The blockchain and artificial intelligence (AI) landscapes are converging in groundbreaking ways, and one of the most promising developments is the rise of decentralized, verifiable data infrastructure. At the forefront of this movement is Space and Time (SxT), an open-source AI data protocol that has recently attracted strategic investment from OKX Ventures. Backed by Microsoft’s M12 venture fund, SxT is redefining how on-chain and off-chain data can be securely indexed, queried, and cryptographically verified—offering a new foundation for Web3 applications and enterprise solutions alike.
This article explores the significance of OKX Ventures’ participation in SxT, the innovative technology behind Proof of SQL, and how this advancement supports the future of decentralized computing, AI integration, and secure digital asset management.
What Is Space and Time (SxT)?
Space and Time is a decentralized database protocol designed to provide tamper-proof data services for both blockchain-based applications and traditional enterprises. Over the past two years, its core development team has focused on building a robust, scalable, and cryptographically secure data stack that bridges the gap between Web2 and Web3 environments.
Unlike conventional databases that rely on centralized trust models, SxT enables verifiable computing through its proprietary innovation: Proof of SQL. This cryptographic breakthrough ensures that every query executed on the database produces results that are not only accurate but also immutable and publicly auditable.

Since launching its Beta version in March 2023, SxT has seen rapid adoption. The platform now processes over 500,000 queries per month, with cumulative database requests surpassing 5 billion. It serves a growing ecosystem of decentralized applications (dApps) and mainstream businesses seeking reliable, transparent data infrastructure.
Core Technology: Proof of SQL
At the heart of Space and Time’s innovation lies Proof of SQL, a novel cryptographic mechanism that verifies the integrity of SQL-based queries and their underlying data. In traditional systems, users must trust that query results are correct—there’s no way to independently verify whether data has been altered or manipulated.
With Proof of SQL, SxT changes this paradigm. When a query is executed, the system generates a cryptographic proof that confirms:
- The query was run against authentic, unaltered data.
- The computation was performed correctly.
- The result has not been tampered with during transmission.
This means developers and enterprises can integrate SxT into their applications while maintaining full auditability and trustlessness—key principles of decentralized systems.
Moreover, because SxT supports both on-chain and off-chain data sources, it enables hybrid use cases where real-world business data can be securely combined with blockchain records. For example, a DeFi lending platform could verify a user’s off-chain credit history alongside their on-chain collateral holdings—all within a single, cryptographically secured query.
Broad Chain Support and Enterprise Integration
One of the standout features of Space and Time is its extensive support for major blockchain networks. Currently, SxT provides indexing capabilities for leading public chains including:
- Ethereum
- Bitcoin
- ZKsync
- Polygon
- Sui
- Aptos
- Sei
This cross-chain compatibility makes SxT a powerful tool for multi-chain dApps, analytics platforms, and Layer 2 solutions that require fast, accurate access to on-chain data without relying on centralized providers.
Beyond Web3, SxT is also being adopted by traditional enterprises looking to enhance data transparency and compliance. By integrating verifiable computing into existing business models, companies can reduce fraud risks, streamline audits, and build customer trust through provable data accuracy.
Strategic Vision from OKX Ventures
Dora Yue, founder of OKX Ventures, emphasized the transformative potential of Space and Time:
"Space and Time, as a verifiable computing layer for Web3, has pioneered a new cryptographic technology, Proof of SQL, which, combined with a decentralized data warehouse, cryptographically proves that the computations of queries and the data are accurate and immutable."
She further highlighted how SxT’s integration with zero-knowledge (zk) co-processors and large language models (LLMs) opens new frontiers for user experience optimization in sectors like DeFi and GameFi. For instance:
- In DeFi, users can enjoy enhanced self-custody experiences with built-in safeguards against key loss and unauthorized transactions.
- In GameFi, digital asset ownership becomes more secure, reducing incidents of theft or contract manipulation.
OKX Ventures sees SxT as a critical enabler of sustainable innovation in blockchain technology. The team is particularly excited about the upcoming testnet launch, which will allow developers to experiment with verifiable queries, build new applications, and contribute to the open-source ecosystem.

Why This Matters for the Future of Decentralized Data
As AI adoption accelerates across industries, the need for trustworthy data pipelines grows exponentially. Misinformation, data tampering, and opaque algorithms undermine confidence in automated systems. Space and Time addresses these challenges head-on by introducing cryptographic assurance into every data interaction.
By combining decentralized storage, verifiable computation, and AI-ready query interfaces, SxT lays the groundwork for intelligent applications that are not only smart but also honest. Whether it’s an AI agent retrieving market data for trading decisions or a compliance officer auditing financial records, Proof of SQL ensures that what you see is what actually happened.
Furthermore, the collaboration between OKX Ventures and Microsoft’s M12 signals strong institutional confidence in the long-term viability of decentralized data protocols. This kind of cross-industry validation helps drive mainstream adoption and accelerates technological maturity.
