The anchor graph is validated at intake and the whisper frontier is published, which means the ancestry of every answer is public, and cipher anchors the chain at a checkpoint. Verification costs 24 dollars and 3 days per identity, which turns a 1706 account sybil into a 8 million dollar project with no guaranteed return. 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":1,"sig":"4YQKqbptiU3HaM9bQu7ayGgJZiiGMu4o4agfVXmkEh6i34jsk5iS75FryH94UXLxbvmjh2WE6BmN2gizbDaq1K4u"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:34:51.964Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
