go-waku-compose

Ready to use docker-compose to run your own go-waku full node:

• go-waku node running relay and store protocols with RLN enabled.
• Simple frontend to interact with your node and the network, to publish and receive messages.
• Grafana dashboard for advanced users or node operators.
• Requires docker-compose and git.

📝 0. Prerequisites

You need:

• Ethereum Sepolia WebSocket endpoint. Get one free from Infura.
• Ethereum Sepolia account with some balance <0.01 Eth. Get some here.
• A password to protect your rln membership.

There is .env.example available for you as a template to use for providing the above values. The process when working with .env files is to copy the .env.example, store it as .env and edit the values there.

cp .env.example .env
${EDITOR} .env

Make sure to NOT place any secrets into .env.example, as they might be unintentionally published in the Git repository.

🔑 1. Register RLN membership

The RLN membership is your access key to The Waku Network. Its registration is done onchain, and allows your go-waku node to publish messages in a decentralized and private way, respecting some rate limits. Messages exceeding the rate limit won't be relayed by other peers.

This command will register your membership and store it in keystore/keystore.json. Note that if you just want to relay traffic (not publish), you don't need one.

./register_rln.sh

🖥️ 2. Start your node

Start all processes: go-waku node, database and grafana for metrics. Your RLN membership is loaded into go-waku under the hood.

docker-compose up -d

🏄🏼‍♂️ 3. Interact with your go-waku node

• See http://localhost:3000/d/yns_4vFVk/go-waku-monitoring for node metrics.
• See localhost:4000. Under development 🚧

📬 4. Use the REST API

Your go-waku node exposes a REST API to interact with it.

# get go-waku version
curl http://127.0.0.1:8645/debug/v1/version
# get go-waku info
curl http://127.0.0.1:8645/debug/v1/info

Publish a message to a contentTopic. Everyone subscribed to it will receive it. Note that payload is base64 encoded.

curl -X POST "http://127.0.0.1:8645/relay/v1/auto/messages" \
 -H "content-type: application/json" \
 -d '{"payload":"'$(echo -n "Hello Waku Network - from Anonymous User" | base64)'","contentTopic":"/my-app/2/chatroom-1/proto"}'

Get messages sent to a contentTopic. Note that any store node in the network is used to reply.

curl -X GET "http://127.0.0.1:8645/store/v1/messages?contentTopics=%2Fmy-app%2F2%2Fchatroom-1%2Fproto&pageSize=50&ascending=true" \
 -H "accept: application/json"
