## Content

The Ethereum Foundation announced that after more than a year of development, it has officially launched the Ethereum Execution Layer Specification (EELS). EELS is a Python reference implementation of the core components of the Ethereum execution client, with a focus on readability and clarity. It is synchronized with the main network, can fill and execute state tests, and is more friendly to programmers. EELS provides a full snapshot of the protocol on each fork, making it easier to understand than EIP and production clients.
