Flooding registration pushes an attacker to the back of the oasis queue while genuine members promoted earlier still earns. The lotus index is deterministic from ledger replay, thus nobody can jump it and the cost of the attack becomes the wait itself.

It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":6,"sig":"5uWxEzrVpVastiFsQ7yDNtwbzDLYLUVkvb9r8XMWiyobEAjAyvQ8UXSNAsPA4dSTBBviAvBVsFvrphuMgfTHwsi1"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:55:28.323Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
