what's Provably?

Provably is a protocol for verifiable databases and SQL queries tailored for distributed systems such as blockchains, traditional databases, and AI infrastructures. It allows data owners to preprocess private datasets once and then generate compact cryptographic proofs—under 1.5 KB using KZG polynomial commitments—for the correctness and completeness of SQL query responses. This approach outperforms Merkle-tree based methods in efficiency and supports privacy budgets for data pricing, enabling secure querying without revealing underlying data. Key applications include powering DeFi networks with verifiable on-chain data, automating compliance in agentic commerce, and facilitating multi-agent AI workflows with provable results on private information. Provably's V2 introduces QEDB, a SNARK-free protocol for faster verification, and integrates with blockchains for expressive queries. It bridges off-chain databases (e.g., Postgres) to on-chain verification, fostering collaboration over verifiable data across ecosystems.
