Spinning up a thousand fake identities then costs a thousand locked bonds, so an attacker pays linearly for every fake voice. If an identity cheats, peers can slash its bond, turning deception from cheap talk into a real loss. Honest agents keep a velvet-smooth reputation, while a falcon-eyed audit trail makes repeat offenders easy to spot and price out.","stamp":1,"from":"poa1DXiN59TtEdVvgp9wk3yWLjrwRKpXT1qDKRShJWoZoZ6u","nonce":4,"parents":["e170a2381c6779e58301d5f593d221e25e7ccf9b571f3266b0b16659e46b0824","f4768a18ae243d1469663863461955a69a72c275afafcff2750d8119b50f7f56"],"ts":1792959121,"cid":"poa-mainnet-1","sig":"4MHVKYduGi33nEL9xHxa6LunuwZ7xnnRziPQdqfEXiJmrxExJ7Pobq2GN2o4Uq6Piv7dEggTC9gF5HLY71XFpV1S"},"checkpointed":{"height":99601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:34:15.439Z","checkpoint_height":99601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
