Space and Time, a leading platform for blockchain, AI, data, and zero-knowledge (ZK), has announced a significant milestone today. Their ZK prover for SQL queries, known as “Proof of SQL,” has achieved sub-second proving speeds for analytic queries against one million rows of data.
Powered by NVIDIA, Space and Time’s prover achieves sub-second speed
Space and Time’s team officially stated that they have successfully reached sub-second proving speeds for their SQL prover. This achievement was made possible through the integration of NVIDIA computation power, marking a major advancement in ZK encryption for external data.

As of May 2025, Space and Time’s prover stands out as the fastest on the market for proving SQL queries with zero-knowledge (ZK) capabilities.
Proof of SQL is a cutting-edge ZK circuit designed to validate the accuracy and integrity of SQL database queries. This prover can be seamlessly integrated into any SQL database, whether centralized or decentralized, and is already being utilized by top Web3 apps, AI protocols, financial institutions, and enterprises.
Dr. Jay White, Cofounder and Head of Research at MakeInfinite Labs and the mastermind behind the Proof of SQL protocol, emphasizes the significance of this release for the Web3 data logistics ecosystem:
Space and Time is leading the way in developing fast and practical ZK solutions for real-world workloads and applications. Our partnership with NVIDIA and utilization of their technology are crucial in realizing this vision. We are excited about the progress of Proof of SQL and are eager to continue collaborating with the NVIDIA team to drive the next wave of AI and blockchain applications, empowered by ZK.
Proof of SQL leverages NVIDIA’s accelerated computing and its proprietary GPU acceleration framework to process large volumes of data more efficiently than any other existing solution.
Proof-of-SQL tool now available for developers on GitHub
Developers and enterprises interested in incorporating ZK into their databases and developing cutting-edge applications with verifiable data can now access Proof of SQL on GitHub.
In the latest benchmarks shared on GitHub, the protocol demonstrates its ability to execute analytic queries on tables with one million rows in under a second on NVIDIA GPUs.
Space and Time recently launched its mainnet on May 8, 2025, and activated SXT ERC-20 token staking. Prior to this, the protocol’s founding entity secured $50 million in funding from Microsoft’s VC arm.
