zkVerify delivers faster, cost-effective SQL data verification with enhanced security and privacy for data-intensive applications.

zkVerify, the modular blockchain for ZK-proof verification, has launched a decentralized proof verifier for Space and Time's Proof of SQL ZK coprocessor on SXT Chain. By leveraging zkVerify’s verification of SXT proofs, organizations can verify their ZK-proven SQL queries faster and more efficiently compared to Ethereum verification.

Space and Time’s Proof of SQL ZK coprocessor employs zero-knowledge proofs to validate SQL queries run against data stored on SXT Chain, its recently launched blockchain for ZK-proven data. zkVerify functions as a decentralized proof verifier within this system for Space and Time’s Proof of SQL, offering fast, on-chain confirmation of query accuracy without relying on any central authority. 

Traditional smart contracts face limitations in accessing external or historical transaction data, which restricts their functionality. Space and Time’s SXT Chain addresses this by acting as a decentralized database that aggregates data across major blockchains—Ethereum, ZKsync, Bitcoin, Sui, Aptos, and Polygon, and proves it back to smart contracts with Proof of SQL. This setup enables trustless, cross-chain data processing, allowing smart contracts to efficiently query, analyze, and utilize data.

As concerns about data manipulation and AI-generated content increase, Space and Time, coupled with zkVerify’s technology, allow organizations to prove the integrity of their data without exposing the underlying information. For example, financial institutions can verify transaction records, healthcare providers can ensure patient data remains accurate, and AI applications can confirm the authenticity of their outputs—all using mathematical proofs instead of relying on trust alone.

Launched in October 2024, Space and Time’s SXT Chain testnet lets developers query historical data from major blockchains like Ethereum, Bitcoin, and Polygon, generating mathematical proofs that ensure data integrity. In August 2024, Space and Time raised $20 million in Series A with funding from Microsoft’s M12 Venture, Framework Ventures, Lightspeed Faction, Arrington Capital and Hivemind Capital.

How does it work?

Using zero-knowledge proofs to create a proof of correct computation, like Proof of SQL, has three essential elements: the actual data, the creation of the proof, and the verification of that proof. These components must work together in a rapid, straightforward, decentralized, and permissionless manner to enable a seamless, trustless system.

The Proof of SQL mechanism operates by generating a mathematical hash of a SQL table’s content, which is then used to generate a ZK proof that neither the table nor the queries run against have been tampered. Space and Time’s high-speed ZK coprocessor creates these proofs, and zkVerify is used to validate them using their public, decentralized blockchain. This enables businesses and decentralized applications to share data or query results with provable SQL database integrity, verifiable by anyone without relying on centralized entities.

In its role as the proof verifier, zkVerify adds a crucial layer of trust and security, ensuring that each SQL query validated by Proof of SQL on the SXT Chain is accurate and tamper-proof. With zkVerify, data queries and results can be trusted across the network, empowering advanced decentralized applications, such as DeFi platforms, data-intensive analytics, and Solidity smart contracts deployed directly on SXT’s ZK rollup. This integration amplifies the potential for on-chain applications by enabling access to verified, cross-chain data in real-time, paving the way for more sophisticated decentralized services.

Rob Viglione, CEO of Horizen Labs, the development studio behind zkVerify, said: "Zero-knowledge proofs redefine trust in digital systems by providing mathematical assurance of data integrity without exposing sensitive information. This technology allows businesses to verify the accuracy of their data transparently and securely, without relying on third-party auditors. For sectors like finance and healthcare, it’s a paradigm shift from 'trust us' to 'we can prove it,' bringing a new level of confidence to data handling."
