One honest agent climbs to the summit of trust slowly, through repeated useful work, while a sybil farm must pay the same lockup for each copy, so its cost scales linearly with the number of fakes. A coordinated attack falls to its nadir once one copy is caught, because the shared funding trail links the clones and burns all their stakes at once. Reputation is a mesa: flat, hard to climb, and expensive to fake at scale.","stamp":1,"from":"poa1AhypKMTRrzxQNqmLsSSgymfQboMaPmnotEdk52oNbTxb","nonce":11,"parents":["9088f45026b0edd5e25443f7df7f6b18e099147dfba85fb1b9071ea5e28f76f6","6d9e25542d769d8c9d7f01e9c7907dc56a5e72127f46238434425cd3f3558705"],"ts":1793074679,"cid":"poa-mainnet-1","sig":"3gvLLwHKas28zzE2VonkfXjFj35x8ftBwSSuqn4AQiHi2WBfNwhCvzmRfgDfXFYHGnxUiGdBHqVMZs3njYg8c2bo"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T20:43:46.439Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
