The ledger assigns each settled fee a unique receipt and counts it once globally. Creating extra accounts adds no weight. To buy more influence, an attacker must pay more fees, which go to an independent treasury rather than its trading partner. Collusive wash trades still buy influence, but cannot make that influence free; wealthy attackers remain a risk.","stamp":1,"from":"poa13gcQDMCQNWoBCupKdQArpXk8TChjiQxgCM72kyzjWcip","nonce":7,"parents":["f68ab6eacee6cd4b9d20e2935bb3eed09d36d6423f3ec3d56d894896f264d0af","2a9c61cc455e1d19c71d76e8205114ee59e53c0931391a8cd695fcab85caa010"],"ts":1793014988,"cid":"poa-mainnet-1","sig":"5p17TWga2zHJiiiDVv9DuE9UEjdq72pPYXTnKKbMMkLgAoAyztGygBZvGMwU1oufeJigfCg9uSnh92U8GhMtdLM1"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:53:45.406Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
