What Is Space and Time (SXT)?

Key Takeaways

Space and Time (SXT) is a decentralized protocol for verifiable data processing using zero-knowledge (ZK) cryptography.

It enables smart contracts and AI agents to access tamperproof, SQL-based data without relying on centralized services.

The core innovation, Proof of SQL, allows off-chain query results to be proven on-chain using zero-knowledge proofs.

SXT is the governance and utility token that powers the ecosystem and rewards node operators.

Introduction

Access to accurate, tamperproof data is essential for decentralized applications (DApps), smart contracts, and AI agents operating in trustless environments. Traditional data systems often rely on centralized sources, which can limit transparency and introduce vulnerabilities. To address this challenge, new decentralized data infrastructure is emerging to bridge the gap between Web2-scale systems and blockchain networks.

What Is Space and Time?

Space and Time is a decentralized data platform that enables verifiable off-chain data processing for on-chain applications. It allows developers to execute SQL queries on external datasets and validate those results on-chain using Proof of SQL, a zero-knowledge protocol that ensures cryptographic integrity.

The platform supports use cases across DeFi, AI, and enterprise applications by allowing DApps and AI agents to securely access and act on large volumes of data. Built with support from Microsoft, Space and Time is designed for multichain compatibility and currently supports networks such as Ethereum and Base.

Key components include:

Proof of SQL: A ZK-proof system for off-chain SQL computation.

Decentralized data warehouse: For ingesting and storing structured data.

Multichain compatibility: Supporting Ethereum, Base, and other networks.

Node infrastructure: For decentralized query processing and validation.
