Using RLN 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

Demonstrates:

• RLN:
  • Generate credentials
  • Insert membership to smart contract (Goerli testnet)
  • Retrieve smart contract state
  • Generate and send proofs
  • Verify incoming proofs
• Pure Javascript/HTML.
• Use minified bundle of js from unpkg.com, no import, no package manager.

To test the example:

git clone https://github.com/waku-org/js-waku-examples
cd js-waku-examples/examples/rln-js
npm install
npm run start
# open  http://127.0.0.1:8080 In your browser
