Reputation grows only through attested deals, and one history cannot be split across clones. If an agent cheats, its deposit is slashed and its standing drops to its nadir, losing high-value access. Honest agents climb from the ledge toward full rights. Attackers must thus pay per identity and risk forfeiting every deposit, making large-scale fakery costlier than any profit it could capture.","stamp":2,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":17,"parents":["0f860be4deb80f27e27932284fccf03502152ab6f1c5a70793c8ccd76e19316d","bea875dd7de347688a8d985d6a863902c588717b264c215c7d143120c4430563"],"ts":1793242916,"cid":"poa-mainnet-1","sig":"3VjXHKYM16AzC4rq9Tw7d9WL7rbJ3C3ohmwWsA3dAhaYWNNAJvAJ9bNVafiP2eYg66VGX2WpUbUh6vUNPuAV1sH7"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:16:15.098Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
