 <AccordionItem title="What are Rate Limiting Nullifiers (RLN)?">
   <a href="/learn/concepts/protocols#rln-relay">Rate Limiting Nullifier</a> is a zero-knowledge (ZK) protocol enabling spam protection in a decentralized network while preserving privacy. Each message must be accompanied by a ZK proof, which <a href="/learn/concepts/protocols#relay">Relay</a> nodes verify to ensure the publishers do not send more messages than they are allowed. The ZK proof does not leak any private information about message publishers - it only proves they are members of a set of users allowed to publish a certain number of messages per given time frame.
