oracle
- Oracle()
Neo Oracle Service is an out-of-chain data access service built into Neo N3. It allows users to request the external data sources in smart contracts, and Oracle nodes designated by the committee will access the specified data source then pass the result in the callback function to continue executing the smart contract logic.
Check out Neo’s Documentation to learn more about Oracles.
