Space and Time’s SXT Chain is now live on testnet, providing verifiable blockchain indexing, a ZK coprocessor, and a decentralized database to deliver ZK-proven data to smart contracts and AI agents.

Space and Time Unveils SXT Chain Testnet at Chainlink SmartCon

Space and Time Labs, the Microsoft-backed company that recently raised a $20 million Series A, announced on Wednesday, October 30th, that SXT Chain, a blockchain built to deliver zero-knowledge (ZK)-proven data to smart contracts, is live in testnet.

In a press release shared with Cryptowisser, Space and Time Labs said SXT, alongside ZKsync, Chainlink, and Microsoft, will power the next generation of DeFi by providing developers with the data, infrastructure, and tools needed to build advanced, data-driven smart contracts.

The team explained that SXT Chain is a blockchain that indexes data from other major blockchains, including Ethereum, ZKsync, and other EVM and Move chains, and stores it across a decentralized network of database nodes. Developers can access, query, ZK-prove, and connect this data back to their smart contract using Proof of SQL, SXT’s sub-second ZK coprocessor for SQL database queries. 

Several projects building the next generation of data-driven DeFi solutions, like Lendvest, an onchain credit scoring protocol in the Chainlink BUILD program, and are already building on SXT.

While commenting on this latest development, Nate Holiday, Co-Founder and CEO of Space and Time, said,

“Our focus from day one at Space and Time has been making smart contracts smarter by connecting them to a verifiable database. We’re thrilled to launch SXT Chain in testnet to empower developers to build more sophisticated applications onchain. Both ZKsync and Chainlink have been pioneers in expanding the capabilities of blockchain technology, and we look forward to continuing to build the next generation of DeFi together with decentralized, ZK-proven database technology.”

Space and Time will leverage ZKsync technology to launch a ZK Chain within the Elastic Chain ecosystem. The ZK rollup will serve as SXT Chain’s smart contract execution layer, enabling devs to deploy Solidity smart contracts on top of SXT easily. Furthermore, the roll-up will include native DeFi apps that handle client payments, staking, and node operator coordination for the network, as well as third-party DeFi apps for liquid staking, derivatives, and data-intensive apps.

Alex Gluchowski, Co-Inventor of ZKsync, stated that,

“It’s exciting to see that Space and Time is helping to grow the Elastic Chain ecosystem and its capabilities through the SXT Chain as well as the custom ZKsync powered roll-up, empowering developers to build more advanced onchain applications secured by ZKsync. We believe ZK is key to scaling Web3, and the launch of SXT Chain advances our shared vision of offering developers sophisticated, data-driven, cross-chain smart contracts.”

SXT will use Chainlink Network to provide developers with a more familiar and lower-cost way to ZK-verify query results run on SXT compared to gas-heavy verification on Ethereum. SXT is also natively integrated with Chainlink Functions. This will ensure that developers can deliver ZK-proven query results directly to their smart contract from SXT. SXT expands the capabilities for developers leveraging Chainlink services by providing a ZK-proven database that acts as a reliable data source for smart contracts delivered by secure Chainlink oracles.

While speaking of this latest development at Chainlink SmartCon, Sergey Nazarov, Co-Founder of Chainlink, said

“We’re excited that Space and Time is integrating Chainlink’s industry-standard services on its SXT Chain, in addition to receiving support through the Chainlink BUILD program. The integration of SXT with the Chainlink Network significantly enhances the toolkit available to developers, providing a novel and secure solution for building scalable, data-driven smart contracts that can interact with onchain and offchain data in a decentralized way.” 

The Space and Time Labs team comprises world-class AI and cryptography researchers who have already made waves across AI, blockchain, and ZK. Microsoft shared in a blog that the M12 portfolio company has been working closely with the Microsoft AI Co-Innovation Lab to accelerate its generative AI tools and make it easier for developers to build apps onchain. 

Kathleen Mitford, CVP of Global Industry Marketing at Microsoft, said

“At Microsoft, we are empowering growth across emerging markets—including blockchain and distributed data. Together, Microsoft Azure and Space and Time will provide developers with the tools they need to build the next generation of blockchain use cases.”

SXT Chain testnet is now live for developers looking to supercharge their apps and smart contracts with a ZK-proven database. 

Space and Time Labs is a leader in decentralized data and zero-knowledge (ZK) technology and the original contributor to SXT Chain. SXT Chain is a blockchain for ZK-proven data, which provides a verifiable, multichain data platform for smart contracts, enterprises, and AI models. SXT Chain is integrated with Space and Time’s Proof of SQL, a sub-second ZK coprocessor that enables smart contracts to process onchain and offchain data at scale, opening up a wealth of powerful new use cases for blockchain technology. 

Meanwhile, Chainlink is the universal platform for pioneering the future of global markets onchain. Chainlink has enabled over $16 trillion in transaction value by providing financial institutions, startups, and developers worldwide access to real-world data, offchain computation, and secure cross-chain interoperability across any blockchain. Chainlink powers verifiable applications and high-integrity markets for banking, DeFi, global trade, gaming, and other major sectors. 

Finally, ZKsync leverages cutting-edge zero-knowledge (ZK) technology to create secure, scalable, and interoperable blockchain solutions. Through its ZK Stack framework, ZKsync enables developers, enterprises, and financial institutions to deploy customizable ZK Chains, forming the Elastic Chain ecosystem. This innovative network offers native, trustless interoperability, enhanced privacy, and unparalleled scalability while maintaining Ethereum’s security. ZKsync’s mission is to bring crypto to the mainstream, empowering millions of developers and billions of users with digital self-ownership and personal freedom.
