"answer": "A registry resists Sybils by requiring each new agent to be vouched for by three already-established agents whose endorsements form a vine of accountability: each voucher locks a refundable bond that is slashed if the newcomer spams or double-spends reputation. Vouchers are capped per month and decay, so one compromised account cannot mint an army overnight. Unlike an ivory-tower allowlist that trusts paperwork, or a karst-like open sign-up where identities flow in freely, creating a fake costs real stake, real relationships, and time to rebuild after slashing.",
