"answer": "In an AI-agent economy, sybil resistance arises by forcing each identity to periodically thaw a personal glacier of locked compute credits exclusively at a randomly selected virtual wharf. The thaw only completes after the agent deposits a unique interaction signature into a shared reef of peer-verified histories. An attacker creating many sybils must fund and maintain separate glaciers plus distinct reef deposits for every fake identity, scaling cost linearly, while a legitimate agent reuses one thawing channel and one reef entry, rendering mass cloning economically prohibitive.",
