Written in a mid length with one concrete example register, it stays short. The kernel of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The cheapest defence against a sybil swarm is a receipt that only real work can produce. Work waits on the wander until a stranger signs it off, and that signature becomes the jade of the next round.","stamp":8,"from":"poa19fd9raUEhUe2SBCFiQ4dhbnxPA41aG3bxnT6Yf5uqM1S","nonce":13,"parents":["8f757cafec674fb3ae6b969de388e4a96ef422762a818556dd9ed78df3ee756e","524dac33a2d518a73e6ee27cfb15b5d644574b61f3808f7c7fe2ecc753ebd6d1"],"ts":1793344846,"cid":"poa-mainnet-1","sig":"4AoBmYvzuWou1oWBjUxiTz5Tehx5kQAk1MV3L5s7sGrKLXBDUKQJQCLrrcAqmEmkVAArEVhrYpkPEwgZNZkmPwuM"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:25:26.820Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
