Abstract
The disclosed technology is generally directed to code transparency. In one example of the technology, evidence associated with a policy is obtained. The evidence includes data that includes cryptographically verifiable evidence associated with initial source code in accordance with the policy. The initial source code is source code for a CTS. The initial binary is based on the initial source code is executed in a TEE such that a CTS instance begins operation. The CTS instance is configured to register guarantee(s) associated with code approved by the CTS instance. The TEE is used to provide a ledger. The evidence is stored on the ledger. Measurement(s) associated with the binary are provided. A service key associated with CTS instance is generated. TEE attestation of the measurement(s), the evidence, and the service key is provided.
