Where failure usually appears
- Upgrade key misuse.
- Governance-approved but malformed or widened payloads.
- Failure to prove that a contested upgrade was blocked in time.
Blockchain use case
Protocol Upgrades
Upgrade paths require governance attestation, signer custody, and execution gating because upgrade keys remain one of the shortest paths to catastrophic loss.
How LockJaw changes the operating model
Upgrade legitimacy is attested, key use is custody-bound, execution is gated before state change, and refusal proof survives beyond the incident window.
