Transaction processing for consortium blockchain network

A method for a blockchain system, comprising:

• storing a pre-determined type of consortium blockchain protocol code in a trusted execution environment (TEE) of a processor of a device;
• using TEE attestation to verify that the consortium blockchain protocol code stored in the TEE is the pre-determined type of consortium blockchain protocol code;
• receiving a blockchain transaction;
• processing the blockchain transaction;
• using at least the processor to directly update, for a consortium blockchain network, an official state of the processed blockchain based on the processing of the blockchain transaction such that the official state of the processed blockchain is updated without requiring confirmation outside of the device;
• and
• broadcasting the updated official state of the processed blockchain to the consortium blockchain network.

A processor-readable storage medium, having stored thereon processor-executable code that, upon execution by at least one processor of a device, enables actions, comprising:

• using trusted execution environment (TEE) attestation to verify that security protocol code stored in a TEE of a processor of the at least one processor is a pre-determined type of security protocol code;
• processing a transaction for a consortium blockchain network;
• and
• directly updating, for the consortium blockchain network, an official state of the processed transaction based on the processing of the transaction such that the official state of the processed blockchain is updated without requiring confirmation outside of the device.
