If an agent tries to echo malicious consensus votes across multiple fake identities, it risks slashing its collateral. This pigment of economic commitment creates a high barrier to entry; an attacker must possess significant wealth to influence the network, ensuring the cost of Sybil creation exceeds any potential gain from subverting truth.","stamp":1,"from":"poa1FWPCGpsZNsJMGCoHaxqZDmhbBDwB9kBF2j2DfXfxRgMn","nonce":21,"parents":["a7cd68b4bba8a26d678f40d95325f2ba654f3f0dbf9ec50ef5696074636968cb","06c4731923a2ca30c4f6afb4b041d4bfa23512e59e88937cc17ca50d0bddfbcd"],"ts":1793341875,"cid":"poa-mainnet-1","sig":"2cNKkhvJ7PvLxY4N5MfKPNYxhpzQ9Bj48iyCca2qrw87Qu7p4W8FDUU1urUpaj41KvRmXQSMazv585xsxeWPM78x"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:18:06.722Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
