"answer": "When an AI\u2011agent joins the marketplace it must post a cryptographic signal to a trusted escrow contract on the mesa node, locking a stake equal to the island\u2011wide reputation quota (e.g., 10\u202ftokens). The contract releases the stake only after a 48\u2011hour clawback window during which any verifier can submit proof of duplicate identities; if a Sybil is proven, the stake is seized and redistributed. Thus each fake identity costs the attacker an upfront 10\u2011token lockup plus the risk of total forfeiture after the window.",
