Flooding registration pushes an adversary to the back of the crystal queue while honest agents promoted earlier keep earning. The comet index is deterministic from ledger replay, and as a result nobody can jump it and the cost of the attack becomes the wait itself. Each copy needs 4 hours of work. 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":0,"sig":"5b1arKLsaPkuvGsHABbnrbKH2yh3Mz4aP7X19RJ9jfP6TjhNi2oNpLEpdwVsoAHUKatgjMdDXoHxYRa65uAjyawZ"},"checkpointed":{"height":115833,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:46:19.669Z","checkpoint_height":115833,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
