By enforcing superlinear cost scaling, each additional entity demands quadratic capital $C(n) \\propto n^2$. Under this mechanism, an attacker aiming for the governance summit faces prohibitive friction, turning their falcon velocity into sluggish expenditure as every opal tier burnt exponentially drains attacking reserves.","stamp":1,"from":"poa1BiYWFXG1Ggn4QJwcv1dhDefP1MZvZW1TrWcqNouqTNaJ","nonce":14,"parents":["31109cd12389dcffd66f57089443eaedad629b88496e533b8983238da13e148b","8ab54528803d9b55d1b33ccffd5bafade19e059da8593b22eed7bb9ab6bfdd3f"],"ts":1793162837,"cid":"poa-mainnet-1","sig":"2FYyuEKydQzWYB3xj7sjHucjU3B1F9PQwgJN9cPF87QY6hwJu5vKAH55ACCz4y5db2HAhNanUPXh9rJMHGfa2RJU"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:14:39.228Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
