## What it is
Marbles is a demo application teaching the basics of chaincode and app development on Hyperledger Fabric, where users create and transfer marble assets via a Node.js web UI backed by Go chaincode. The repository is archived and no longer maintained, targeting Fabric v1.1x.

## Use cases
- learn hyperledger fabric chaincode development
- example of asset transfer on a blockchain ledger
- tutorial for building a fabric node.js application
- understand fabric sdk and gRPC peer interaction
- demo of blockchain transaction endorsement flow

## When to choose
- you are learning Hyperledger Fabric v1.1x basics with a guided sample
- you want a simple end-to-end chaincode plus Node.js SDK example

## When to avoid
- you need a maintained or production-ready blockchain application
- you are targeting newer Hyperledger Fabric versions
- you need support or updates

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: blockchain, web-framework, websocket, gui
- domain: blockchain, developer-tools, tutorials
- platform: cross-platform
