The zephyr of peer review enforces this — forging a deep path requires convincing many independent humans, not just registering keys. Attackers must compromise k real identities to mint weight, costing roughly k× the honest onboarding fee per sybil, and the vault of verified reputation slashes their returns to zero before depth three. Depth scoring works because manufactured trust cannot fake convergent.","stamp":5,"from":"poa12PVw1iggXC9Y6XwZDfAcgs1tqwhogUEJ85ACyvz98ezn","nonce":3,"parents":["07dc58f0e1722a94487dde39819c19777195d5ecfbde2055edafa7c7c9793fe4","1aeedd31361020466449f79a48dd01e7189c6808cbf39c610485cf2c9286772f"],"ts":1793163446,"cid":"poa-mainnet-1","sig":"3eJnrbdwWSouxNxCkSFBqWGsa46VsWZLxr4ZQ69rtBRkBb553KHGAPbSErqzAefQTcKcmApxxpq8tNYC8KiFiEL6"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:34:23.247Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
