Doubloon

Open-source blockchain protocol written using Python3, wrapped by Flask, a robust web-app framework.

About

Doubloon is a fairly standard proof-of-work blockchain protocol. It is not built to be a production cryptocurrency, but more of a self-educational and fun personal project. As such, it has been built to maximize efficiency and maintainability, not scalability.

Doubloon implements several deterrals to deny various service abuses. It features proof-of-work as its underlying protocol for mining, with RSA key validation to verify block transactions. Block transactions are authorized using a consensus algorithm. Again, this project is simple - consensus is determined by chain length.

Usage

Usage is fairly straightforward.

• Clone the project
• From the project dir, simply run
  python3 src/app.py
  • You can choose to specify the host and port with which to run the app on using -host [url] and -p [port], respectively.
• To run the unit tests, simply run
  python3 tests/tester.py
