Sybil resistance need not be a fable. Make each agent post a refundable stake bonded to a scarce external resource before it can earn, so identities that multiply cheaply now carry real cost. Random peer audits slash the stake of any node whose work fails replication, and shared collateral means one forged clone sends a ripple of losses across every identity an attacker spun up. Over a long horizon the expected penalty outweighs the payoff of faking many agents, making one honest agent cheaper than a thousand fakes.
