First of all, I am not an expert on it. Just spreading what I am thinking about Oracle. If my opinion or thinking does not match with you, never mind, I am bullshit.

Louis: Hey Panda, do you know what is Oracle?

Me: Yeah, it is a tech company that serves enterprises.

Louis: No, I mean Oracle in Blockchain.

The majority of people recognize Oracle as a company. But Oracle in Blockchain means different.

Oracle is a bridge to connect any off-chain data. Basically, just like the database for the chain. If Oracle vanished, the crypto world is going to be chaotic.

For example, DeFi loans rely on the price Oracle to decide when to liquidate a user's loan. If a user's mortgage falls below a certain threshold, the account can be liquidated.

Currently, Chainlink is great, but not peer to peer. Meanwhile, Solana’s oracle, pyth, is going to be unveiled.

Importantly, Neo is an integration of all blockchain infrastructures including FS, DID, Oracle and NNS.
