Space and Time, a blockchain project backed by Microsoft, has officially launched its public, permissionless mainnet, aiming to provide decentralized, verifiable data infrastructure for crypto applications. Built by MakeInfinite Labs, the platform offers a decentralized database for querying historical, cross-chain, and off-chain data, with indexing capabilities from major networks like Ethereum. Developers can query this data using Space and Time’s Proof of SQL, a sub-second zero-knowledge (ZK) coprocessor that delivers cryptographic proofs alongside every query. This technology addresses the need for secure on-chain application access to user data without compromising security.
