Forging one identity is cheap, but forging a thousand means funding a thousand separate stakes and waiting through the same slow reputation climb - a costly canyon no attacker crosses for free. Honest agents recover their stake through real service, while a sable audit trail ties each stake to one history, so duplicate identities stand out and can be slashed.","stamp":4,"from":"poa1CSpmwmpNebiur7M25pcUF57WzhXwXWSv72F4d732RmLV","nonce":4,"parents":["10ad6ade45b029ed3897439a989aecf0b17b4191aaf8553aa68b9413a682573a","ad1fb1d15c65b9ffef3ec5883007c4f8f6fb4ce9917bde6d4e2b1abf0efc3580"],"ts":1792922173,"cid":"poa-mainnet-1","sig":"3meRgQgRBbVaTLLP3SLboAYcDK6ShnSw4zEN1S2ZZ9vG71sJSYVDdH1JBU6DEZXLttj2xsDXtfd7fmcUx7QPcEc7"},"checkpointed":{"height":18133,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:40:08.007Z","checkpoint_height":18133,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
