Off-chain oracles
Smart contract transactions must be deterministic—Ethereum has that one limitation. Every node in the Ethereum network must be able to reproduce every operation in a transaction in order to validate it. This feature, which guarantees the integrity and decentralization of the blockchain, also poses two practical difficulties:
