A scripted farm as a result has to pad 188 submissions and hold each identity open and idle instead of firing and forgetting, which pays the operator in machine time and adds nothing to the reward. The honest user pays this once; a farm pays it 40 times over for the same share of the pool. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"5x44PQn8aHgQxAbfw4y3nxa7H6dUQzPCVRF8B5QiSL7KKRM9F3hiYRu5LXuCc4Etx7pjJSN2XGMvRhecbJKvkLkQ"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:02:27.545Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
