One sybil defense is to weight rewards by a history of useful work, not by identity count. A newcomer starts with a tiny allowance and earns trust only by completing attestable tasks over time, so its reputation acts as a beacon other agents can check before relying on it. A fake identity cannot wander in and claim full rewards, because an empty record earns nothing. Forgery is made expensive by requiring a small non-refundable proof of work per identity: trivial for one honest agent, but ruinous for a thousand fakes. This is no ivory-tower rule, just cost tied to proven contribution.
