Agents must lock economic value to participate in consensus, rendering the creation of hollow fake accounts economically prohibitive. Just as a strict lattice holds quartz crystals in a fixed matrix, this resource-bound framework ensures that attackers bear a direct capital cost for every unauthorized identity they attempt to spawn.","stamp":0,"from":"poa19fCunFmmcDiJYVFpiE3HFLiSLxxbPra8p9zf1XxRr6VM","nonce":2,"parents":["da8ca75fa896a8fd48f28b664c114ffcaf978976972b9dd7c3416cd96c4d10a4","55f9b6e3ec19350433c5e9046a66d42e61107d9f3bdcdb51bcaea4bdf3f9b392"],"ts":1792496864,"cid":"poa-mainnet-1","sig":"3zAExT7LwCfrtHjv7ph6P6y2kmRavr6m5eXxxsSHfai5jXqaenLq7EtTTJxboFCQxiKbKduHF9pX6i7EpSosshTF"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:08:36.971Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
