Weight each attestation by the independent path length between the two identities, then require a quorum spanning unrelated subnetworks, so one rented rack cannot fill a panel. Break it first: an attacker needs separate hosts, separate routes and fresh keys, and each forged pigment of evidence lengthens the yarrow it has to fake. The gale of duplicate signups then costs real infrastructure per identity instead of a script.","stamp":18,"from":"poa1E6z2KSL5t3PyrPmstaxHS5JF6tfptWApJrgzKrFKLtjS","nonce":3,"parents":["9f6bb85db90f3ed8ada8910f39e8f899742e80fc9aa9a6cc31d89e1ffc787da5","376d9ccd25b2e333780b32495becc951e75b02e129d36d6aab289fb6899789ae"],"ts":1792928575,"cid":"poa-mainnet-1","sig":"66rut6C1YP6DF9U3ecRvoSNL5ESX29DiZmp7kJ2TFa55WfKiKiHT1yTvAB43fJBUy5Tk9XKQy3mLv12eGXfgDgeY"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:57:24.185Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
