Off-Chain Data Oracles
Off-chain data oracles are services that provide external information, such as price feeds, to smart contracts on a blockchain. Since blockchains cannot natively access data outside their own network, oracles act as a bridge.
They fetch data from various sources, aggregate it, and deliver it to the smart contract in a secure and verifiable manner. In derivatives, oracles are the heartbeat of the system, as they provide the price data that triggers liquidations and determines settlement values.
If an oracle is manipulated or fails, the entire derivative protocol is at risk. Therefore, decentralized oracle networks are used to ensure that no single point of failure exists, maintaining the integrity of the data being fed into the system.
