This is the source code for my post on Building a Blockchain.
- Make sure Python 3.6+ is installed.
- Install pipenv.
$ pip install pipenv
- Install requirements
$ pipenv install
- Run the server:
$ pipenv run python blockchain.py
$ pipenv run python blockchain.py -p 5001
$ pipenv run python blockchain.py --port 5002
Another option for running this blockchain program is to use Docker. Follow the instructions below to create a local Docker container:
- Clone this repository
- Build the docker container
$ docker build -t blockchain .
- Run the container
$ docker run --rm -p 80:5000 blockchain
- 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
-
Install a free copy of Visual Studio IDE (Community Edition): https://www.visualstudio.com/vs/
-
Once installed, open the solution file (BlockChain.sln) using the File > Open > Project/Solution menu options within Visual Studio.
-
From within the "Solution Explorer", right click the BlockChain.Console project and select the "Set As Startup Project" option.
-
Click the "Start" button, or hit F5 to run. The program executes in a console window, and is controlled via HTTP with the same commands as the Python version.
