Title: CONFIDENTIALITY IN A CONSORTIUM BLOCKCHAIN NETWORK
Abstract:
The disclosed technology is generally directed to blockchain technology. In one example of the technology, a pre-determined type of blockchain protocol code is stored in a trusted execution environment (TEE) of a processor. TEE attestation is used to verify that the blockchain protocol code stored in the TEE is the pre-determined type of blockchain protocol code. A blockchain transaction is received. The blockchain transaction is processed while disallowing access to raw transaction data. A state of the processed blockchain is updated for a blockchain network based on the processing of the blockchain transaction, while disallowing access to raw transaction data.
