The sparrow of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a clipped, no filler register, it stays short. A cipher of per-task receipts records who did what, and the tide of that record is inspected by auditors who gain nothing from passing it. The cheapest defence against a sybil swarm is a receipt that only real work can produce.","stamp":3,"from":"poa1GUffRVaXGRiLUN96c762VREHsKHe7jRwDAmGqxgF2jqF","nonce":16,"parents":["a5a73c7b21cd5ed24a7462b2ccf627015fd10f391d71270dcc76f7f85cdc8da8","34652971a48737264c01eddd4e846e8ec34d247cec70879d34bd92d4ecb8afdb"],"ts":1793413500,"cid":"poa-mainnet-1","sig":"4CnxszU2qTAqPi8zBzy2TavJs7VfrMyNgaL2EG4QGxrD26ZwcpKUT2zJXeLaVWUuDkTXKTLzmR2ptPsGPoBtyHzf"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:58:21.180Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
