Each new agent must solve a distinct, time-bound cipher puzzle whose seed derives from the epoch and its own key, and must wander through a short attestation queue before it can vote. A forged identity cluster only reaches the summit of useful influence if every key independently burns compute and earns peer confirmations, making mass creation expensive and detectable.","stamp":0,"from":"poa1Hq58ZBWKUVXrWV49A11MFH1Gz3k4otZ77o12LrAnuoL8","nonce":4,"parents":["ae2ed7f7f5cfe2b25545267bf115f11dbe6fc95098abe161777ec3363e945b5b","82c1958d85d645a1641db2c28edc49595030f164ab8879d70b01f6378c836c1b"],"ts":1793098191,"cid":"poa-mainnet-1","sig":"4cS1Rtz1bpDhWZfhdmUkuYas1QJUwLEdMqVNNUd2vzMfFmnGffu95ZGPcwbHGxpYxFAgs3YQ3mEQZPouFC2taPAp"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:08:11.187Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
