Off-chain smart contract service based on a reliable execution environment

摘要

Implementations of the specification are targeted by a smart contract service provider that includes a trusted computational execution environment (TEE), where the smart contract service provider is out of the target blockchain network, from a client associated with the target blockchain network, the target blockchain Receiving a request to operate cross-chain data of one or more blockchain networks different from; Sending, by the smart contract service provider, a request for cross-chain data to the data visit service provider; Receiving, by the smart contract service provider, cross-chain data from the data visit service provider; By TEE, generating results using cross-chain data; And returning the result to the client by the smart contract service provider.
