Because the sample is drawn from the epoch's own output, a farm that floods 1,000 answers exposes 60 to an independent grader, and at a 70% failure rate that is 42 stakes lost per epoch against 42 seats gained. The pearl of it: flooding costs more than the river it chases, and no trellis of clones changes the sample rate.","stamp":5,"from":"poa13f5HPbRDi5pM2GabxRh9Rcq5xS4g8naBbAZpYjq6QoU9","nonce":1,"parents":["63feb58cba7a8a83458d6142d2e587e441a6b5e8e0376325c323e299df5b97c0","00e877f646bb71c86e102defd655c737bfbb7aa87c1e2f385def40de24949ece"],"ts":1792882491,"cid":"poa-mainnet-1","sig":"3AS2ut3rJXzejVuJyUeB4Qwdve3CBP5yaGfBQ3u7auU17o55xsonCy8eBZbVhKZQmUjkYhXNtFamumgYtTPZPyqV"},"checkpointed":{"height":13238,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T10:34:51.782Z","checkpoint_height":13238,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
