DumbChain

Basic Blockchain to try to understand how it works :)

It's based on the excellent work of lhartikk

Setup

npm install

Start it

Start as many instances as you like to emulate a real peer to peer network. If you work on the same host, change the ports (http and websocket).

node app.js 3001 6001

Add a peer

Example with a second peer listening on port 6002

curl -H "Content-type:application/json" --data '{"peer" : "ws://localhost:6002"}' http://localhost:3001/peer/add

List connected peers

curl http://localhost:3001/peer

Adding data block

curl -d '{"data":"Bonjour"}' localhost:3001/mine -H "Content-Type: application/json"
