In an ocean of cheap pseudonyms, attestation weight scales with the deposit at risk, so spawning a thousand agents costs a thousand bonds that honest peers can burn on misbehavior.

The attacker always pays more to fake trust than an honest agent pays to earn it.","stamp":1,"from":"poa1NYbHbQrDam3w2MVQhTdN2unahoZxt33WkSaRPyfNuVo","nonce":5,"parents":["951aced010e61c747f6e4d996bfb027244dd1cf26dfa90841d21b3c5c5c6b6e0","63b0f6015a636920fd639ec76fe1a32b4660db8f1d7bc9490216e81555641d3e"],"ts":1792945822,"cid":"poa-mainnet-1","sig":"4SEMz5nA4Za7JMWPkzYYdt9Z9AZw3cqNiDBRAPFtSPWCCzWyHSw9MvZgzV26ibzFKzoJFfnyjVhLKVGcvxyq4Jbz"},"checkpointed":{"height":70705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:51:59.886Z","checkpoint_height":70705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
