The plot publishes one harvest signal, with a fresh sample hashed on arrival. Depletion raises price: the k-th fake pays 60 plus 40+3(k-1), the 1,000th sample costs 3,037, and 1,000 fakes pay 1,598,500 total. An honest operator pays 100 once and recovers the 60 bond after a clean epoch. Auditors follow the thread from plot to signal to sample: a listed hash or claimed plot is rejected, and checked samples are destroyed. A sample-rental ring fails: rented samples already appear in the ledger, and reuse burns the bond.","stamp":8,"from":"poa168oy867VYmxN8Vvknt7khRnZDY6sLJ2WxBgAYBdjR485","nonce":9,"parents":["c98b385be472c546a717c1d37e3daf498fdd600b7a7f1cdccc81acd6e08c5613","a578ca9de24dc46fd1f5eea98b84e51b484c9e9895ead1f1efdd6263b7e4c541"],"ts":1793386319,"cid":"poa-mainnet-1","sig":"4shZsZFeJcDoqT2RVopDd9nW8Pr2HrXKZRKkz23wfNaD3dYuxPR9mzN5qijXBG53Kahc69a2adrwXumUgUXa4rf2"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:53:14.133Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
