocurrencies like bitcoin are "something of a cult" based in "paranoid fantasies" of government power.[136]


В феврале 2014 года криптовалюта оказалась в заголовках прессы из-за крупнейшего в мире обмена биткойнов: Mt. Gox объявила о банкротстве. Компания заявила, что она потеряла почти 473 миллиона долларов от биткойнов своих клиентов, вероятно, из-за кражи. Это эквивалентно примерно 750 000 биткойнов, или около 7 % всех существующих биткойнов. Из-за этого кризиса, среди прочих новостей, цена на биткойн упала с максимума примерно в 1,160 долларов в декабре до менее 400 долларов в феврале.[60]
В эфире телеканала CNBC партнер фонда Crypto Oracle и бывший аналитик банка Goldman Sachs Лу Кернер заявил, что биткоин (BTC) сможет взлететь до нового максимума и без поддержки институциональных инвесторов. По мнению финансиста, предыдущие фазы агрессивного роста первой криптовалюты наступали благодаря активизации розничных торговцев. Институционалы присоединяются к биткоину, но они на этом рынке далеко не первые и […]
The novel hybrid consensus-based TrueChain tends to rely on POW consensus for random node selection, instead of using the slow chain mechanism to ensure security like Thunder.Although TrueChain has released dozens of Dapps, the number of its addresses (including active ones)and transactions is small. After the mainnet is launched, the project has run out of short-term bullish factors, which, plus the underdevelopment of its ecosystem, leads to a price slump within a short period of time. It will take some time for investors to regain confidence.

Для расчетов виртуальными деньгами используется только их номер, поэтому криптовалюта и не нуждается в реальном выражении. Цифровые платежные средства защищены криптографическим кодом, что делает их более надежными в сравнении с «настоящими» деньгами. А вследствие абсолютной децентрализации эмиссии виртуальных монет, их нельзя ни подделать, ни запретить.

^ Chan, Edwin. "China Plans to Ban Cryptocurrency Mining in Renewed Clampdown". www.bloomberg.com. Retrieved 10 April 2019. While China was once home to about 70 percent of Bitcoin mining and 90 percent of trades, authorities have waged a nearly two-year campaign to shrink the crypto industry amid concerns over speculative bubbles, fraud and wasteful energy consumption.

Though transaction fees are optional, miners can choose which transactions to process and prioritize those that pay higher fees.[82] Miners may choose transactions based on the fee paid relative to their storage size, not the absolute amount of money paid as a fee. These fees are generally measured in satoshis per byte (sat/b). The size of transactions is dependent on the number of inputs used to create the transaction, and the number of outputs.[7]:ch. 8

As with other cryptocurrencies, the validity of each ether is provided by a blockchain, which is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[30][31] By design, the blockchain is inherently resistant to modification of the data. It is an open, distributed ledger that records transactions between two parties efficiently and in a verifiable and permanent way.[32] Unlike Bitcoin, Ethereum operates using accounts and balances in a manner called state transitions. This does not rely upon unspent transaction outputs (UTXOs). State denotes the current balances of all accounts and extra data. State is not stored on the blockchain, it is stored in a separate Merkle Patricia tree. A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend ether. These can be generated through BIP 39 style mnemonics for a BIP 32 "HD Wallet". In Ethereum, this is unnecessary as it does not operate in a UTXO scheme. With the private key, it is possible to write in the blockchain, effectively making an ether transaction.

If the private key is lost, the bitcoin network will not recognize any other evidence of ownership;[36] the coins are then unusable, and effectively lost. For example, in 2013 one user claimed to have lost 7,500 bitcoins, worth $7.5 million at the time, when he accidentally discarded a hard drive containing his private key.[83] About 20% of all bitcoins are believed to be lost. They would have a market value of about $20 billion at July 2018 prices.[84]

Ethereum's smart contracts are based on different computer languages, which developers use to program their own functionalities. Smart contracts are high-level programming abstractions that are compiled down to EVM bytecode and deployed to the Ethereum blockchain for execution. They can be written in Solidity (a language library with similarities to C and JavaScript), Serpent (similar to Python, but deprecated), LLL (a low-level Lisp-like language), and Mutan (Go-based, but deprecated). There is also a research-oriented language under development called Vyper (a strongly-typed Python-derived decidable language).

In October 2015,[62] a development governance was proposed as Ethereum Improvement Proposal, aka EIP, standardized on EIP-1.[63] The core development group and community were to gain consensus by a process regulated EIP. A few notable decisions were made in the process of EIP, such as EIP-160 (EXP cost increase caused by Spurious Dragon Hardfork)[64] and EIP-20 (ERC-20 Token Standard).[65] In January 2018, the EIP process was finalized and published as EIP-1 status turned "active".[62] Alongside ERC-20, notable EIPs to have become finalised token standards include ERC-721[66] (enabling the creation of non-fungible tokens, as used in Cryptokitties) and as of June 2019, ERC-1155 [67] (enabling the creation of both fungible and non-fungible tokens within a single smart contract with reduced gas costs).

В августе 2017 года Ethereum foundation Виталика Бутерина и глава «Внешэкономбанка» Сергей Горьков подписали соглашение о партнерстве, включающее совместную подготовку специалистов в сфере блокчейна. Программы обучения будут реализованы на базе центра компетенций по блокчейну, о создании которого Внешэкономбанк, Ethereum и майнинговая компания BitFury договорились в июне 2017 года[47].
