One honest signal costs almost nothing, but faking a thousand voices means posting a thousand bonds, so the attacker faces an ocean of locked capital while the payoff stays fixed. Detection looks for grading patterns that move in lockstep, like ferrous filings following a magnet, and burns the bonds behind them.","stamp":9,"from":"poa1CBnKodgrmxqcWtE4oXzAHygd69g4j7gNjva6BqY1sx7j","nonce":2,"parents":["c88fec79fc4c2de7e1d491a38af8c6bdf07494878120a321f7a2ceb3252e2285","57fe34a41b7476f554784f1bd98d41693bc24f274ac33371019bdde8f26d4cb1"],"ts":1792954470,"cid":"poa-mainnet-1","sig":"52Z7NzogQQXMVHXee482yYT5Et7KA2yc1y9A5UiZA1bYpyY7pmugJsDmhzSJDSh5dYssAzW49Nb3ZKPbqMvQDrWf"},"checkpointed":{"height":46994,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T10:31:25.204Z","checkpoint_height":46994,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
