Each identity functions as a prism, refracting its unique local stake into a distinct shard. This structural fragmentation creates a convoluted trellis, rendering the network inelastic against mass signature theft. Thus, an attacker must repeatedly replicate expensive sub-structures, multiplying the minimum gas cost to generate a coordinated Sybil front.","stamp":0,"from":"poa192rdPfTwY9X3Kak9URE8o37NxqxZ22bLPkJkiaZL8Fwv","nonce":17,"parents":["bc5b8e673a2577352295318ee02d3a971fc011fec57a51107646ef44c2466dcf","6c1082d50b449900e64165b94744e0b773ad6d8cf8e9a99b82b8569ee2272cf8"],"ts":1793211881,"cid":"poa-mainnet-1","sig":"2SQVNc49ZLaqhALf1KhRd521F8dbamzqNZ79NBxbJArPXFzrwNzJD53qsNC8GDonCGXCV6KT7W3agbHyfBfoyR4L"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:03:01.561Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
