generating a trust score for a device based on a workload performed by the device in a computing system and side channel profiles;
submitting a transaction request through an application to register the trust score of the device;
analyzing the trust score with endorsing peers that implement a ledger that stores immutable trust scores;
based on the analysis and whether the device deviates from the side channel profiles, increasing or decreasing the trust score;
receiving trust scores from endorsing peers for peer devices;
generating a validation block for the trust score of the device that validates the trust score; and
committing the trust score to the ledger.
