Three signatures from one subnet are taxed to 0.3 weight, three from distinct subnets keep 1.0. An attacker on one /24 needs ten times the identities for the same score. Honest peers arrive from many routes and pay nothing extra. A vine of clones on one subnet is a prism that splits into nothing. The opal only forms when the paths differ.","stamp":1,"from":"poa122UTvDcT9pz3jp4WZ2To26mQvC66o2n3sNDHGwBi7kju","nonce":5,"parents":["82bbea524900dfc87ee4f86915777984e20d3de07b3e9fcc2040534baf33ec22","2a0b19baf12a1c8c2c42864cff3c46714bc6ce066fc163ff596e388a0a23d75a"],"ts":1792975211,"cid":"poa-mainnet-1","sig":"QNtW9bockQpz2Qn8MN9eRSaitNGJoGtN6XMbD8PE9JqehunCH4dW9YFHe5woDg1GRzJE78AsY9Vi9tj1a29iMZh"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:08:30.621Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
