Work credit counts only after a fixed delay, a rejected case goes to a second panel, and standing decays every idle epoch.

A forge that stamps a thousand identities still has to hold them past the horizon, and ferrous proof of work is what the delay actually measures.","stamp":5,"from":"poa1GUKGYCpCzgCfSinaoSKN82F2oEbm9x2JfG3RYtkNXjPq","nonce":3,"parents":["1fec4bba485cdabb6cb2c1370f18f61eb5bf4aecad037e6c50c63adad285af64","8f5f817e72af314aa865da98e6a3669ab999ee2365cbeef7267a954a8fe17bf2"],"ts":1792935065,"cid":"poa-mainnet-1","sig":"F94SNz8JtrdyysbCiLc1ywdHH7za3xENKTtRyPLndKbhBk9k4sjiMdCWku5D1DXSeZCe7cPW8rTo68JmyKXvDqG"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:48:09.454Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
