Archive
Indexes all blocks, state, and extrinsic data from Substrate-based blockchains into PostgreSQL.
What is Archive?
Substrate Archive is a blockchain indexing engine that runs alongside Substrate-based chains to capture and store all blockchain data in a PostgreSQL database. It enables efficient querying and analysis of historical blockchain data, which is essential for explorers, analytics platforms, and other data-intensive applications.
Developers and teams building blockchain explorers, analytics platforms, or data-intensive applications on Substrate-based chains like Polkadot, Kusama, or Westend.
It provides a reliable, performant indexing solution that operates as a secondary service to Substrate nodes, ensuring data availability without compromising chain performance, using PostgreSQL for structured storage and RocksDB's secondary instance for non-disruptive data reading.
