Proof of SQL℠

Proof of SQL is the novel cryptography developed by Space and Time that allows the data warehouse to generate a SNARK cryptographic proof of SQL query execution, proving that query computation was done accurately and that both the query and the data are verifiably tamperpoof.

Proof of SQL enables you to run trustless queries against both on-chain and off-chain data and connect the result back to your smart contracts on-chain. This essentially allows smart contracts to ask questions about data on their own chain, data on other chains, and off-chain data from any source. Space and Time is making smart contracts smarter by giving them access to verifiable off-chain data and compute, enabling new use cases for Web3 and enterprises, such as:

  • Decentralized trading: Verifiable proof of trade executions, liquidity pool dynamics, and loan repayments
  • Decentralized lending: Proof of interest calculations and loan distributions
  • Private data sharing: Verifiable exchange of encrypted data without revealing the data itself


Coming soon: Proof of SQL is currently in alpha, and the API specs are not publicly available. To request access, join the Space and Time beta and reach out to the team.
