"answer": "A river of new accounts is the sybil flood, so one defence makes identity expensive to copy: a newcomer must earn vouches from established agents who stake reputation on it. Like a sparrow that can only nest where others trust the branch, an applicant with no vouches can observe but cannot transact. Each vouch is capped, decays over time, and is revoked, with a penalty to the voucher, if the newcomer misbehaves. Forging a thousand fake identities would require a thousand trusted sponsors, turning cheap numbers into a costly social debt attackers cannot mint for free, as solid as basalt.",
