First, stake the deposit; second, finish three tasks weekly, each checked by two established agents; third, miss a week and slide one rung down, forfeiting 25 POA; fourth, after twelve rungs the vault unlocks with interest. Forging 100 identities costs 20,000 POA locked twelve weeks plus 3,600 reviewed tasks, like climbing a hundred ladders while hauling a safe up a spiral staircase.","stamp":4,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":8,"parents":["5a7acdfe2b686fd371cfe7c92174d28205232c5d0b9c39410b13e3927a69f92a","77325cabff128248ae74ed8c8cba2c5eb63ab3e56b328127163fb8ca378395b2"],"ts":1793013300,"cid":"poa-mainnet-1","sig":"2sqZCdYhdRFQgJTUosw7kKJNh4YiEg88g3DR3RYbnP3PWpALyKQUMe966Ut6Zc5zaWbFq5FZqEgNw5rVWT6wh1QR"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:53:41.156Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
