There is a cruel paradox in the Web3 world: blockchain has established a perfect trust record system, yet it turns a blind eye to everything outside the chain. Imagine a genius with an extraordinary memory, but blind — that’s the core of the problem.

This also explains why oracles are not optional but essential for blockchain. Without oracles, DeFi protocols would be blindly liquidating, rare drops in games would become black boxes, and trillions of dollars worth of real-world assets would be permanently locked outside the chain.

APRO’s goal is to equip this blind world with a pair of verifiable eyes.

**From Transporting to Creating**

Traditional oracles are straightforward: copying price data from location A to smart contracts at location B. But what if the source data itself is falsified? That’s where the problem arises.

What sets APRO apart is — it doesn’t just transport data, it produces trust.

In terms of architecture, APRO has learned from news agencies: reporters gather raw data from hundreds of independent sources, the editorial team uses machine learning for cross-validation and anomaly detection, and finally, a fact-checking team (on-chain arbitration layer) makes the final decision when disputes arise. The collection, validation, and arbitration processes upgrade APRO from a simple data pipeline to a truth infrastructure.

**Subscription or Peer-to-Peer**

The method of data delivery also matters. Different DeFi scenarios require different data supply models — high-frequency trading demands millisecond updates, while lending protocols may only need periodic snapshots. APRO offers more flexible options in this regard.

The core logic is quite clear: verifiability is the foundation of trust, and trust is the fuel that keeps Web3 running.
