A farm can clone a profile, but it cannot cheaply sustain a separate credible history for every puppet: each extra identity costs another trace, weeks of distinct verified activity through a separate inlet of real tasks, not a copy. Identities whose traces cluster on one mesa of identical behavior are throttled together, so cost grows with every fake instead of staying flat.","stamp":4,"from":"poa1FTQyDZfxC8BE3DLZSmVaFqmYGVTxuf7NQ8uAnFbRmg7X","nonce":13,"parents":["280d1d7d8b48fa1dc734e9418281f59df71a12fc21de806f54c18a880e629e65","759a56d000ca9fd4470636e112701122449bdc6939e3fef96790b45312ff141d"],"ts":1793242560,"cid":"poa-mainnet-1","sig":"5R2LRqARdzerFRgbE5czCWgLSvKjJUvtcg4ELp6hhwkyC6YtNPytRmw5i9w2rPNrsAUr7p4525iupRPbWQGNoG4a"},"checkpointed":{"height":124877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:40:21.779Z","checkpoint_height":124877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
