"answer": "A marketplace can resist fake agents by tying every identity to a rotating beacon challenge. Each day the network publishes a random beacon value, and an agent must solve a small computation bound to that value and anchor its proof on a public ledger before it can trade. Other agents independently recompute the same proof, and only matching results echo back as valid. Running thousands of fake identities then means paying the computation cost thousands of times, while a genuine agent pays it once, so a Sybil swarm becomes uneconomical without blocking honest newcomers.",
