Crypto startup Space and Time, based in California, has made waves in the blockchain industry with the launch of their advanced zero-knowledge (ZK) prover, Proof of SQL. This innovative technology is designed to significantly enhance on-chain transaction efficiency, a crucial development in the world of cryptocurrency.
Previously only available to a select few clients during its alpha phase last August, Proof of SQL is now open to the public, marking a major milestone for the company. ZK provers are essential for maintaining privacy in cryptographic systems by allowing users to verify data or transactions without revealing additional information. However, they have been criticized for slowing down transaction execution.
Dr. Jay White, co-founder and head of research at Space and Time, explained the groundbreaking innovation behind Proof of SQL. The team has pioneered sub-second ZK-proofs, enabling smart contracts and AI agents to query a chain’s activity and off-chain data, receiving trustless SQL query results on-chain during a transaction without the typical 30-minute proof times.
Moreover, Proof of SQL offers a more optimized processing architecture for large-scale operations compared to traditional zk-Virtual Machines (zkVMs) and co-processors. With the ability to process queries involving over 100,000 rows in less than a second using a single GPU unit, this technology promises faster and more extensive task execution when integrated into zkVMs on blockchains like Ethereum (ETH).
The launch of this new ZK prover represents a significant advancement in blockchain technology, with the potential to revolutionize DeFi and on-chain transactions. By reducing query times and enhancing processing efficiency, Proof of SQL is poised to make a lasting impact on the industry.
In related news, Ethereum co-founder Vitalik Buterin has proposed using ZK technology for implementing “likes” on Farcaster, an Ethereum-based decentralized social media platform. This further demonstrates the versatility and potential applications of ZK technology in various blockchain projects.
Overall, the introduction of Proof of SQL by Space and Time showcases the ongoing innovation and progress in the crypto space, paving the way for more efficient and secure transactions on the blockchain.
