Blockchain is most skilled at one thing — recording; but the hardest thing to understand is one thing — understanding the world outside the chain. APRO was created to fill this gap.
The logic is actually not complicated: it is not about directly inputting raw data into the chain, but rather first creating a "smart gateway". Collecting messy information outside the chain, using AI and other tools to verify it one by one, and then producing a concise and verifiable conclusion that is returned to the blockchain. In this way, smart contracts will dare to place orders, as the data behind them has already been verified.
Architecturally divided into two layers — outside the chain performing heavy work, a group of nodes running verification and processing; inside the chain placing the lightweight final results. This design ensures the system remains secure while not burdened by excessive computations. In other words, APRO transforms the oracle from merely a "data carrier" into a "data advocate."
