## What it is
SimpleCoin is a minimal, intentionally insecure and incomplete blockchain cryptocurrency implementation in Python, meant as educational material. It includes a miner node (with proof-of-work mining and a Flask server) and a wallet for sending transactions.

## Use cases
- learn how blockchain works
- understand proof-of-work mining
- build a simple bitcoin clone
- study cryptocurrency transaction handling
- teach blockchain concepts with runnable code
- see how mining nodes communicate over HTTP

## When to choose
- you want a small, readable codebase to learn blockchain fundamentals
- you're teaching or self-studying how cryptocurrencies work internally
- you want a toy project to extend with your own experiments

## When to avoid
- you need a secure or production-ready cryptocurrency
- you want a complete Bitcoin implementation with full protocol compatibility
- you need performance, scalability, or real monetary value

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: blockchain, cryptography, http-server, developer-tools
- domain: blockchain, education
- platform: python, cross-platform, cli
- tags: educational, toy-project, bitcoin-clone, proof-of-work, mining, wallet, flask, cryptocurrency, python
