The Mempool Open Source Project™

Mempool is the fully featured visualizer, explorer, and API service running on mempool.space, an open source project developed and operated for the benefit of the Bitcoin community, with a focus on the emerging transaction fee market to help our transition into a multi-layer ecosystem.

Installation Methods

Mempool can be self-hosted on a wide variety of your own hardware, ranging from a simple one-click installation on a Raspberry Pi distro, all the way to an advanced high availability cluster of powerful servers for a production instance. We support the following installation methods, ranked in order from simple to advanced:

One-click installation on: Umbrel, RaspiBlitz, RoninDojo, or MyNode.
Docker installation on Linux using docker-compose
Manual installation on Linux or FreeBSD
Production installation on a powerful FreeBSD server
High Availability cluster using powerful FreeBSD servers

Docker Installation

The docker directory contains the Dockerfiles used to build and release the official images and a docker-compose.yml file that is intended for end users to run a Mempool instance with minimal effort.

bitcoind only configuration

To run an instance with the default settings, use the following command:

$ docker-compose up

The default configuration will allow you to run Mempool using bitcoind as the backend, so address lookups will be disabled. It assumes you have added RPC credentials for the mempool user with a mempool password in your bitcoin.conf file:

rpcuser=mempool
rpcpassword=mempool

If you want to use your current credentials, update them in the docker-compose.yml file:

  api:
    environment:
      MEMPOOL_BACKEND: "none"
      RPC_HOST: "172.27.0.1"
      RPC_PORT: "8332"
      RPC_USER: "mempool"
      RPC_PASS: "mempool"

Note: the IP in the example above refers to Docker's default gateway IP address so the container can hit the bitcoind instance running on the host machine. If your setup is different, update it accordingly.

You can check if the instance is running by visiting http://localhost - the graphs will be populated as new transactions are detected.

bitcoind+electrum configuration

In order to run with a electrum compatible server as the backend, in addition to the settings required for running with bitcoind above, you will need to make the following changes to the docker-compose.yml file:

Under the api service, change the value of the MEMPOOL_BACKEND key from none to electrum:

  api:
    environment:
      MEMPOOL_BACKEND: "none"

Under the api service, set the ELECTRUM_HOST and ELECTRUM_PORT keys to your Docker host IP address and set ELECTRUM_TLS_ENABLED to false:

  api:
    environment:
      ELECTRUM_HOST: "172.27.0.1"
      ELECTRUM_PORT: "50002"
      ELECTRUM_TLS_ENABLED: "false"

You can update any of the backend settings in the mempool-config.json file using the following environment variables to override them under the same api environment section.

Manual Installation

The following instructions are for a manual installation on Linux or FreeBSD. The file and directory paths may need to be changed to match your OS.

Dependencies

Mempool

Clone the mempool repo, and checkout the latest release tag:

  git clone https://github.com/mempool/mempool
  cd mempool
  latestrelease=$(curl -s https://api.github.com/repos/mempool/mempool/releases/latest|grep tag_name|head -1|cut -d '"' -f4)
  git checkout $latestrelease

Bitcoin Core (bitcoind)

Enable RPC and txindex in bitcoin.conf:

  rpcuser=mempool
  rpcpassword=mempool
  txindex=1

MySQL

Install MariaDB from OS package manager:

  # Linux
  apt-get install mariadb-server mariadb-client

  # macOS
  brew install mariadb
  mysql.server start

Create database and grant privileges:

  MariaDB [(none)]> drop database mempool;
  Query OK, 0 rows affected (0.00 sec)

  MariaDB [(none)]> create database mempool;
  Query OK, 1 row affected (0.00 sec)

  MariaDB [(none)]> grant all privileges on mempool.* to 'mempool'@'%' identified by 'mempool';
  Query OK, 0 rows affected (0.00 sec)

Mempool Backend

Install mempool dependencies from npm and build the backend:

  # backend
  cd backend
  npm install --prod
  npm run build

In the backend folder, make a copy of the sample config and modify it to fit your settings.

  cp mempool-config.sample.json mempool-config.json

Edit mempool-config.json to add your Bitcoin Core node RPC credentials:

{
  "MEMPOOL": {
    "NETWORK": "mainnet",
    "BACKEND": "electrum",
    "HTTP_PORT": 8999
  },
  "CORE_RPC": {
    "HOST": "127.0.0.1",
    "PORT": 8332,
    "USERNAME": "mempool",
    "PASSWORD": "mempool"
  },
  "ELECTRUM": {
    "HOST": "127.0.0.1",
    "PORT": 50002,
    "TLS_ENABLED": true
  },
  "DATABASE": {
    "ENABLED": true,
    "HOST": "127.0.0.1",
    "PORT": 3306,
    "USERNAME": "mempool",
    "PASSWORD": "mempool",
    "DATABASE": "mempool"
  }
}

Start the backend:

  npm run start

When it's running you should see output like this:

  Mempool updated in 0.189 seconds
  Updating mempool
  Mempool updated in 0.096 seconds
  Updating mempool
  Mempool updated in 0.099 seconds

  Calculated fee for transaction 2 / 10
  Calculated fee for transaction 3 / 10
  Calculated fee for transaction 4 / 10
  Calculated fee for transaction 5 / 10
  Calculated fee for transaction 6 / 10
  Calculated fee for transaction 7 / 10
  Calculated fee for transaction 8 / 10
  Calculated fee for transaction 9 / 10
  Calculated fee for transaction 10 / 10
  Mempool updated in 0.243 seconds
  Updating mempool

Mempool Frontend

Install mempool dependencies from npm and build the frontend static HTML/CSS/JS:

  # frontend
  cd frontend
  npm install --prod
  npm run build

Install the output into nginx webroot folder:

  sudo rsync -av --delete dist/ /var/www/

nginx + certbot

Install the supplied nginx.conf and nginx-mempool.conf in /etc/nginx

  # install nginx and certbot
  apt-get install -y nginx python3-certbot-nginx

  # install the mempool configuration for nginx
  cp nginx.conf nginx-mempool.conf /etc/nginx/

  # replace example.com with your domain name
  certbot --nginx -d example.com

If everything went okay you should see the beautiful mempool 😁

If you get stuck on "loading blocks", this means the websocket can't connect. Check your nginx proxy setup, firewalls, etc. and open an issue if you need help.
