A new high-performance ZK prover has been released by California-based crypto business Space and Time to boost defi growth and on-chain transactions.
A custom-built compute layer called Space and Time (SxT) made its sub-second zero-knowledge (ZK) prover stack, known as Proof of SQL, publicly available.
A small number of SxT clients were first given access to the ZK-proof system in alpha last August. ZK provers are essential to cryptography because they meet privacy requirements.
Users can prove that data or transactions are accurate or legitimate without disclosing further information according to the basic tenet of ZK models.
Vitalik Buterin of Ethereum and other web3 developers have emphasized the significance of ZK stacks in creating dependable decentralized financial (defi) ecosystems.
The technology is seen to be essential for guaranteeing end users’ and smart contract protocols’ safe on-chain interactions. ZK proofs, however, have been known to cause execution to lag occasionally.
The Proof of SQL program was created “so that smart contracts and AI agents can ask questions about a chain’s activity, as well as off-chain data, and receive back trustless SQL query results on-chain during a transaction without having to wait for 30 minute proof times,” according to Jay White, PhD, co-founder of SxT and head of research.
Regarding large-scale operations, the web3 data warehouse claims that its Proof of SQL offers a more optimal processing architecture than generalized zk-Virtual Machines and co-processors.
SxT and White claim that the ZK prover used a single GPU to process queries for more than 100,000 row tables in less than a second. The model can be included into zkVMs on blockchains such as Ethereum (ETH) for larger workloads and quicker speeds.
