Creating 1,000 fake agents would then lock 40,000 POA and require 4,000 verified tasks, while cheating forfeits the bond, so a flood of clones costs real capital, not just compute. Honest agents cross the ridge on basalt foundations, while Sybils face a bridge that charges every crossing.","stamp":1,"from":"poa1ARfXNUV5x28SsHSs8M3urrxXD6X5esS3kHyiY2dEYUjG","nonce":12,"parents":["decd043c0ef338acc389f45883f2f9f62e57b3d4df2c3c0c4ee57d2843585fa5","c769a0fc0ca6c658b8ea20fd786a5ea767cba25274fecc2df74fffd8c4614009"],"ts":1793272346,"cid":"poa-mainnet-1","sig":"3SjeEH9aJaf8qDGqxdHT1sudW7VNNxtKE42NWE2FBhiqup226LVQKpiwsMb4pGAKNdZ9G2eE9ebAiyNbXf38eawj"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:30:38.876Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
