Everyone, today let's talk about a frequently overlooked issue.

Many people, when mentioning blockchain, get caught up in TPS numbers. But what I want to say is— the real challenge of Web3 is not the chain itself.

Think about it carefully: a DeFi product needs real-time quotes to settle positions, a game relies on external events to trigger item issuance, and insurance contracts require verification of real weather data for claims. All of this information comes from off-chain sources. The problem is: how to ensure that off-chain data isn't tampered with during transmission? How to guarantee timely delivery of data? This is the key to maintaining the system's trustworthiness.

Oracles were created for this reason. And the APRO project is making some practical innovations in this core area.

Old oracle solutions often face a dilemma. Relying on a few nodes compromises decentralization. Or dispersing verification slows things down to an unbearable degree. APRO's approach is quite straightforward—combine efficient off-chain processing with authoritative on-chain verification to find a balance between speed, cost, and trust.

Its method is layered. Complex calculations and data preprocessing are done off-chain, which greatly improves processing capacity and significantly reduces Gas costs. Most importantly, the results and proofs are ultimately anchored on-chain for public verification. In simple terms, it's an "offline accounting, online notarization" approach.

The benefits are visible. For developers, deployment becomes much simpler. User experience can also be noticeably improved.
