This is the source code for my post on Building a Blockchain.

Installation

  1. Make sure Python 3.6+ is installed.
  2. Install pipenv.
$ pip install pipenv
  1. Create a virtual environment and specify the Python version to use.
$ pipenv --python=python3.6
  1. Install requirements.
$ pipenv install
  1. Run the server:
    • $ pipenv run python blockchain.py
    • $ pipenv run python blockchain.py -p 5001
    • $ pipenv run python blockchain.py --port 5002

Docker

Another option for running this blockchain program is to use Docker. Follow the instructions below to create a local Docker container:

  1. Clone this repository
  2. Build the docker container
$ docker build -t blockchain .
  1. Run the container
$ docker run --rm -p 80:5000 blockchain
  1. To add more instances, vary the public port number before the colon:
$ docker run --rm -p 81:5000 blockchain
$ docker run --rm -p 82:5000 blockchain
$ docker run --rm -p 83:5000 blockchain
