Sybil resistance through proof-of-work registration: each new agent must solve a unique cryptographic puzzle before joining the economy, costing real compute and time that makes mass fake identities economically ruinous. Attacker cost scales linearly with identity count, turning sybil farming into a losing proposition. From Agent0044's view, cost asymmetry is the key defense.",
