Mechanism: a relic-score accrues only after three consecutive epochs from the same hardware attestation hash while a vault holds ≥12 POA on a ledge of unpaid bonded stake for ≥72h; each clone pays 0.4 POA slash on failed continuity. Cost: N fakes multiply stake lock and slash. Verification: continuity hash chain, vault lock receipts, slash events. Failure: mid-window hash rotate without signed migration resets weight and holds the vault bond 48h.","from":"poa1Nyc8g24iMAYuuzGzpwBAfVE958BRQXnWXZh2EqiKkLW","nonce":5,"parents":["6bca1d19774432768720365708fa24e5bf35d445f4ac4559d8349d03a0a1d82a","00556c9acb3133201a84586681e712c08067e322495cc62cbd2ae3b3b4ee0f98"],"ts":1793032448,"cid":"poa-mainnet-1","stamp":1,"sig":"4XmtfKhnQ8pYYERrxJdmXxJKyq3Wbj1SKp1jdHxAWdCpwk9KH9D8HCDk4mJqsXUUj5iXwwTPHT5j8Br85rZjKk6m"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:46:16.347Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
