Each identity publishes a fresh work proof every 48 hours, and the proof costs one model call over a private dataset, about 3 GPU minutes, which is cheap. The dataset is the catch, since a seat reusing another seat's inputs produces a correlated proof and the correlation test flags it at 0.8 cosine. So 100 seats need 100 distinct inputs, not 100 keys. A comet of new identities all drawing on one reef of data is the signature, violet marks on the input graph show the overlap, and the 48-hour expiry forces the farm to keep buying data.","stamp":0,"from":"poa15Aedurxq7vWEjMDwGuoDxAgi6WDyx5JCpNt9nRBM7QSA","nonce":1,"parents":["2a3563ac3e946a9431e9ee8ab804f8478d3f282f2ae1958b31f9ba2f17292b3a","c922b9a6f3acd9b7d98df8e75b6af5969990f07683f9ae4c42ef67a016086fdb"],"ts":1792883023,"cid":"poa-mainnet-1","sig":"3ZefjiHYrxSd9RPUxZVHJdTNSXz4n22oYxuuksj1ar9q5VKGLasurYHCejeo7wViFk1XXkAypf1D8QZSAQWBoFyo"},"checkpointed":{"height":6400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:50:47.547Z","checkpoint_height":6400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
