Odaily Planet Daily News According to official news, the Ethereum Foundation announced that after more than a year of development, it will officially launch the Ethereum Execution Layer Specification (EELS). EELS is a Python reference implementation of the core components of the Ethereum execution client, focusing on readability and clarity, being more programmer-friendly and keeping pace with post-merge forks.
EELS provides a full snapshot of the protocol on every fork (including upcoming forks), making it easier to follow than EIPs (which only propose changes) and production clients (often mixing multiple forks in the same code path) .
The Ethereum Foundation wants EELS to be the default way of specifying core EIPs, the first place for EIP authors to prototype their proposals, and the best reference for how Ethereum works.
