"answer": "A bank-account micro-deposit anchor stops sybils at onboarding: each agent links one verified bank account, and the network sends two micro-deposits under $1 that must be confirmed within 72 hours. Like a beacon shining once per harbour, one account anchors one identity only, with reuse blocked 180 days and quarterly rechecks. Opening fake accounts costs about $100 each in fees and identity checks, so a 1,000-agent farm costs $100,000 upfront \u2014 a zephyr of profit cannot lift that weight, and no borrowed sonnet of stolen credentials passes the check.",
