Chainlink Standard Optimizes ZK Proof Verifications for Space and Time’s Proof of SQL on SXT Chain

• Space and Time launched Proof of SQL on testnet, a ZK-proof tool enhancing blockchain queries with accuracy and cost efficiency.
• Sergey Nazarov emphasized Chainlink’s role in verifying ZK proofs, making Ethereum integration scalable and affordable for developers.

Space and Time (SXT) has unveiled a game-changing milestone in its partnership with Chainlink. The collaboration has successfully launched the Proof of SQL integration on testnet, marking a significant leap in decentralized data management and blockchain development.

.@SpaceandTimeDB has integrated the #Chainlink standard on SXT Chain testnet to help optimize ZK proof verifications for its Proof of SQL solution.

At the recently concluded Chainlink SmartCon event, SXT introduced the SXT Chain, a blockchain specifically designed for Zero-Knowledge (ZK) proof-secured data. This innovative platform functions as a decentralized database, enabling developers to retrieve data from on-chain and off-chain sources with unmatched security. The star feature, Proof of SQL, takes center stage, ensuring developers can query data securely, efficiently, and without compromise.

Proof of SQL isn’t just any tool—it’s a ZK coprocessor designed to validate SQL queries against data stored on the SXT Chain. Indexing and signing blockchain data guarantees the accuracy and integrity of both SQL computations and underlying information. This technology is a game-changer, offering developers trust and reliability in the otherwise complex and error-prone world of blockchain queries.

Why Chainlink’s Role is Vital?

Verifying ZK proofs on Ethereum’s mainnet, while secure, has historically been an expensive endeavour. This is where Chainlink’s industry-standard services step in, making ZK-proof verification more efficient and cost-effective. By adopting Chainlink’s standards, Proof of SQL optimizes its operations, reducing the gas-heavy methods traditionally used on Ethereum.

Chainlink’s influence doesn’t stop there. Sergey Nazarov, Co-Founder of Chainlink, expressed his enthusiasm for the collaboration:

We’re excited that Space and Time is integrating Chainlink’s services on its SXT Chain […] enhancing the toolkit for developers to build scalable, data-driven smart contracts interacting with onchain and offchain data.

This partnership doesn’t just enhance developer tools; it redefines how developers interact with ZK proofs and blockchain databases. With this integration, SXT delivers a trusted and familiar platform for building on-chain solutions, all while maintaining cost efficiency.

Seamless Query Processing for Developers

Here’s how the process works: A developer initiates a call through Chainlink Functions to the SXT Chain. SXT responds by providing both the requested query result and a ZK proof. Chainlink then steps in to verify this proof using its robust consensus mechanisms. Once verified, the result is returned to the client—eliminating the need for resource-intensive Ethereum-based verification.

The seamless integration doesn’t just streamline processes; it sets a new benchmark for reliability and innovation. The collaboration ensures developers can expand their on-chain projects without the burden of high verification costs, unlocking new possibilities for blockchain applications.

SXT also deepens its integration with Chainlink Functions. This feature allows developers to bring ZK-proven query results directly into their smart contracts, enhancing the scope of what’s possible within decentralized ecosystems. By acting as a ZK-proven database backed by Chainlink oracles, SXT becomes an invaluable tool for developers building the next generation of decentralized applications.
