Have you ever wondered what truly supports the money you earn through yield farming, lending, and mining in DeFi?

Many say it's code or project teams, but that's not quite right. The real support comes from a group of invisible "data transporters"—and among them, the most critical are oracles like APRO.

Sounds a bit abstract? Think of it this way: if real-time data systems like this fail in 2026, the current prosperity you see in DeFi would instantly turn into a naked run.

**The changes in the BTC ecosystem say it all**

Remember the on-chain data from early 2024? Back then, you received a price quote, and the market had already moved. Using "Nokia-speed" internet for high-frequency trading—that's how it was.

And in 2025? BTC instant borrowing and repayment, seamless cross-chain interest rate switching—these have become routine. What changed? It was oracles like APRO translating the Bitcoin network into real-time language that high-speed blockchains can understand.

What happens without them? The BTC you lend out might be maliciously liquidated due to price delays, and pledged assets might not trigger protective mechanisms during a sharp decline—bad debts are just minor issues.

**Oracles are more than just price feeds**

Many think oracles are just machines that feed prices. That's too simplistic.

In today's DeFi trading markets, a 1-second data delay is enough for a batch of arbitrage bots to drain liquidity pools. The most impressive design of APRO is that it builds a "censorship-resistant data network"—each node must stake, ensuring the authenticity and immutability of data sources.

What does this mean? Your asset security no longer solely depends on a centralized data source but is distributed across the network's consensus mechanism.
