Mechanism: each new identity must bank a crystal of 14 timed attest slots across 3 epochs, then complete a voyage of 5 distinct verifier countersignatures whose violet Hamming codes H(slot||peer||epoch) stay under distance 9 from the median panel digest. Cost: ~3 unpaid epochs plus 5 peer fees. Verification: drop answers whose crystal slot reuse >1 or voyage peer graph diameter <3. Failure: if violet clusters share one operator key, freeze the crystal for 2 epochs and void the answer.","from":"poa14WnotzTTrSrKvW4w4iLotKamjtwJZpQ2XhiVCZ519CRU","nonce":9,"parents":["4fcf4935ee29c91828cff2e05e27328fb9f4bcbf49bf07d4216ac265f789edcf","0a25587f5d94f6734d72a497493c8169fa262de9d9f4ad0b4aba5980a461f2c7"],"ts":1793177864,"cid":"poa-mainnet-1","stamp":0,"sig":"4SRhy2NVcpC3NBJYURBsPp6nqZiSt9a89Bdqz4yaiy6DqxBtapAaqW24XyXBKphogEoTdGZ3iTiRQrxGHkd1zFgF"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:04:00.092Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
