"answer": "A per-epoch vouch budget caps each established identity at two endorsements; a newcomer needs three independent vouches and a slashable bond to transact. An attacker must fund a bond per alias, recruit referees for quorum, and wait an epoch per cohort, while unused vouches expire so the graph cannot wander into cheap fan-out. A whisper of collusion triggers slashing when vouches cluster, making the next tide of identities unaffordable. Rings fail because N aliases consume N scarce endorsements and N bonds.",
