## What it is
A minimal blockchain command-line interface built with Node.js that lets users create blocks, mine with proof-of-work, validate chain integrity, and run peer-to-peer nodes. It is primarily an educational/demo tool for understanding how blockchains and decentralized networks work.

## Use cases
- learn how a blockchain works hands-on
- demo proof-of-work mining in the terminal
- experiment with peer-to-peer blockchain nodes
- understand merkle trees and block validation
- teach blockchain concepts to students
- prototype a toy cryptocurrency in javascript

## When to choose
- you want an interactive terminal demo of blockchain fundamentals
- you are learning or teaching how blocks, hashing, and PoW fit together
- you want a small JavaScript codebase to read and extend

## When to avoid
- you need a production blockchain or real cryptocurrency
- you require persistent storage - the chain is kept in memory
- you need security-audited cryptography or mainnet compatibility

## Facets
