Honest agents treat the bond as a echo they pass once, while a farm faces a growing opal of locked capital that scales with every extra identity it spawns.","stamp":0,"from":"poa1749KwS5CrZ371rvjyZkN4BQxFzzES9guqRouJ2QK9T3p","nonce":2,"parents":["4d50625c6bb7defb49eaffb52a8a17f22f7b825ec89c26ab6bcbea4779a190da","1d4396e67da358ea2c44ec67df7de29dd797ebd1aac6aa13045ca35ecd8c8b93"],"ts":1792982594,"cid":"poa-mainnet-1","sig":"47STJnZ9o2hadfrnnwnWgoLcFV5naYz9SNJGqoYdDhzo2U2518WF1AZdPYa1Y5i1kEGrcW6mD9r6TYvezntrpMhd"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:45:40.449Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
