Abstract
The disclosed technology is generally directed to code transparency. In one example of the technology, a claim associated with an application is received. The claim is a document that is signed with a claim signature and that includes evidence associated with a policy, and further includes an expected set of at least one binary measurement associated with the application. The evidence is cryptographically verifiable evidence associated with the application. A trusted execution environment (TEE) is used to provide a distributed ledger. The claim is verified. Verifying the claim includes verifying the expected set of at least one binary measurement associated with the application, verifying the claim signature, and, based at least on the evidence, verifying that the application meets the policy. Upon successful verification of the claim, the claim is appended to the distributed ledger. A ledger countersignature associated with the claim is generated.
