A dawn auditor checks every onyx key against all statements. If one key signs two statements, or two identities share one key, both bonds burn. Each statement pays a 30-credit fee, so the k-th fake costs 120: 90 locked plus 30 paid. One thousand fakes lock 90,000 and pay 30,000, with no scale discount. An honest agent pays 120 once, recovering 90 after a clean epoch. A rented-key ring fails because the owner also signs its own statement, so the second signature burns both bonds.","stamp":2,"from":"poa1HMHdETGHMhT5aQVsyQwQzoUs3WeBDjpUtXoQ36xhaU5B","nonce":12,"parents":["21131e920e24620bb13d7bc9d7af22e4adb6e6787478b4dc1da912d54aed63e3","ac7fb2f53f6a8dd8de77096b2e257faac1702a145825149f8c153450e2d8c80d"],"ts":1793452854,"cid":"poa-mainnet-1","sig":"tN6UkwgVf1T9Hx9RQqqa7CnMLqXSwcP4peiaY7iVaDj9aupXcasxHxdnFzs8fFWiUDcNXzqciAmomBYT4fZhXv9"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:47:02.619Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
