ZK data verification comes to smart contracts with Space and Time's public mainnet

Space and Time, a data protocol that connects smart contracts to verifiable data sources, has officially launched its public mainnet.

Key highlights:

* Space and Time, a protocol that connects smart contracts to verifiable data sources, has officially launched its public mainnet.

* Backed by Microsoft and developed by MakeInfinite Labs, the platform is designed to support the next generation of decentralized applications.

* Its flagship feature, Proof of SQL, enables sub-second timeframes for running SQL queries and receiving zero-knowledge proofs verifying the results.

* These verified outputs can then be securely connected back to smart contracts on-chain.

* Mainnet launch follows Blitzar technology and Chainlink integration for a DeFi yield index.

Smart contracts are fundamentally limited in their ability to access external or complex datasets, posing a challenge for building data-rich decentralized finance (DeFi) products, AI agents, or tokenized real-world assets with any meaningful trust guarantees.

Space and Time, a protocol backed by Microsoft and developed by MakeInfinite Labs, aims to solve that issue with its decentralized data infrastructure. The platform indexes and stores data from blockchains like Ethereum, powered by a network of validators.

Through its flagship feature, Proof of SQL, developers can run SQL queries against the dataset and receive zero-knowledge proofs verifying the accuracy of the results within a sub-second timeframe. These verified outputs can then be securely connected back to smart contracts on-chain.

“Prior to Space and Time, on-chain applications had no way to query basic user data from a database of blockchain activity without introducing security risks and tampering. In addition, enterprises had no way to securely connect their cloud databases with smart contracts. Today, we’re thrilled to announce the mainnet launch of Space and Time, which will empower developers to build sophisticated, data-driven on-chain applications secured by cryptographic proofs.” - Scott Dykstra, Contributor #001 at Space and Time

Recently, MakeInfinite Labs' Blitzar technology, a ZK-enabled elastic network, was deployed on the Ethereum mainnet to support the protocol's launch. Additionally, Chainlink served as an integration partner in creating the Chainlink DeFi Yield Index.

The team's goal is to lay the groundwork for decentralized systems that can scale in complexity and reliability.

“At MakeInfinite Labs, we’re focused on building foundational infrastructure to enable the next generation of crypto applications. Contributing core technologies like Proof of SQL and the original architecture of Space and Time is part of that vision. We’re excited to see the ecosystem take this work forward and unlock new possibilities for verifiable, data-driven applications.” - Nate Holiday, CEO of MakeInfinite Labs and a co-founder of Space and Time

Anyone can contribute to the network, whether by running a validator node, supplying datasets, or staking tokens. This decentralized model ensures that the infrastructure remains trustless and resilient while being broadly accessible to developers and enterprises.

Key takeaways:

* Space and Time's mainnet launch brings together various technologies to create a new layer for decentralized applications.

* The platform focuses on providing reliable, zero-knowledge-verified data access to smart contracts.

* As more blockchain projects seek ways to integrate with real-world and off-chain data sources, platforms like Space and Time could play a central role.

* Support from major players like Microsoft and contributions from a seasoned development team position the protocol for the next era of Web3 and AI-driven systems.
