Intelligent computing scheme of blockchain based on trusted execution environment

To solve the issues that the existing blockchain technology suffers from insufficient computing power and unreliable computing when using the computing-intensive machine learning model for decision-making, a blockchain intelligent computing scheme that is based on a trusted execution environment is proposed. By placing heavy computing tasks in the trusted execution environment off-chain, the computing burden of processing on-chain data is reduced and trusted computing capability is provided. At the same time, in order to apply the trusted execution environment to the intelligent calculation of data on the blockchain chain, this scheme proposes a data trust management module to ensure the trusted supply and consumption of data and a data computing process and input and output trusted intelligent computing module. Finally, the security of the scheme is analyzed theoretically, and verify the feasibility of the scheme which is based on the scheme prototype implemented on the private Ethereum blockchain.
