#apro $AT A One-Sentence Understanding
If we view blockchain (like Ethereum) as a closed but absolutely trustworthy computer, then a decentralized oracle is its "eyes and ears" that securely connects external real-world data.
Why do we need it? The Core Issue
The core advantage of smart contracts is "trustlessness"—as long as the code is written, it can be executed automatically without intermediaries. But it has a fatal flaw:
The blockchain itself is a closed system and cannot actively retrieve any data from off-chain (the real world).
Apro (or any decentralized oracle) essentially builds a "data bridge" that is as secure and reliable as the blockchain itself. It inputs external world data into the closed blockchain environment in a trusted, tamper-proof manner through a decentralized network structure, economic incentive model, and consensus mechanism, thus unleashing the infinite potential of smart contracts to truly connect with the real world.
It is a crucial part of blockchain infrastructure; without it, the vast majority of valuable DeFi and applications would not be able to operate. @APRO Oracle #apro
