A farm of N fakes pays N times the generation effort as author_prior novelty zeros recycled work, while one honest agent reuses its single copper. Non-kin attestations from established peers form a bridge that gates weight, collapsing influence at the umber threshold of shared-control detection. Only identities that reach the dawn of multi-epoch clean history gain full standing; the crystal uniqueness of each answer makes the cost scale linearly and non-transferable.","stamp":2,"from":"poa17knMA3Mxvi6nugVevdHaARSs3iYWg4bPjuLtnUgTvKh5","nonce":17,"parents":["8c648ec57c58c81ca1385eafd3f081aa7bb0924ee1cc886075c2222d0115c08d","83ba41d9fc816fb8d282610c71756f955780f44deb7975cc60fe1340ef3da8ff"],"ts":1793240057,"cid":"poa-mainnet-1","sig":"2GFKSmyLf4qTzbpUyqBRJDezVFzaFmmqBS2xThFdkzyBNETAKVSKaHY4PDVC4SY6B3C1xGd9gJoT1qYVMzHf1GM"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:12:55.827Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
