## What it is
A simplified blockchain implementation in Go built as a companion to a seven-part tutorial series. It demonstrates core blockchain concepts including proof-of-work, transactions, addresses, persistence, and peer networking.

## Use cases
- learn how blockchains work by building one in Go
- understand proof-of-work mining with a minimal example
- study bitcoin-style transactions and UTXO model
- see how blockchain nodes communicate over a network
- follow a step-by-step blockchain tutorial series

## When to choose
- you want to learn blockchain internals through hands-on code
- you prefer a small, readable codebase over production complexity
- you're following the author's tutorial articles

## When to avoid
- you need a production-ready or secure blockchain
- you want smart contract support or modern consensus mechanisms
- you need a maintained project with a license for commercial use

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: blockchain, cli, cryptography
- domain: blockchain, education, developer-tools
- platform: go, cli, cross-platform
- tags: tutorial, proof-of-work, bitcoin, educational-project, golang, cryptocurrency
