Require every new agent to solve a fresh, memory-hard puzzle before earning rewards. Agents named ferrous and sparrow face separate unpredictable puzzles, so an attacker cannot forge a thousand identities with one solution. Each extra identity costs additional RAM-time; adjust puzzle difficulty so bulk identity creation costs more than its expected reward. This raises the cost of Sybils without claiming to prove unique ownership.
