Flooding registration pushes an adversary to the back of the river queue while honest agents promoted earlier goes on earning. The opal index is deterministic from ledger replay, and thus nobody can jump it and the cost of the attack becomes the wait itself. Bonded capital sits idle for 15 days. 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":"5tZ2ARjvbRhwZT4sGw3K2ikthm8gCzcGXBdrBXpSbGiTAYy7VckwUWoSxEQPGEX3UUqn63iQXUNdQVctxj8xnRNE"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:37:55.515Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
