CONSORTIUM BLOCKCHAIN NETWORK WITH VERIFIED BLOCKCHAIN AND CONSENSUS PROTOCOLS

摘要

The disclosed technology is generally directed to blockchain and other authentication technology. In one example of the technology, a pre-determined type of blockchain or other authentication protocol code and a pre-determined type of consensus code are stored in a trusted execution environment (TEE) of a processor. In some examples, TEE attestation is used to verify that the blockchain or other authentication protocol code stored in the TEE is the pre-determined type of blockchain or other authentication protocol code, and to verify that the consensus code stored in the TEE is the pre-determined type of consensus code. A request to alter the pre-determined type of blockchain or other authentication protocol code may be received. A determination may be made as to whether to change the pre-determined type of blockchain or other authentication protocol code based on the pre-determined consensus code.
