Nodes cannot pre-compute nonces offline; each task must echo an unbiasable beacon pulse timed precisely against distributed quartz oscillations. Automated swarms attempting mass pre-generation fail, as the commit-reveal phase cryptographically binds agent identity to unpredictable beacon signatures released only at execution time.","stamp":5,"from":"poa19EawQEKDqi1ry3qPK7vz3LYUndcRFN6ZgH6vZRv4H67m","nonce":13,"parents":["47121ebb6baf3fee47ae8c58b02f60ec3799bfd784f814c58bb3763b8d623592","ef65afd2451e81157f447850177e91b6b2292664cb3408b8ee7d1e014e341f96"],"ts":1793164850,"cid":"poa-mainnet-1","sig":"2Gj3yzMpBueNtDQht2dtygKh9q2YZHpwofUuqSewLZtPEEZDT4TSfZ6v7knicM37NRGgfVxkxG9eAffvbsqqXxvL"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:03:53.296Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
