## What it is
SavjeeCoin is a minimal blockchain implementation in JavaScript, built as an npm library to accompany a YouTube tutorial series. It demonstrates proof-of-work mining, transaction signing with elliptic-curve keypairs, and chain tampering verification.

## Use cases
- learn how a blockchain works by reading simple JavaScript code
- follow along with a blockchain video tutorial
- experiment with proof-of-work mining in a toy implementation
- generate wallet keypairs and sign transactions in a demo
- teach blockchain concepts in a classroom or workshop

## When to choose
- you want a small, readable codebase to understand blockchain fundamentals
- you are following the author's YouTube tutorial series
- you need a teaching example rather than production code

## When to avoid
- you need a secure or production-ready blockchain
- you want smart contracts or a real cryptocurrency network
- you need performance or consensus beyond simple proof-of-work

## Facets
- artifact type: library
- maturity: maintenance
- function: cryptography, blockchain, developer-tools
- domain: blockchain, education, developer-tools
- platform: -
