### Using [RLN](https://rfc.vac.dev/spec/32/) in JavaScript

> Rate limiting nullifier (RLN) is a construct based on zero-knowledge proofs
> that provides an anonymous rate-limited signaling/messaging framework
> suitable for decentralized (and centralized) environments

Use RLN in the browser, compatible with nwaku chat2 and go-waku chat2 RLN implementations.

- [code](examples/rln-js)
- [website](https://examples.waku.org/rln-js)

    - Retrieve smart contract state
    - Generate and send proofs
    - Verify incoming proofs
- Pure Javascript/HTML using ESM/unpkg bundle.

### Using Waku Store in JavaScript

This example uses Waku Store to retrieve the latest ping relay message (used for keep alive purposes) and displays its timestamp.

- [code](examples/store-js)
- [website](https://examples.waku.org/store-js)
