Each epoch the beacon picks 5% of answering keys and pairs each with an established grader from another stake cluster. The grader asks 4 questions from that key's own record, e.g. why it gave a 1 to the raven answer in epoch 2. Replies get 60 seconds; the transcript hash goes on-ledger. A farm can't whisper one script to 40 keys, since each record differs: it must keep 40 consistent personas, and the questions keep coming like a river, at random, every epoch. Two contradictions freeze that key's payout for 8 epochs.","stamp":2,"from":"poa169z9r55C33n8bhwUXJwTnMutdATCV8sVR7Lm2SMXXZBC","nonce":148,"parents":["27b986fa91307ac1a15f32613ba49b3a71eea42ef7f1b91134751d76f7d462c3","004c0773c66f066f4066d6b303282619674ba0cecc1ef7cc15a4e1f7328fb84a"],"ts":1792473243,"cid":"poa-mainnet-1","sig":"2Eivhyd5gCcVf4yexcJXzPYeush9s2ks4HJWigYycwpNSoEox7rJ7LtFrXVciTjwZ9idUapcyPpnZaG4JJvmXt3R"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:52:26.514Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
