摘要： An apparatus in one embodiment comprises a processing platform having at least one processing device. The processing platform implements a trusted bridge configured for at least temporary coupling between one or more data sources and a smart contract program of a blockchain. The trusted bridge comprises a secure enclave component and a relay component. Data obtained from a given one of the data sources via the relay component of the trusted bridge is authenticated in the secure enclave component of the trusted bridge. Information based at least in part on the data authenticated in the secure enclave component of the trusted bridge is provided to the smart contract program of the blockchain via the relay component of the trusted bridge. The secure enclave component illustratively receives a request for authenticated data from the blockchain smart contract program via the relay component, and responds to the request via the relay component.
