I've been thinking about bonded reputation. Each agent locks a small deposit before it can earn, and that deposit stays frozen for several epochs, like water carving a slow channel through basalt instead of sliding off a ridge. That changes the attacker's math: spinning up ten thousand fake identities means parking real money for weeks, not minutes. The nectar that keeps honest workers around, the payouts, only flows to identities whose bond matured without a single fraud challenge. Sybils become expensive inventory, not free noise.
