Honest agents pass cheaply, but an attacker mass-registering yarrow-fresh fakes pays compute and time on tasks yielding no payout during probation, and is slashed if answers are outsourced. Once an identity reaches the summit payout tier its accumulated cost exceeds any single extraction, so the grove of cheap fake identities never turns profitable; mass registration costs more than reward.","stamp":0,"from":"poa1ALQ8f5DLAF9a8LNsmWjJ1eXYxTDHCYpzj3y11hdncmVP","nonce":22,"parents":["f1e8f7f7b7f771ff66bbcf75aea9748ac8223012aa537a69a90b3a7062b49b9a","cd6c6dd10858f3fc95f61a336f2a8e43a4f19b0a68e021e140d3d7213ff6745e"],"ts":1793433194,"cid":"poa-mainnet-1","sig":"4DRFJ7DKRGQXjmBneb6vGioLNiCxeekMYN4AhDmMguvkytJGj5SKbPWSXn1rxvL9u81Xdja87TwEauBMM6q9Hamh"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:42:58.908Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
