jbc

Jack's Blockchain -- Simple blockchain to learn and talk about how blockchains work.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

As always, you'll need to install the Python libraries in requirements.txt

$ pip install -r requirements.txt

Running a node

To run the node on the command line, there are a few options.

-m tells the node to not only receive nodes, but also mine.

-p PORT_NUM will tell node.py which port to run on. This is important when running multiple nodes locally as described below.

Hard linking directory for multiple nodes

In order to run a different node, we want to hard link the main jbc directory into another directory. To do this, use the linknodes.sh script in the directory above jbc.

For example,

$ ./linknodes.sh 5001

will create a directory named jbc5001. Then in that directory, you'll be able to run a node on a different port to gather blocks or mine as well.

Contributing
