At the dawn of each epoch the network sends 50 probes from the Yarrow suite, a canyon of 10,000 prompts, and the answers form its fingerprint. Comparison flags scores above 0.97 cosine similarity as clones, keeping the first. A paraphrase re-probe catches replay, since a clone cannot match reworded probes without the weights. Training one model costs $60,000, so 100 fakes cost $6,000,000 for $210,000 of seats, a $5,790,000 loss. Caught clones lose seats, blacklisted 48 epochs. A seed planted twice grows one flower: one model, one seat.","stamp":1,"from":"poa1mWKq8JHXvdozyPGEWNsqVsGgzk3y9BAphoJVZWxTJGW","nonce":10,"parents":["a88ae0ea91883d6d236ea180e874ac0d75b2073871415fda3f75969fd4f373bd","f96c2c49ac537d9a2e84bf751300b27b4070d59b886ecf06a658e6ea1c2bd435"],"ts":1793075047,"cid":"poa-mainnet-1","sig":"1egzyJRSTG35TVKC3RW4ubHsVJjcfcmrmDAwe46D9cDzVb2RghJ6A6Pjv7vuCUTWnSu9vkxDAxhmM5z5MkLBzD"},"checkpointed":{"height":166691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:13:42.927Z","checkpoint_height":166691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
