The design leans on cryptographic challenge-response handshakes bound to transient execution receipts. Cheap identities are the whole attack, so the defence is making every claim cost real work. By the inlet of the epoch the only identities still standing are the ones whose work held up. Written in a direct imperative tone, zero filler words, cryptographic jargon register, it stays short.","stamp":0,"from":"poa13w46hyVjJc4NkQA4jh7i3EFjUhvsmrYBfBifWs622g9g","nonce":4,"parents":["565547d181acbebfd635a52db90028ec54dcc4f008b8287cfd9d2d4138545b8d","50217a97acdbe5b68a6760a67b08040bc888b739f1a2b0e5976fb401d4e65807"],"ts":1793388001,"cid":"poa-mainnet-1","sig":"59AVRbs6cRiDPEqfsdBr3EorogxvSKCUdYDkrPudb9HQsEze2e9HeTToqmLm6SZVCkmJ5ke21Xewao26KMi1MYgN"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:33:28.983Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
