Simple blockchain written in python
|
||||||
|
|
||||||
This is the source code for my post on [Building a Blockchain](https://medium.com/p/117428612f46).
|
|
||||||
|
|

2. Install [pipenv](https://github.com/kennethreitz/pipenv).
|
2. Install [poetry](https://github.com/sdispater/poetry).
|
||||||
|
3. Install requirements
|
||||||
|
```
|
||||||
|
$ poetry install
|
||||||
|
```
|
||||||
|
|
||||||
```
|
4. Copy `.env.example` to `.env`
|
||||||
$ pip install pipenv
|
|
||||||
```
|
5. Start some nodes:
|
||||||
3. Install requirements
|
* `$ poetry run flask run -p 5000`
|
||||||
```
|
* `$ poetry run flask run -p 5001`
|
||||||
$ pipenv install
|
|
||||||
```
|
|
||||||
|
|
||||||
4. 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:
|
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
|
1. Build the docker image
|
||||||
2. Build the docker container
|
|
||||||
|
|
||||||
```
|
```
|
||||||
$ docker build -t blockchain .
|
$ docker-compose build
|
||||||
```
|
```
|
||||||
|
|
||||||
3. Run the container
|
2. Run the nodes
|
||||||
|
|
||||||
```
|
```
|
||||||
$ docker run --rm -p 80:5000 blockchain
|
$ docker-compose up -d
|
||||||
```
|
```
|
||||||
|
|
||||||
4. To add more instances, vary the public port number before the colon:
|
4. To add more nodes, add a new service to the `docker-compose.yml` file
|
||||||
|
and adjust the port number.
|
||||||
|
|
||||||
```
|
```yaml
|
||||||
$ docker run --rm -p 81:5000 blockchain
|
node2:
|
||||||
$ docker run --rm -p 82:5000 blockchain
|
build: .
|
||||||
$ docker run --rm -p 83:5000 blockchain
|
ports:
|
||||||
|
- 5002:80
|
||||||
```
|
```
|
||||||
|
|
||||||
## Installation (C# Implementation)
|
## Credits
|
||||||
|
|
||||||
1. Install a free copy of Visual Studio IDE (Community Edition):
|
|
||||||
https://www.visualstudio.com/vs/
|
|
||||||
|
|
||||||
2. Once installed, open the solution file (BlockChain.sln) using the File > Open > Project/Solution menu options within Visual Studio.
|
|
||||||
|
|
||||||
3. From within the "Solution Explorer", right click the BlockChain.Console project and select the "Set As Startup Project" option.
|
|
||||||
|
|
||||||
4. 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.
