Ethereum verifies Fulu, Gloas and Heze consensus specs in Lean 4
- —Etheorem implements state transition and fork choice logic for Fulu, Gloas and Heze
- —Results are checked against Ethereum's official consensus test vectors
- —The SizzLean library verifies SSZ serialization and Merkle tree properties in Lean 4
- —The project does not replace clients but expands the scope of formal proofs
Why it matters: Reducing the risk of network splits from divergent spec interpretations strengthens Ethereum's reliability ahead of future upgrades.
