[Перевод] Исчерпывающее руководство по разработке смарт-контрактов на Solidity

Solidity — это статически типизированный язык программирования, ориентированный на контракты и используемый в основном для написания и реализации смарт‑контрактов на блокчейне Ethereum. Создание высококачественных смарт‑контрактов обеспечивает безопасность, надежность и эффективность. В этой статье рассматриваются основные концепции, лучшие практики и примеры создания надежных смарт-контрактов с помощью Solidity.

@cyberfelidae DOCH!

Genauso wie #Shitcoins alla #Bitcoin, #Ethereum & Co. noch weniger Relevanz haben als #wero, #AliPay und #WeChatPay im deutschen #Einzelhandel!

Nur weils alle einem reinwürgen wird's nicht weniger falsch...

"The prosecution’s flailing attempts to navigate around the Blanche memo exemplify the incoherence of the Trump administration’s approach to cryptocurrency enforcement: sweeping regulatory rollbacks that primarily benefit wealthy crypto operators, while simultaneously pushing ahead with aggressive prosecutions of developers like Storm to avoid the appearance of being soft on North Korea or cybercrime more broadly. The result is a prosecution that must somehow prove that Storm failed to implement specific compliance controls, without being able to point to any regulations outlining these controls that he supposedly failed to follow.

With their legal theory in shambles, prosecutors have resorted to tenuous guilt-by-association arguments and mischaracterized evidence. They’ve tried to hold Storm responsible for scams that may not have even touched Tornado Cash, argued that he should be culpable for not helping scam victims in ways that would not have been technically possible, and built a case for intent around chat messages that turned out to be forwarded news inquiries rather than evidence of criminal conspiracy. What remains is less a coherent prosecution than a cautionary tale about the dangers of letting political imperatives drive criminal cases."

@zkat U could create a system 2 make it easier 4 creators 2 accept #Monero (XMR) a truly private #cryptocurrency, #bitcoin & #ethereum r talked about by the media as if theyre private but theyre actually pseudonymous, if u hav the persons address u hav their entire transaction history, but not with monero. Using it there would be no higher authority (except the state) that could enforce regulations on ur sales, & even then it would have to b serious surveillance bc the network itself is opaque

It took #Ethereum 5 years of planning and 2 more years of transition period to move away from proof of work. Meanwhile The Guardian claims it's a "simple switch" for #Bitcoin

theguardian.com/technology/202 The article is 3 years old, still no proof of stake in sight...

Climate groups say a change in coding can reduce bitcoin energy consumption by 99%

It's really fucking sad that #CryptoBros did "solve" that problem with #middleware like #MetaMask.

Yes I know it's a bad example but when there are thousands of #shitcoins on dozens of #blockchains noone there expects to download yet another wallet...

Смарт-контрактов ещё нет, а адреса уже есть: зачем нужен CREATE2 (EIP-1014)

В этой статье я разбираю, как работает CREATE2, чем он отличается от CREATE, зачем нужен в контексте state channels и ERC-4337, и как его можно использовать — от вычисления адресов в Uniswap V2 до взлома Tornado Cash на $1M. Показываю примеры на Solidity и Assembly, а ещё — как на одном и том же адресе можно развернуть два разных смарт-контракта. Да, и такое возможно.
