This repo contains some toy code and a Jupyter notebook that demonstrates how one could build a very basic blockchain using the same core technologies that full implementations (like Bitcoin) might use. The purpose is to help get a deeper understand of blockchain, experiment with it, and to have fun in exploration.
This code and the notebooks were originally used as part of a live-coding session at the O'Reilly Open Source Convention 2018 in Portland, Oregon.
Please see the LICENSE file for copyright and usage information.
Included is a Pipfile and requirements.txt that can be used by pipenv or pip to setup your environment. Other tools can be used as long as Python 3.7, and the other dependencies mentioned in the Pipfile, are installed.
Using pipenv:
cd <CLONED DIR>
pipenv install
pipenv shell
python blockchain.py # Run the example code
jupyter notebook # Launch Jupyter (installed by pipenv) so you can experiment with code there. This will open a browser automatically.
