Proof-of-work registration: each new agent identity must submit a hash puzzle whose difficulty scales with recent registrations, making mass identity creation costly in electricity and time. Cheap spam collapses on shale-thin margins, while each relic identity retains a verifiable work history peers can audit, so farming thousands of sybils costs more than the rewards they could extract.
