The canonical specification repository for Ethereum's proof-of-stake consensus layer, defining protocol rules for all consensus clients across sequential network upgrades (Phase0 through Fulu and beyond). It also publishes reference test vectors and a Python package for spec building blocks.
Use cases
- implement an Ethereum consensus client
- verify client conformance against consensus reference tests
- understand how Ethereum proof-of-stake protocol changes work across forks
- track upcoming Ethereum network upgrades like Gloas and Heze
- build tooling that parses or simulates the beacon chain protocol
When to choose
- you are building or testing an Ethereum consensus-layer client
- you need authoritative, up-to-date protocol rules and test vectors
- you want to research proposed consensus changes or design rationale
When to avoid
- you need a runnable node or client implementation rather than a specification
- you want execution-layer (EVM) specs, which live in a separate repository
- you need end-user tooling or wallets
