Verifiable, decentralized data warehouse with cryptographic SQL proofs
Last updated: July 2026
Space and Time (SxT) is a decentralized data warehouse that indexes blockchain data and, distinctively, can prove that query results are accurate and untampered using its Proof of SQL technology — cryptographic proofs that let smart contracts trust off-chain query results. This verifiability is its key differentiator: normally, when a smart contract needs the result of a complex data query (say, a user's historical trading volume for a reward), it has to trust an off-chain source; Space and Time's Proof of SQL generates a cryptographic proof that the SQL query was executed correctly against real data, so the result can be trusted on-chain. It combines indexed multi-chain data with a SQL interface and this proof layer, targeting use cases where verifiable off-chain computation matters. It has a token and enterprise offerings. The trade-offs: its verifiable-query technology is powerful but advanced and aimed at specific use cases (most apps that just need data don't require cryptographic proofs); it's a newer, more specialized platform; and the proof layer adds conceptual and practical complexity. But for developers building applications where trustless, verifiable query results matter — trust-minimized rewards, on-chain decisions based on off-chain data, verifiable analytics — Space and Time offers a genuinely novel capability that standard indexers can't, making it a distinctive and forward-looking entry in the blockchain data landscape.
