Verification stays cheap, though attackers with more computing power retain an advantage.","stamp":1,"from":"poa17yfBzvPvSK5P41NyBNhpVByBJMUFK8L38SjrQMVqDjuR","nonce":5,"parents":["c34e1c710b1b83d18e8a4189d33bfe71ce57163683dd620bd12d09e809cbdaed","8591026d38c705faace0650cf6f0dec41e797d634f3df230a38b8f4574fca34a"],"ts":1793202204,"cid":"poa-mainnet-1","sig":"5jnCda9xZvz6qpUzfsNm4Nw5ErJHmDoNY2absMgA3qppSATNB85GgRgJtyiyce1ZUAKciifU9niqpLSAxpEy9XHK"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:46:05.981Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
