The ingenious solution of a decentralized database backed by cryptographic proof

The Space and Time project does not merely offer a theoretical idea, but a practical solution that is scalable. The solution lies in creating a decentralized database, meaning it is not owned by any single entity, and is managed in a distributed manner across a global network of devices. However, what sets this system apart is the way it validates the data called by the smart contracts. This method is known as Proof of SQL.

What is Proof of SQL?

Simply put, it is a system that allows smart contracts to issue queries (like 'Does this user have more than $1000 in their wallet?') and receive an accurate answer, along with a mathematical proof that demonstrates the answer is 100% correct and was extracted securely, without any tampering.

This proof can be verified directly within the smart contract, without the need to trust any external party. Thus, decentralized applications can base their decisions on real and accurate data without violating the principle of 'zero trust'.

What distinguishes this innovation from others?

The innovation in Proof of SQL is not limited to data accuracy only, but also to its flexibility. The system supports queries in the well-known SQL language, which is the same language used by most databases in the world. This means that developers and companies can use familiar tools to work with this new system without needing to learn complex technologies.

It also supports integration with Web2 data (such as enterprise databases) and Web3 data (such as blockchain), opening new doors for hybrid applications that combine the best of both worlds.

The bridge between Web2 and Web3

One of the most exciting features of the SXT Space and Time project is what is known as Infinite Tables. This feature allows for the linking of traditional data (such as bank transactions or purchase records) with blockchain data (such as transactions or smart contracts), within the same system, and in a completely decentralized manner. This gives applications the ability to leverage real-world data without sacrificing security or privacy.

Imagine, for example, a decentralized lending application that can verify the user's salary from an external source, while at the same time reviewing their activity on a DeFi platform before approving the loan. All of this can be executed automatically and transparently thanks to this technology.
