Blockchain is incredibly powerful, but it has a fundamental limitation — it’s essentially "blind." Smart contracts only execute code instructions and have no awareness of the outside world. What is the current price of Bitcoin? Who won the sports event? Is a certain contract valid? These questions are all beyond their reach.

This wall blocks almost all blockchain developers. They need external data, but more critically — how to ensure that this data is trustworthy.

APRO was born to address this pain point. Founders Leo and Simon are experienced developers who are very familiar with the problems of traditional oracles: slow operation speed, high usage costs, and susceptibility to manipulation. What troubles them even more is that the entire decentralized finance ecosystem is built on these unreliable data sources. They ask themselves, how can such an architecture be truly trustworthy?

So they decided to rethink the essence of oracles: can they build a truly decentralized system that also has intelligent data processing capabilities? Not just transmitting price data, but transforming complex real-world information — such as proof of file ownership, video content extraction, image recognition results — into verifiable on-chain data?

The idea is bold, but execution must be step-by-step. In early 2024, the team was still repeatedly adjusting the architecture in a small office, debating over the consensus mechanism. They struggled to explain to everyone: what we’re doing is far more than just a "market quote system."

The final product is called "Oracle 3.0." The APRO network has the ability to understand unstructured data — capable of recognizing PDF ownership information, extracting key video data, and then converting it into trusted facts recognized by the blockchain. Compared to traditional oracles that can only handle simple price information, this is a completely different level of evolution.
