WoT Relay

WOT Relay is a Nostr relay that saves all the notes that people you follow, and people they follow are posting. It's built on the Khatru framework.

Available Relays

Don't want to run the relay, just want to connect to some? Here are some available relays:

Prerequisites

  • Go: Ensure you have Go installed on your system. You can download it from here.
  • Build Essentials: If you're using Linux, you may need to install build essentials. You can do this by running sudo apt install build-essential.

Setup Instructions

Follow these steps to get the WOT Relay running on your local machine:

1. Clone the repository

git clone https://github.com/bitvora/wot-relay.git
cd wot-relay

2. Copy .env.example to .env

You'll need to create an .env file based on the example provided in the repository.

cp .env.example .env

3. Set your environment variables

Open the .env file and set the necessary environment variables. Example variables include:

RELAY_NAME="YourRelayName"
RELAY_PUBKEY="YourPublicKey" # the owner's hexkey, not npub. Convert npub to hex here: https://nostrcheck.me/converter/
RELAY_DESCRIPTION="Your relay description"
DB_PATH="/home/ubuntu/wot-relay/db" # any path you would like the database to be saved.
INDEX_PATH="/home/ubuntu/wot-relay/templates/index.html" # path to the index.html file
STATIC_PATH="/home/ubuntu/wot-relay/templates/static" # path to the static folder
REFRESH_INTERVAL_HOURS=24 # interval in hours to refresh the web of trust
MINIMUM_FOLLOWERS=3 #how many followers before they're allowed in the WoT
ARCHIVAL_SYNC="FALSE" # set to TRUE to archive every note from every person in the WoT (not recommended)
ARCHIVE_REACTIONS="FALSE" # set to TRUE to archive every reaction from every person in the WoT (not recommended)

4. Build the project

Run the following command to build the relay:

go build -ldflags "-X main.version=$(git describe --tags --always)"

5. Create a Systemd Service (optional)

To have the relay run as a service, create a systemd unit file. Make sure to limit the memory usage to less than your system's total memory to prevent the relay from crashing the system.

  1. Create the file:
sudo nano /etc/systemd/system/wot-relay.service
  1. Add the following contents:
[Unit]
Description=WOT Relay Service
After=network.target

[Service]
ExecStart=/home/ubuntu/wot-relay/wot-relay
WorkingDirectory=/home/ubuntu/wot-relay
Restart=always
MemoryLimit=2G

[Install]
WantedBy=multi-user.target

Replace /path/to/ with the actual paths where you cloned the repository and stored the .env file.

  1. Reload systemd to recognize the new service:
sudo systemctl daemon-reload
  1. Start the service:
sudo systemctl start wot-relay
  1. (Optional) Enable the service to start on boot:
sudo systemctl enable wot-relay

Permission Issues on Some Systems

the relay may not have permissions to read and write to the database. To fix this, you can change the permissions of the database folder:

sudo chmod -R 777 /path/to/db

6. Serving over nginx (optional)

You can serve the relay over nginx by adding the following configuration to your nginx configuration file:

server {
    listen 80;
    server_name yourdomain.com;

    location / {
        proxy_pass http://localhost:3334;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Replace yourdomain.com with your actual domain name.

After adding the configuration, restart nginx:

sudo systemctl restart nginx

7. Install Certbot (optional)

If you want to serve the relay over HTTPS, you can use Certbot to generate an SSL certificate.

sudo apt-get update
sudo apt-get install certbot python3-certbot-nginx

After installing Certbot, run the following command to generate an SSL certificate:

sudo certbot --nginx

Follow the instructions to generate the certificate.

8. Access the relay

Once everything is set up, the relay will be running on localhost:3334 or your domain name if you set up nginx.

Start the Project with Docker Compose

To start the project using Docker Compose, follow these steps:

  1. Ensure Docker and Docker Compose are installed on your system.

  2. Navigate to the project directory.

  3. Ensure the .env file is present in the project directory and has the necessary environment variables set.

  4. You can also change the paths of the db folder and templates folder in the docker-compose.yml file.

    volumes:
  - "./db:/app/db" # only change the left side before the colon
  - "./templates/index.html:${INDEX_PATH}" # only change the left side before the colon
  - "./templates/static:${INDEX_PATH}" # only change the left side before the colon

  5. Run the following command:

    # in foreground
docker compose up --build
# in background
docker compose up --build -d

  6. For updating the relay, run the following command:

    git pull
docker compose build --no-cache
# in foreground
docker compose up
# in background
docker compose up -d

This will build the Docker image and start the wot-relay service as defined in the docker-compose.yml file. The application will be accessible on port 3334.

7. Hidden Service with Tor (optional)

Same as the step 6, but with the following command:

# in foreground
docker compose -f docker-compose.tor.yml up --build
# in background
docker compose -f docker-compose.tor.yml up --build -d

You can find the onion address here: tor/data/relay/hostname

8. Access the relay

Once everything is set up, the relay will be running on localhost:3334.

http://localhost:3334
