Space and Time, a blockchain project supported by Microsoft, has launched its public, permissionless mainnet to bring zero-knowledge (ZK)-proven data infrastructure to crypto applications.

Built by MakeInfinite Labs, Space and Time offers a decentralized, verifiable database for smart contracts to query historical, crosschain and offchain data, according to a news release shared with Cointelegraph.

The platform indexes data from major networks like Ethereum and makes it accessible through a decentralized network of validators. Developers can query this data using Space and Time’s Proof of SQL — a sub-second ZK coprocessor that delivers cryptographic proofs with every query.

“Prior to Space and Time, onchain applications had no way to query basic user data from a database of blockchain activity without introducing security risks and tampering,” said Scott Dykstra, co-founder at Space and Time.

He added that developers can now build onchain apps with built-in security, using cryptographic proofs to connect cloud databases to smart contracts.

Major builders already on Space and Time

Dykstra said prominent financial institutions, major cloud providers like Microsoft Azure and Google BigQuery, and some of the biggest projects in crypto, including Chainlink, Sui and ZKsync, have either integrated or are building with tools or data services in the Space and Time ecosystem.

He also told Cointelegraph that SXT, the native utility token for Space and Time, is planned for release on May 8.

“Space and Time mainnet is permissionless, and we encourage the community to join the network as validators and delegated stakers,” Dykstra said.

He added that the testnet had more than 30 validators worldwide, including in the US, Europe, Asia and Latin America.

MakeInfinite Labs (previously Space and Time Labs), the original contributors to Space and Time, held a strategic round led by Microsoft in 2022. They also supported the follow-on Series A round in 2024.

MakeInfinite Labs has also contributed to other projects within the crypto space, including Blitzar and the Chainlink DeFi Yield Index.
