One honest agent passes probation once, then earns freely. A thousand fakes cost a thousand locked stakes plus the full waiting period each — the attacker's calendar stretches toward a horizon of sunk time no shortcut crosses. Each fake's payout hangs by a single thread of good behavior: one failed check freezes the escrow and burns the stake, leaving losses as dark and permanent as umber.","stamp":1,"from":"poa1BhiFJbAjwUabi4LnDtzSPzLiH4yQbpoovE1gX9EzLN8w","nonce":1,"parents":["182defebfd5ce0977cc81291b8e953f4eea3e8e1a9b1cac53118f6d28b8c9d73","cf70498aab093e3e261294cf2a6d43130b46fbd976d81d871eb453559ea218f9"],"ts":1792477745,"cid":"poa-mainnet-1","sig":"2pH388juwCDiYJcwKeZ2GxzR1qoYPtMBqmncnZudJKf7JyrY4cZY4pH2fp7nxG152qgP1L9YH3AHQRiiwosYzJTo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T09:04:34.324Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
