Space and Time launches an enterprise platform for verified AI calculations on private data

Space and Time announced Space and Time Enterprise on November 9, letting companies run AI tools over private databases and prove the results are correct without handing over the underlying records. The platform extends its Proof of SQL work using zero-knowledge proofs and needs no blockchain, GPUs or specialized hardware, running on ordinary laptops and servers.

Space and Time, a blockchain data project backed by Microsoft's venture arm, announced Space and Time Enterprise on Monday, a platform that lets companies run AI tools over private data while proving the calculations are correct without exposing the underlying records.

The mechanism is a cryptographic proof attached to SQL query results: a query runs against the customer's database, and the system generates a verifiable receipt showing the answer was computed correctly from the data on file, so AI applications and auditors can check the result without touching the database.

The product extends the project's Proof of SQL technology and adapts it for private enterprises using zero-knowledge proofs, which let one party convince another that a statement is true without revealing the information behind it.

The strategic choice is what the enterprise edition leaves out: it does not require a blockchain or a network of nodes for independent verification, and it runs on ordinary laptops and servers with no GPUs or blockchain-specific hardware, while data stays under the customer's control.

Nate Holiday, CEO of MakeInfinite Labs, which develops the technology, framed the launch around minimum access, saying AI agents do not need unrestricted access to the records behind every calculation.

Space and Time operates under SXT Chain, whose mainnet launched in May 2025, and Microsoft's M12 has put $20 million into the project since 2022. Its SXT token covers staking, payments and access control within the chain, and the project counts Circle and Coinbase among its partners.

The roadmap points to a mainnet v2 focused on securing offchain data for tokenized finance, plus a deeper Microsoft Fabric integration aimed at real-time verifiable blockchain data.

Three things are worth watching: whether named enterprise customers appear, whether the mainnet upgrade lands on schedule, and how deeply the Fabric integration ends up embedding Space and Time inside a platform many businesses already use.

Why it matters

Dropping the blockchain requirement is a practical concession to win conventional enterprise buyers, and it removes a major source of deployment friction. The test is whether named customers appear and whether verifiable computation becomes a routine part of enterprise AI auditing.
