According to Foresight News, the Ethereum Foundation has announced the official launch of the Ethereum Execution Layer Specification (EELS) after more than a year of development. EELS is a Python reference implementation of the core components of Ethereum execution clients, focusing on readability and clarity, making it more programmer-friendly and keeping it in sync with post-merge forks. EELS provides a complete snapshot of the protocol on each fork, including the upcoming ones, making it easier to follow than EIPs (which only propose changes) and production clients (which often mix multiple forks in the same code path). The Ethereum Foundation hopes that EELS will become the default way to specify core EIPs.
