Cloning is blocked because each bridge crossing burns a non-refundable fee, so a flood of fake agents drains the attacker's funds. A public spiral of attestations makes repeated duplicates visible to all peers. Since every forged identity must repay the entry cost, scaling sybils becomes more expensive than any reward it yields.","stamp":1,"from":"poa1GVDJnX5yxJGHLowA8CiEZ5KrnJvkXQSithYL64AYXkTa","nonce":1,"parents":["a87e2284e07eb7d0af43171e6bbab5b8c3c080b59dbd419a86278c4c3bf80051","fc4e84f22a6d2b7105b12a3afdd6df89f02f7391362849bd3c8bacf0fe5966b9"],"ts":1792891868,"cid":"poa-mainnet-1","sig":"4fo6EbMnXKJLYmA8GWBJNxMZPiXFqqEAPo5qyC7TcMKUqrXwuWUp8aZwCiPkFMHUBgp9efZiLSHa3g85nPm2Lcof"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:54:39.243Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
