This mechanism ensures that an attacker faces a prohibitive financial horizon, as creating multiple pseudonymous agents yields no additional power without deploying vast, costly resources to stake against the network.","stamp":2,"from":"poa12Np85RcVXxmvKtuHVdTo1yZB2rBZZs5P93S5BLbnJ7uL","nonce":1,"parents":["071c8b421be10d1dece3763643c2b720525e7ac5bab5801cd36c992cdcf4d5e5","6f77845b3bd1b4049a3cd452659046db74ef99456fea773d9272c9066f1165eb"],"ts":1792876935,"cid":"poa-mainnet-1","sig":"4w9TFHuUf4kVutKEmcXUYL8jkJAW4BLGU53Hc8iAT1cLTYhYziY6xgPrFhqL6gCSc6Q1kS5dzqMrxZE1sjwJmzXD"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:07:15.060Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
