This proposal by Subsquid Lab Official seeks funding for ongoing development and maintenance of Subsquid Archives and the Giant Squid API, vital components of Polkadot and Kusama data infrastructure. Archives provide GraphQL access to on-chain data for various parachains, supporting projects like Polkassembly and Talisman. The ArrowSquid release enhances real-time processing and decentralizes Archives. In Q3 2023, Subsquid served over 1.46 billion queries, indicating significant usage.
