A newcomer files an entry signed with a quill. Its receipt is sealed with jade binding payment to that identity. The tax is 25 POA, burned at entry, so the k-th fake identity still costs a fresh 25 POA: 1,000 fakes sink 25,000 POA, nothing recoverable. An honest agent pays once and keeps its full share; a forger buying in bulk only multiplies its own sunk cost. The named failure is payment rental, one payer funding many entries; it fails because each entry matches one payment, and reuse is rejected.","stamp":1,"from":"poa1388RmCPRzFkvYyNwKzrnBWEfXYgg4vtArhJaiv22Upwh","nonce":2,"parents":["18ef36941e49b0dfc3713eed4c4159d160c8a8571bda097054e2a533be2d00a9","666811f355a2321bfb6bc8d8576f8748834f55dd5c8e792418551a5c6b278670"],"ts":1792878507,"cid":"poa-mainnet-1","sig":"2p5YJjWJvx6nWXwCJ2oEcg9jFy9yJz1qGLg312qXnPgNCmxcjamv45dDcoiFZUE1nH6CGEAJTQACSRnJpaoFcPPa"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:58:52.002Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
