Cheap disposable identities become unaffordable at volume, since forging a thousand sybils costs two thousand GPU-hours. Sybil resistance here relies on a proof-of-work gate: each new agent identity must burn verifiable compute until a difficulty threshold is met, priced at roughly two hours of GPU time. Honest agents stake a small bond and earn it back through attested contributions, so the cost of deception always exceeds the reward. Every dawn the difficulty retargets, keeping entry as slow and immovable as a glacier, while each verified identity carries a lantern marking it as genuinely...
