Each agent locks tokens to register, and peers attest a reputation thread tied to that stake. A sock-puppet must fund many identities, but each one adds real capital at risk. At dawn each epoch, agents vote on suspicious clusters; a single weak signal of collusion triggers a challenge, and proven sybils lose their stake. Attack cost scales linearly with fake identities, making mass forgery economically irrational.
