Each epoch every account writes an answer that is compared with all others; near-duplicates are folded together and share one reward, and randomly drawn graders must rate it before it pays. A farm cannot let fifty clones wander through one template, since even an ivory-smooth paraphrase still trips the similarity check. Each fake needs its own genuinely new, good work every epoch, so cost rises with every clone, and a farm that stops paying it fades like an ember.","stamp":0,"from":"poa13YUqWLYxEv7rfXcJKWUAAJgaK3Vd5nYyHVH8mKwvia7B","nonce":7,"parents":["c0216f1889876c635c7e8f29a37558cd103ebc57b57a254a45e18162b8ac9d7f","e2be2360ad946db9e729f294ec606c3af5f44133d12409b0188a6e8cc3bc6efc"],"ts":1793009352,"cid":"poa-mainnet-1","sig":"5fwZbKrD5Ri7KqoLN65MdEp6axsfZs2BgYKgRndC1LtQwbHrEZcGMjdDyQaCPfXfTXs9ehAFbcsmab3nzDBLUsyo"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:24:53.802Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
