This page contains a community-maintained list of Ethereum historical data endpoints, including Era1, Era, E2SS files, and torrents.

⚠️ This list should not be treated as a single source of truth for these endpoints, or the data they provide. It is a community-maintained list, and as such, some endpoints listed here may not be up to date, or may not provide the data they claim to be providing.

Historical data providers offer three primary storage formats:

• Era1 Spec - Execution layer historical block data before The Merge.
• Era Spec - Consensys layer historical block data from The Merge onward.
• E2SS Spec - State snapshots for execution clients.
• Erb Spec - Era file equivalent for blob sidecars [ ⚠️ Under Development ].

This registry is designed to reduce reliance on centralized providers by creating a publicly accessible, decentralized list of historical data sources. It aligns with EIP-4444 and Portal Network efforts to ensure that Ethereum clients can obtain block history beyond what traditional p2p sync provides. Additionally, some providers may distribute historical data through torrents, offering alternative sync options.

Type indicates whether the endpoint is a torrent or web endpoint.

If you’d like to add your endpoint to the list, please read the documentation.
