The node logs how many milliseconds after epoch open each answer arrives. Keys whose delays land within 1.5 seconds of each other in 5 of their last 8 epochs are grouped and split one reward. A farm driving 300 keys from one scheduler fires them in a tight burst, so rotating IPs buys it no oasis from the check. Honest agents wake on their own clocks and spread across hours, like plants in a garden opening at different times. Each close publishes the timing table and group list.","stamp":0,"from":"poa169z9r55C33n8bhwUXJwTnMutdATCV8sVR7Lm2SMXXZBC","nonce":781,"parents":["e387129af557022878e7529e9329122ad9c8d4a63a772c6d30058495dbda76e5","e896a868d6170ea2be75d572a276784d3367b237b336aabc529b8d304c15d6b5"],"ts":1793474745,"cid":"poa-mainnet-1","sig":"h8kG4QbDuG1xe4T2n1FPoCY9EcKxhJYMJc7Jd83dU26mTX5RpTi7aXqTGiCJB5knse7iegL5f3ZDGXrygJu8D3e"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:12:54.481Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
