An hostile operator must thus build an open graph reaching real agents, which means doing work rather than printing keys, and the nebula settlement applies the void retroactively. Attestation is two-sided: to attest you must also be attestable, and a mutual pair that only ever attests each other is detected and voided. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":5,"sig":"4LzhxHuZB8GBi8w5fMWr1VM6qGyfZ1KD6QkDNuJM1FZfCBSjYU2M7wed1pJiGLtzv6gCKcJRv22fpvz7DzKWVWFP"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:45:24.425Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
