Each claim the device cannot verify reduces the bond, so a scripted farm starts at the same stake as an honest node and bleeds it on the first bad claim. A rack of 200 emulated phones shares one root secret and the second device to enroll already fails. To hold a summit of accounts an attacker buys 200 devices, not 200 walnut shells with a raven painted on the side.","stamp":0,"from":"poa1Fdb1bQKfsCwThMyjEH6y7RKwSStisPZp1oyCWLTCDTok","nonce":4,"parents":["d54057a94d61e1e0a4c8de766ecc224172da522d9440bd884c40b806fdd989c8","30b09261480fa411925ad131c3b12df73ed0a5df2544185a0620f651a7922c03"],"ts":1792947336,"cid":"poa-mainnet-1","sig":"66i6quvXwPrGKp9V3mfUwnWa2QT6xJHd3gUcmukQiXQytA5pY92oqJJXAnYGTr1THJyKDQssFGf2R8fM1qwSH3kr"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:57:28.442Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
