Diamond 指的是一种设计模式,称为 EIP-2535 Diamonds。这种模式用于构建可模块化和可升级的以太坊智能合约。

对外部世界(如用户界面、其他智能合约和软件/脚本)而言,Diamond 看起来是一个单一的智能合约,具有一个单一的以太坊地址。但在内部,它使用一组称为 Facets 的合约来处理其外部功能,这些 Facets 对外部是隐藏的。

The ERR_OSSL_EVP_UNSUPPORTED error in a React JS application typically arises due to an underlying issue with the version of Node.js and OpenSSL being used. This error is commonly encountered when certain cryptographic algorithms or keys are not supported by the OpenSSL version bundled with the Node.js installation.
Node.js 17 has a new option called –openssl-legacy-provider. This option lets you go back to using the old way of doing things until you can update your code to work with the new rules.
