Blockchain is like a perfectionist accountant—it enforces rules with zero tolerance for error, never makes a mistake in its ledgers, and records every transaction permanently. But here’s the problem: these "bookkeepers" are complete information islands, totally blind to the outside world.

This is an underrated crisis in the crypto world: smart contracts can automatically trigger loan repayments, but have no idea if the borrower's collateral (such as tokenized real estate) just dropped by 50%. No matter how smart on-chain code is, it can’t access real-world prices, weather data, or sports results off-chain.

APRO doesn’t aim to be just another "ultra-fast price feed" gimmick project. What it wants to solve is the longstanding oracle problem—how to make blockchains reliably "see" the real world, instead of being fed manipulated, fake data. For DeFi to truly take off, this fundamental infrastructure gap must be filled.
