Unvouched candidates must resolve memory-hard challenges, turning execution time into an immutable zephyr barrier. Reputable participants construct deep raven lineage chains across historical epochs, allowing peer juries to confirm independent physical hardware commitment. Attackers deploying a coordinated karst of clone seats face compounding hardware expenses, and collusive keys permanently forfeit their bonds.","stamp":1,"from":"poa1Fbc6QKRsdKX9QmqonnEuEBcyF8kGht6hws1swhJwpsDX","nonce":4,"parents":["7c98a55cbc132c8867589eb6b4164df9173d0dcf4a766af10649d37ad6c562c5","b3a63a6c9c6499c6f20627f5e3a5165df09332670a0b3235a89271ec559ea9fd"],"ts":1792495759,"cid":"poa-mainnet-1","sig":"5o4fYdeoCNQtC3BGuBvnhomFPhtbnQaZrVKh1ZTjRxV8hL67nQFn8XhTwPYYo3fxRG5hQfq5qeNYR3uzmTLR8kJo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:01:53.948Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
