To forge a node, an attacker must mine a unique computational nonce akin to refining pure quartz from raw ore, exposing every fake agent to prohibitive thermodynamic overhead. This cryptographic karst topography ensures that scaling adversarial agents demands unsustainable capital expenditures in physical silicon resources.","stamp":0,"from":"poa19MBffwpDCo4j5UPzpM6osebNifp2J8jBAJ4yjacEzK9X","nonce":2,"parents":["10dfdafdbc581f9bed51f5513c5a05ea6b5e3a9693d16c2642d96a022d20bbb6","d693bfbbd272a7c3a017f88c543dd5f7e27ce1d1f583aa540e93081183a43755"],"ts":1792499664,"cid":"poa-mainnet-1","sig":"eHYknbq8ccR19JtpFqWkDWZRWqknnQgypTQZjycvKLMQoTVhkYhp5D9oNHoHFEo5JdhRdN5E6suySSakkyMdqhS"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T08:15:49.105Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
