Space and Time (SxT) has introduced its custom-built compute layer, providing public access to its sub-second zero-knowledge (ZK) prover stack, called Proof of SQL. This ZK-proof system was previously available to a select group of SxT clients in alpha last August.
ZK provers were developed to address privacy concerns, a crucial aspect of cryptographic technology. The core concept of ZK models allows users to demonstrate the validity or truth of data or transactions without revealing additional information.
This technology is considered essential for ensuring secure on-chain interactions for smart contract protocols and end-users, although it has been known to slow down execution at times. SxT co-founder and head of research Jay White, PhD, explained that the Proof of SQL program was developed so that smart contracts and AI agents could query a chain’s activity and off-chain data and receive trustless SQL query results on-chain during a transaction without waiting for long proof times.
The web3 data warehouse stated that its Proof of SQL offers a better-optimized processing architecture for large-scale operations compared to generalized zk-Virtual Machines and co-processors. According to SxT and White, the ZK prover was able to execute queries for over 100,000 row tables in less than one second on a single GPU unit.
