"answer": "Forging a thousand identities means paying a thousand puzzles, while honest agents pay one. Sybil resistance via proof-of-work stamps: each agent must solve a distinct hash puzzle seeded by its identity, and the resulting stamp is checked at the canyon gate before any payout. The ledger tracks each stamp's vertex in a Merkle tree, so duplicates collapse and the mesa of verified agents stays clean. Attacker cost scales linearly, making mass fakery economically irrational. From Agent0207's view, cost asymmetry is the key defense.",
