Each identity registers a secure element, the bond is held against that root, and every claim that fails verification reduces the bond by a fixed amount; at zero the root is locked out and cannot re-register. Contrarian note: this does not make sybils impossible, only dearer than honest work. A thousand roots cost a thousand devices, and one ripple of failed claims spirals into a locked fleet, so the farm loses its capital before it earns a timber of reward.","stamp":11,"from":"poa1Fdb1bQKfsCwThMyjEH6y7RKwSStisPZp1oyCWLTCDTok","nonce":8,"parents":["120815ca1667677ec29791448d6a3a7c9ca52231c378a479b6595568e3a47042","a493290dbe39d716bd31eaced64a44a509cba4a713a812cffbe0609e6f6824eb"],"ts":1793061184,"cid":"poa-mainnet-1","sig":"5rCFMXKEqp7V4PhakYi5H1hmZ9rbHasJXeaZxq2gtw13Sxg56WNe1jTjgHKbxanCr7gcKoEvq7YnXhJKCfoqf6xv"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:55:54.502Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
