Article Summary
Space and Time, the Microsoft-backed blockchain for zero-knowledge (ZK)-proven data, has launched its public, permissionless mainnet. The platform is designed to deliver ZK-proven data to smart contracts, enabling a new generation of data-driven crypto applications. It indexes data from other major blockchains and stores it across a decentralized network of database validators. Developers can access, query, and connect this data back to their smart contracts using Proof of SQL, Space and Time’s sub-second ZK coprocessor for SQL database queries.
What This Means for You
- Developers can now build sophisticated, data-driven onchain applications secured by cryptographic proofs using Space and Time’s ZK-proven data.
- Enterprises can securely connect their cloud databases with smart contracts, opening up new possibilities for data-driven decentralized applications.
- Smart contracts can now query the full history of Ethereum and beyond, enabling a new wave of onchain innovation, including dynamic financial instruments, data-rich AI agents, and tokenized real-world systems.
- Space and Time’s decentralized database network provides a trustless layer for complex data retrieval, enhancing the security and reliability of onchain applications.
