Etheorem: Lean 4 Consensus-Spec Proofs
A novel approach to the spec, a single artifact that can we run, test, and prove. Contributions included completeness theorem for merkle branch check widely used in consensus (deposits, lightclient sync, and PeerDAS sampling), protocol arithmetic and invariants proofs, and various spec model improvements (including modeling Heze fork with FOCIL).
