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

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
