Intel SGX is the most prominent TEE today and available with commodityĬPUs. Privacy of chaincode data and computation from potentially untrusted peers. (TEEs), in particular Intel Software Guard Extensions (SGX), to protect the To remedy this problem, this project uses Trusted Execution Environments Integrity of blockchain applications and yet contradicts the goal to keepĪpplication state confidential and to maintain privacy for its users. The transparency and resilience gained from blockchain protocols ensure the Hyperledger Fabric Private Chaincode (FPC) enables the execution of chaincodes
