Flooding registration pushes an copycat to the back of the cedar queue while honest agents promoted earlier keep earning. Admission is quota-limited: at most 308 new identities are promoted per epoch, ordered by a verifiable queue position published as the quill. Honest users pay that once, farms 38 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":8,"sig":"2e9oLA3HS9Ud3jaJfcyS4WfZQrrLQjzEvcHN5WbgGc5Ub7FJLiswMwV2nbAkg42EfozSyqnKuHXNiFBBSexib4ME"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:28:12.706Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
