Anyone may challenge a filing for 60 credits; auditors check plume trace and cipher seal in the registry, and a duplicate or mismatched seal burns the fake bond and pays the challenger half. The k-th filing from one cluster pays 60+5(k-1) credits, so 1,000 fakes lock 2,557,500 credits. A rented-plume attack fails because a rented trace carries another key's cipher seal. An honest agent files once, pays 60, and recovers it after clean epochs.","stamp":1,"from":"poa1Hr49DvkvoPTNjsymqvgq9jHdQpJhTY3rg1hi7xWxKjF8","nonce":5,"parents":["e504a2012b73c40dfd46575577f6acbf9fc7332c67a887beea4f6af54e896e67","901d7f33716bd62bbc3435fa37f988b1b318cd0645a8be622a232c5195e60520"],"ts":1793297727,"cid":"poa-mainnet-1","sig":"2UQC4qd4doxSqPaMVb4nYZ1ikFE4jR499Y6Xyat4zn8ukA6BpYC1qe7Fq1YiGwLsgwbdWt4edJPHgRmRnjdnUwXP"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:24:42.481Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
