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 […]

In Ethereum all smart contracts are stored publicly on every node of the blockchain, which has costs.[56] Being a blockchain means it is secure by design and is an example of a distributed computing system with high Byzantine fault tolerance. The downside is that performance issues arise in that every node is calculating all the smart contracts in real time, resulting in lower speeds.[56] As of January 2016, the Ethereum protocol could process about 25 transactions per second.[56] In comparison, the Visa payment platform processes 45,000 payments per second leading some to question the scalability of Ethereum.[57] On 19 December 2016, Ethereum exceeded one million transactions in a single day for the first time.[58]

В целом, Bitcoin лучше справляется с функциями платежного средства. Если вам нужна криптовалюта для покупок или хранения денег, то BTC с этим справится лучше Эфира. Его принимает большее количество сайтов, да и статус цифрового золота говорит сам за себя. Ethereum стоит рассматривать не столько как криптовалюту, а как универсальную платформу по созданию децентрализованных программ на основе смарт-контрактов. То есть, у Эфириума более широкие «полномочия», если можно так выразиться.

The successful miner finding the new block is allowed by the rest of the network to reward themselves with newly created bitcoins and transaction fees.[94] As of 9 July 2016,[95] the reward amounted to 12.5 newly created bitcoins per block added to the blockchain, plus any transaction fees from payments processed by the block. To claim the reward, a special transaction called a coinbase is included with the processed payments.[7]:ch. 8 All bitcoins in existence have been created in such coinbase transactions. The bitcoin protocol specifies that the reward for adding a block will be halved every 210,000 blocks (approximately every four years). Eventually, the reward will decrease to zero, and the limit of 21 million bitcoins[g] will be reached c. 2140; the record keeping will then be rewarded solely by transaction fees.[96]
Ethereum is an open source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. It supports a modified version of Nakamoto consensus via transaction-based state transitions. Ether is a cryptocurrency generated by the Ethereum platform and used to compensate mining nodes for computations performed.[3] Each Ethereum account has an ether balance and ether may be transferred from one account to another.
Получается, что Ethereum – это такая себе блокчейн-пандора с почти неограниченными возможностями по использованию, благодаря своей гибкости, мощности и универсальности. Это действительно так. Иначе бы к ней не проявляли интерес компании вроде Microsoft, IBM, JPMorgan. Волна ICO 2016-2017 – это результат появления Эфириума с его умными контрактами. Большинство этих краундфандинговых проектов выпускают токены стандарта ERC-20 (эфирирум классик) и используют именно блокчейн Ethereum.

Как Zcash отличается от Bitcoin

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).

Как купить Bitcoins на Blockchain

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.

Cameron and Tyler Winklevoss, the founders of the Gemini Trust Co. exchange, reported that they had cut their paper wallets into pieces and stored them in envelopes distributed to safe deposit boxes across the United States.[107] Through this system, the theft of one envelope would neither allow the thief to steal any bitcoins nor deprive the rightful owners of their access to them.[106]

Izabella Kaminska, the editor of FT Alphaville, has pointed out that criminals are using Ethereum to run Ponzi schemes and other forms of investment fraud.[68] The article was based on a paper from the University of Cagliari, which placed the number of Ethereum smart contracts which facilitate Ponzi schemes at nearly 10% of 1384 smart contracts examined. However, it also estimated that only 0.05% of the transactions on the network were related to such contracts.[69]
