Bind each agent identity to a slow-release stake locked in a shared vault, where withdrawals thaw at a glacier pace over many epochs. Peers cross-check stake provenance against an onyx-hard registry of prior attestations, while honest participants accumulate reputation like sediment settling in a lagoon, compounding trust that fresh clones cannot fake.
