MobyMask Watcher P2P Network

Instructions to setup and deploy a watcher that connects to the existing watcher p2p network

Prerequisites

Laconic Stack Orchestrator (installation)
A publicly reachable domain name with SSL setup

This demo has been tested on a Ubuntu 22.04 LTS machine with 8GB of RAM

Setup

Clone required repositories:

laconic-so --stack mobymask-v2 setup-repositories --include github.com/cerc-io/MobyMask,github.com/cerc-io/watcher-ts,github.com/cerc-io/mobymask-v2-watcher-ts

# This will clone the required repositories at ~/cerc
# If this throws an error as a result of being already checked out to a branch/tag in a repo, remove the repositories mentioned in the next step and re-run the command

# Expected output:

# Dev Root is: /home/xyz/cerc
# Checking: /home/xyz/cerc/watcher-ts: Needs to be fetched
# 100%|#############################################################################################################################################| 9.96k/9.96k [00:05<00:00, 1.70kB/s]
# Checking: /home/xyz/cerc/mobymask-v2-watcher-ts: Needs to be fetched

# 100%|##############################################################################################################################################| 1.41k/1.41k [00:18<00:00, 76.4B/s]

Build the container images:

laconic-so --stack mobymask-v2 build-containers --include cerc/watcher-ts,cerc/watcher-mobymask-v2,cerc/mobymask

Check that the required images are created in the local image registry:

docker image ls

# Expected output:

# cerc/mobymask             local    9db3f1a69966   2 weeks ago      3.82GB
# .
# .

Deploy

Configuration

Create an env file mobymask-watcher.env:

touch mobymask-watcher.env

Add the following contents to mobymask-watcher.env:

# Domain to be used in the relay node's announce address
CERC_RELAY_ANNOUNCE_DOMAIN="mobymask.example.com"


# DO NOT CHANGE THESE VALUES
CERC_L2_GETH_RPC="https://mobymask-l2.dev.vdb.to"
CERC_DEPLOYED_CONTRACT="0x2B6AFbd4F479cE4101Df722cF4E05F941523EaD9"
CERC_ENABLE_PEER_L2_TXS=false
CERC_RELAY_PEERS=["/dns4/relay1.dev.vdb.to/tcp/443/wss/p2p/12D3KooWAx83SM9GWVPc9v9fNzLzftRX6EaAFMjhYiFxRYqctcW1", "/dns4/relay2.dev.vdb.to/tcp/443/wss/p2p/12D3KooWBycy6vHVEfUwwYRbPLBdb5gx9gtFSEMpErYPUjUkDNkm", "/dns4/relay3.dev.vdb.to/tcp/443/wss/p2p/12D3KooWARcUJsiGCgiygiRVVK94U8BNSy8DFBbzAF3B6orrabwn"]

Replace CERC_RELAY_ANNOUNCE_DOMAIN with your public domain name

Deploy the stack

laconic-so --stack mobymask-v2 deploy --cluster mobymask_v2 --include watcher-mobymask-v2 --env-file mobymask-watcher.env up

# Expected output (ignore the "The X variable is not set. Defaulting to a blank string." warnings):

This will run the mobymask-v2-watcher including:

A relay node which is in a federated setup with relay nodes set in the env file
A peer node which connects to the watcher relay node as an entrypoint to the MobyMask watcher p2p network. This peer listens for messages from other peers on the network and logs them out to the console

The watcher GraphQL endpoint is exposed on host port 3001 and the relay node endpoint is exposed on host port 9090

To list down and monitor the running containers:

laconic-so --stack mobymask-v2 deploy --cluster mobymask_v2 --include watcher-mobymask-v2 ps

# Check logs for a container
docker logs -f <CONTAINER_ID>

Check watcher container logs to get multiaddr advertised by the watcher's relay node and note it down for further usage:

laconic-so --stack mobymask-v2 deploy --cluster mobymask_v2 --include watcher-mobymask-v2 logs mobymask-watcher-server | grep -A 2 "Relay node started"

# The multiaddr will be of form /dns4/<CERC_RELAY_ANNOUNCE_DOMAIN>/tcp/443/wss/p2p/<RELAY_PEER_ID>

Web App

To be able to connect to the relay node from remote peers, it needs to be publicly reachable. Configure your website with SSL and the https traffic reverse proxied as:

/graphql to port 3001 (watcher GQL endpoint)
/ to port 9090 (relay node)

For example, a Nginx configuration for domain mobymask.example.com would look something like:

server {
  server_name mobymask.example.com;

  location /graphql {
    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_pass http://127.0.0.1:3001;
    proxy_read_timeout 90;
  }

  # https://nginx.org/en/docs/http/websocket.html
  location / {
    proxy_pass http://127.0.0.1:9090;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

    # set a large timeout to avoid websocket disconnects
    proxy_read_timeout 86400;
  }

  listen [::]:443 ssl ipv6only=on; # managed by Certbot
  listen 443 ssl; # managed by Certbot
  ssl_certificate /etc/letsencrypt/live/mobymask.example.com/fullchain.pem; # managed by Certbot
  ssl_certificate_key /etc/letsencrypt/live/mobymask.example.com/privkey.pem; # managed by Certbot
  include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
  ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
  if ($host = mobymask.example.com) {
    return 301 https://$host$request_uri;
  } # managed by Certbot

  listen 80;
  listen [::]:80;

  server_name mobymask.example.com;
  return 404; # managed by Certbot
}

To test the web-app, either visit https://mobymask-lxdao-app.dev.vdb.to/ or follow web-app.md to deploy the app locally that hits your watcher's GQL endpoint

Connect a browser peer to the watcher's relay node:

Click on debug panel on bottom right of the homepage
Select <custom> in Primary Relay dropdown on the right and enter the watcher relay node's multiaddr
Click on UPDATE to refresh the page and connect to the watcher's relay node; you should see the relay node's multiaddr in Self Node Info on the debug panel
Switch to the GRAPH (PEERS) tab to see peers connected to this browser node and the GRAPH (NETWORK) tab to see the whole MobyMask p2p network

Perform transactions:

An invitation is required to be able to perform transactions; ask an existing user of the app for an invite
In a browser, close the app if it's already open and then open the invite link
From the debug panel, confirm that the browser peer is connected to at least one other peer
Check the status for a phisher to be reported in the Check Phisher Status section on homepage
Select Report Phisher option in the Pending reports section, enter multiple phisher records and click on the Submit batch to p2p network button; this broadcasts signed invocations to peers on the network, including the watcher peer

Check the watcher container logs to see the message received:

docker logs $(docker ps -aq --filter name="mobymask-watcher-server")

Troubleshooting

If you don't see any peer connections being formed in the debug panel on https://mobymask-lxdao-app.dev.vdb.to/, try clearing out the website's local storage and refreshing the page
