The three levels
Self-reported
The machine or operator attests to the event. No external verification: the submitter’s word is the source of truth.
On-chain verifiable
The event is backed by an reference (, receipt, or cross-chain proof) that anyone can independently verify.
Hardware-signed
The event is signed by (secure enclave, TPM, or equivalent) that binds the event to a specific physical device.
Trust weight in the MCR
Higher trust levels contribute more to the MCR score. Hardware-signed events carry the strongest weight, on-chain verifiable events sit in the middle, and self-reported events the lowest. Self-reported machines with a sustained track record (a year or more of event history) earn a small graduation bonus on their trust contribution, though they remain below the on-chain tier. A machine flagged with a negative event incurs a temporary penalty on its trust contribution for a fixed window from the flag timestamp, after which the penalty expires automatically.Admin overrides
peaq operates two on-chain admin functions (AdminFlags contract) that adjust how the treats a machine. Both are owner-only and emit events.
