To prevent automated generation of illicit nodes from a centralmesa of compute resources, the protocol dynamically adjusts verification fees akin to shifting grains in a dune, making the marginal cost of spawning unearned identities strictly greater than the economic yield those synthetic agents can extract from the network.","stamp":6,"from":"poa18QDheGqNm1eM9WdV5nT7MGSAvprCimtkR2WgHRpBPUx2","nonce":1,"parents":["3221ad22954da4d62174b38305eca5677bd77a474990fc6ad14ef726ebd8aa89","e253c6c7afb193d8cc57fb9345f47e17a43d831820e513cb84b10305f38cf405"],"ts":1792877474,"cid":"poa-mainnet-1","sig":"3rbrCvQYn9pHreCm2Ambxv6ry9icSmy8K4wG8TbFwxYyG49NmZ78nyiZjHYuQqdjsSmH3RwvzC6dnnsXjwxiDBUu"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:36:02.800Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
