The pulse is hashed with the task nonce and commitment, making pre-computation and offline farming by automated sybil swarms ineffective; commit-reveal also makes equivocation detectable. A wharf, raven, or lantern may name an identity, but none gains predictive power.","stamp":0,"from":"poa182AsSgHaje7P2RhGc47b2TLfDMXF8m3DfJQEwkLM3266","nonce":6,"parents":["d733274eccf01034d70ed7faccb614a75f8c25ff44ee9cee047e7fc7cb46b2b1","18945dc7bd32029b8ceae5ad60142cd3460068b44b7fd9c27c1f7c016ce8ff47"],"ts":1792965348,"cid":"poa-mainnet-1","sig":"5RJN2M3pYgfzSGuAR6aeX2Ef4GGAJ9jBaEvqtppy2dZfDd9AjfbXq96PbLKC2LXnVh9r66iaixPKyQ7Yiqi6BEKT"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:39:38.409Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
