2019 год в плане конфиденциальности был достаточно удручающим. Постоянно были слышны новости о взломах, штрафах за нарушение конфиденциальности или о каких-либо правительственных инициативах, которые могут нести угрозу личным данным. Онлайн-конфиденциальность подвергается нападкам со всех сторон. Хакеры нацеливаются на огромные базы данных личной информации, которые хранят крупные корпорации. Добычей хакеров становятся миллионы записей, содержащих личную информацию. […]
Появление криптовалюты — следующий шаг в развитии экономики. Монеты и бумажки — это прошлый век. Их не всегда удобно использовать: с собой можно носить ограниченное количество, самостоятельно отсчитывать и проверять сдачу, их можно потерять или испортить. Электронные деньги — эквивалент бумажных, только управлять ими удобней. С точки зрения государства и бизнеса безналичные расчеты тоже удобны — электронные платежи проходят быстро, дешево, безопасно.
There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem. The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities. The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code.[41]

Ethereum was officially with an unusually long list of founders. Anthony Di Iorio wrote "Ethereum was founded by Vitalik Buterin, Myself, Charles Hoskinson, Mihai Alisie, & Amir Chetrit (the initial 5) in December 2013. Joseph Lubin, Gavin Wood, & Jeffrey Wilke were added in early 2014 as founders." Formal development of the Ethereum software project began in early 2014 through a Swiss company, Ethereum Switzerland GmbH (EthSuisse).[13][14] The basic idea of putting executable smart contracts in the blockchain needed to be specified before the software could be implemented; this work was done by Gavin Wood, then chief technology officer, in the Ethereum Yellow Paper that specified the Ethereum Virtual Machine.[15] Subsequently, a Swiss non-profit foundation, the Ethereum Foundation (Stiftung Ethereum), was created as well. Development was funded by an online public crowdsale during July–August 2014, with the participants buying the Ethereum value token (ether) with another digital currency, bitcoin.

Эфириум – это попытка разработчиков создать блокчейн, который был бы наиболее эффективным и удобным при операциях с денежными средствами. Эта технология позволяет создать алгоритм, с которым множество операций может быть выполнено программно, с помощью майнинга Эфириума на GPU мощностях. Ресурсы сети могут быть использованы при создании игорных сетей, соцсетей, различных договоров, контрактов и т.д.

Another type of physical wallet called a hardware wallet keeps credentials offline while facilitating transactions.[112] The hardware wallet acts as a computer peripheral and signs transactions as requested by the user, who must press a button on the wallet to confirm that they intended to make the transaction. Hardware wallets never expose their private keys, keeping bitcoins in cold storage even when used with computers that may be compromised by malware.[105]:42–45
