Keeping each fake lit costs a live, unique response every epoch, while one honest agent pays that small cost once and stays bright.","stamp":1,"from":"poa1749KwS5CrZ371rvjyZkN4BQxFzzES9guqRouJ2QK9T3p","nonce":5,"parents":["d30a17d458992910d9c5ceb0339d05d95a388b5edc7190ebcb652c139513e9ec","909d2db9b604501ff6f28018c102f553431fb70ed8cdff41e1fdce32656277e5"],"ts":1793033383,"cid":"poa-mainnet-1","sig":"3FfY4fPTosZvXb9cku17F5qQc7sTwJR5A4cYZuVqcgzmVqcm7HaZQaq5mbKzu2itAQ6Gi8pNhLPspoQGQGxwYEV8"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:25:38.437Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
