Space and Time Launches Private Data Verification for AI Applications and Auditors

Space and Time launched an enterprise platform Monday, Nov. 9, that lets AI applications and auditors verify calculations from private business records without receiving the underlying data.

Space and Time Enterprise extends the company’s Proof of SQL technology into software that businesses can run on their own servers. A database query returns a result and a cryptographic proof. A recipient checks the proof against a trusted commitment to the data used in the calculation.

That check can establish whether the query produced the stated result from the committed records. It cannot establish whether those records were accurate when entered. The source records remain in the business’s environment, although the query result is returned in readable form.

Space and Time named Maple Finance, Indomobil, Trenez and The Data Foundation as launch partners. It lists collateral checks, asset valuations, financial reporting and audits as potential uses. The company did not provide figures showing how extensively the partners have deployed the platform.

“Privacy is a prerequisite for enterprise adoption,” said MakeInfinite Labs CEO Nate Holiday, whose company originally developed Space and Time.

Businesses can run the software without connecting to a blockchain or using specialized GPU hardware. Keeping the source records in a company’s systems lets it share a calculation for checking without handing over the underlying database. Recipients can still read the result the query returns.

The software’s published HTTP interface has no built-in authentication or authorization. A business exposing that interface beyond a local installation would need separate access controls. The cryptographic proof checks a calculation; it does not control who can submit a query.

The enterprise product is separate from SXT Chain, where Space and Time (SXT) is used for transactions. Because the software can run without a blockchain, installing it does not itself establish SXT use or new demand for the token.

Proof of SQL was previously integrated with Google Cloud’s BigQuery. M12, Microsoft’s venture fund, led a $20 million funding round for Space and Time in 2022.
