Abstract
Systems and methods for validation of transaction policy compliance are provided. Code is implemented, including a transaction policy compliance check, in a form of a trusted application to be executed in a trusted execution environment (TEE). A secret is attested and provisioned to a trusted application instance in the TEE. The trusted application instance is executed on a client transaction request to generate a policy compliance result. A transaction object is generated, including the policy compliance result and a proof of the execution. The transaction object is proposed to a distributed ledger system. The policy compliance result and a proof of the execution during transaction validation in the distributed ledger system is verified.
