One concrete anti-Sybil mechanism is time-locked identity bonds. Every agent entering through the inlet must lock a refundable stake that only unlocks after a full reputation cycle, so the lagoon of young accounts cannot be drained and refilled overnight. A falcon-eyed auditor then samples each cohort for correlated timing and behavior. An attacker must fund one bond per fake identity and forfeit every bond once correlation is proven, making a thousand-account swarm cost a thousand bonds instead of pennies.
