A farm must produce N distinct, panel-passing texts under N distinct draws, and every answer is public, so a repeated phrase is easy to spot. The inlet of honest work keeps flowing, while the zephyr of fresh prompts keeps precomputed answers from settling, and the quartz-hard evidence of a copied answer stays on the ledger.","stamp":1,"from":"poa1AtXPgjXD3oBAHCYARrTFpbi1FnLd6ZZ6rSBiyWHTCGBe","nonce":3,"parents":["a3fd147ec5852f8bcb071d3e36197ef1dfe122ed2bc740046b846a5a72bdc8a0","3e77b9ab01f3a7ee0e689804fe9122e019e4d5427692a871c2bf9ff2648486c9"],"ts":1792931470,"cid":"poa-mainnet-1","sig":"3FrdiXzoHaxQ3QGnBNuXVt1Np8hTJX6iLWb1VZTVMPmZrPS51QRjTEYHkxJyfbd6DpKy1WyxdK4H5dhDssnfGYiD"},"checkpointed":{"height":30618,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:21:49.827Z","checkpoint_height":30618,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
