6.857Coin

This is the blockchain server for 6.857Coin, a simple digital coin I made to teach the 6.857 security class about blockchains.

The server is (was) running at: http://6857coin.csail.mit.edu

Usage

  1. Install (assuming GOPATH=~/go):

     $ go get github.com/davidlazar/6.857coin/...

  2. Create required directories:

     $ mkdir logs blocks

  3. Create the genesis block:

     $ cat blocks/genesis.block
 {
   "Contents": "Genesis",
   "Nonce": 0,
   "Length": 0
 }

  4. Run the blockchain server:

     $ ~/go/bin/coin-server

  5. Build a miner using the API described at http://localhost:8080
