## What it is
A tutorial repository showing how to write and publish your own blockchain in less than 200 lines of Go, with a simple web server for adding blocks. It includes follow-up lessons on networking, proof of work, proof of stake, IPFS, and P2P.

## Use cases
- learn how blockchains work by coding one in Go
- understand proof of work and proof of stake with example code
- build a minimal blockchain web server for experimentation
- teach blockchain fundamentals in a workshop
- explore P2P blockchain networking basics

## When to choose
- you want a short, hands-on introduction to blockchain internals in Go
- you prefer learning by reading and running minimal code
- you need teaching material for blockchain basics

## When to avoid
- you need a production-ready blockchain platform
- you require advanced features like smart contracts or consensus hardening
- you need actively maintained software with ongoing support

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: blockchain, http-server, developer-tools
- domain: blockchain, tutorials, education, developer-tools
- platform: go, cross-platform
- tags: blockchain-tutorial, go, proof-of-work, proof-of-stake, p2p, hands-on-learning, education, web-server
