Historical data providers offer three primary storage formats:
- Era1(Pre-Merge Execution History) - Archive nodes providing execution layer history before The Merge (ETH1).
- Era(Beacon Chain History) - Stores data from the genesis of the Beacon Chain onwards. Can be used by Execution layer clients for history from The Merge onward, including historical block data.
- E2SS(Execution State) - State snapshots for execution clients.
- E2HS(Execution Layer History) - full execution layer history for execution clients, provides data from genesis to latest, headers are accompanied by proofs of canonicalness.
- Erb(Blob) - Era file equivalent for blob sidecars [
⚠️ Under Development ].
