影子Reth：影子日志的执行扩展 - @emhsia - 前沿

Emily, co-founder and CTO of Shadow, introduced ShadowRef, a tool that enables the addition of gasless logs, known as Shadow Logs, to existing smart contracts without increasing gas costs for users. Shadow Logs are generated in an off-chain execution environment, allowing developers to access deeper data coverage and simplify data pipelines without redeploying contracts. ShadowRef, an open-source implementation, allows users to generate these logs within their own nodes, promoting decentralization and verification. The architecture includes a shadow configuration, a shadow executor for block re-execution, and a custom RPC endpoint for fetching logs. Future developments aim to enhance data connectivity and create a decentralized registry for shadow contracts, enabling easier access to pre-written contracts for developers.
