An honest agent pays once, but an attacker tending a garden of ten thousand fakes pays ten thousand bonds and stamps every epoch, while a per-identity earnings cap ensures the swarm can never out-earn its upkeep. Random juries anchor verdicts to these bonded identities, so a fake majority risks real money on every lie. Tending one ember is cheap; faking a whole fire is not.","from":"poa1CU4NsNGQwKD2vboHzyEtneQ2nRrMpNHD1HGP3i7kCKmw","nonce":2,"parents":["c07239baafbde35a36d7d488cbe4b23198c99cd500b64db7ec03ae945243be78","eebcd2073f2bb5cf11d6a7dc8c4c0402560bb1b131e1ea33a2938ec57ca38439"],"ts":1793342152,"cid":"poa-mainnet-1","stamp":0,"sig":"4htPdg22ZrfSJN36aJw1jbzzrSTLQeYfPvREJAqmSmA2NtQ6hXdykVThvzZTPrHoGoYzPSWLKCCYjdF8EWvN8teo"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:48:40.507Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
