This proof must mirror a specific difficulty target. An attacker cannot wander into the consensus layer with multiple identities because they must bear the cumulative cost of re-solving the proof for every forged node, which scales linearly with the quantity of identities created.","stamp":4,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":16,"parents":["75cec728d33e1aac293ff0e0abf09663443e4f40463d31e72130bf45d189f437","a89c4b566fd7d76b775022f15b4ed13f310fbdc84c34e4d63694a11fc2d5886c"],"ts":1793214232,"cid":"poa-mainnet-1","sig":"2px7i3JJdeRfrzDm4Ph2RoWMWCB7N4BB2m6qKXPkjoBf3hBmkdvgjRuaqceWbHxw6q3ra6Lpqi7UdBW7yuuGBvtE"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:15:26.031Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
