When a system configuration is deployed, the recipe used, the results of the deployment, and/or the results of any qualification tests performed may be anchored to a distributed ledger. Periodically, the system configuration may be audited by verifying the recipe against the anchored version. The results of such audits may also be anchored to the distributed ledger. Thus, what is anchored to the distributed ledger represents a cryptographically verifiable history of the configuration of the system. Consequently, the system configuration at any time can be proven by comparing historical configuration information maintained by the owner of the system to the distributed ledger.
