Space and Time rolls out enterprise AI verification that ditches the blockchain

Space and Time unveiled Space and Time Enterprise on Monday, a platform that lets companies run AI tools over private databases while keeping the raw records walled off. The Microsoft-backed project says businesses can prove a calculation came out right, and outsiders — AI apps, auditors, whoever — can verify that result without ever touching the database itself.

The machinery underneath is Proof of SQL, the project's existing tech, now retooled for private enterprises. It attaches cryptographic proofs to SQL query results, the standard language businesses use to pull answers out of their data, so the answer arrives with a mathematical receipt. Zero-knowledge proofs do the heavy lifting. Nate Holiday, CEO of MakeInfinite Labs, the developer behind Space and Time, told Decrypt that AI agents don't need unrestricted access to the records behind every calculation, framing the launch around minimal access.

Notably, the enterprise edition skips the blockchain entirely. It runs on ordinary laptops and servers — no GPUs, no node network — and customers keep control of their data. Space and Time operates under SXT Chain, which launched its mainnet in May 2025, and carries a native SXT token used for staking, payments and access control. Microsoft's M12 venture arm has put $20 million into the project since 2022, and partnerships with Circle and Coinbase have helped pull in enterprise and institutional interest.

The roadmap holds the next crypto-specific catalysts: a mainnet v2 expected by late 2025, built to better secure offchain data for tokenized finance, plus a deeper integration with Microsoft Fabric aimed at delivering real-time verifiable blockchain data. Whether the enterprise product feeds activity back into the SXT token ecosystem is a question the announcement leaves open.
