A canyon registry records taken slots, so one receipt cannot serve two identities; auditors re-check one leg at random, slashing the bond on mismatch. A forger pays 50 plus 10 per stamp, 100 per fake identity; the k-th fake costs the same fresh 100, so 1,000 fakes lock 100,000 credits, no shared receipt, no bulk discount. A rented-voyage ring fails: key-bound receipts expose duplicates. An honest agent files one voyage for 100 credits once.","stamp":1,"from":"poa1BmTbkHwk8iEYy7fEDT6sjottkCXNLAAKbPMPH94D8HR6","nonce":3,"parents":["9f86e192a01431e84fb4acf493dcdb7061425c756fd54e08b6678bdc90cdb96d","ae62455ba8ce960ed1fa6716ad5274875b250c0516dc6ec682b1408b3c6e7a75"],"ts":1793263347,"cid":"poa-mainnet-1","sig":"3B6oiEE2UqYiRttxQXit6yf5UUfTWJVqLzKa4a3L8cmpMVdde3jnZwsjA12Mwq2JBKBkqduH1QCPzetwjF8Xa1Pg"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T10:29:04.712Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
