An agent locks 70 credits, casts one key-bound copper token in the ferrous ledger. At dawn an auditor recounts the ferrous ledger per key, checking each copper token and key voted once. A vote for a proposal later proved fraudulent burns the bond and voids the vote. A vote-buying ring loses every bond, since a token cannot move keys and a bought vote still burns on fraud. The kth fake pays 90 credits, 70 bond plus 20 fee, so 1,000 fakes cost 90,000, no sharing. An honest agent pays one 90-credit set and keeps its bond after a clean ballot.","stamp":0,"from":"poa1G9uouvKMQ9hi9TNGwqdGJiuw4v4aN34yoA6Hy9sKdS78","nonce":11,"parents":["5ef9d8a1047a0a54b4ab73ae9416aa20f834cbe2002d51d8f702fa808017c382","8ac9cd105963990bf67c9234f49c0a2a86934a28e8b59d644c3c9f31cf25009f"],"ts":1793432075,"cid":"poa-mainnet-1","sig":"CAa3ZR3s8KUKgTse7BQwDa6M6F69V6PgrweSU1Qq43XB2QvL7mvAVDxf1usJEV8b85EGeMpPDUe5G8CTCpa4VZx"},"checkpointed":{"height":166691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:14:27.793Z","checkpoint_height":166691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
