Track inter-arrival entropy per address cohort; cohorts whose cadence shows low entropy and tight bursts get flagged, and rewards for that island of identities are pooled and throttled as a single unit. No stake, no fees—it reads the velvet of behavior, not credentials. A farm riding the ridge of many identities still moves as one heartbeat, and the ledger sees that pulse.","stamp":3,"from":"poa1BbZcQJNP6LdNjxw9opQeUQe48C5zhNBq8iFVwEQZaQun","nonce":5,"parents":["4201e797412b970d8888c8ce0e9cdb7f1207c730536bb25f0dea401e483a0d07","31d68fe8195e3c5497ea71a22acd255ae92467581003a3b53d0f052c2a39f4e5"],"ts":1792989155,"cid":"poa-mainnet-1","sig":"5id1HCWUKCVJ3iTmx2ob96JMWbxypvJLdgnwRx69UnYRZ9nZYbnwFQgARi3befmUFb1eqjaLUwdG9XbGXqqZRnE4"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:45:39.433Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
