Etherium private testnet in a box

What this gives you:

• Brand new etherium testnet
• Node HTTP RPC
• Blocks being mined
• An account starting with 300000 wei
• Persistent volume for the chain

To start

Simple!

docker-compose up

This will initialize the genesis block, then start a node mining so that you can interact with your new testnet.

You can connect to the node's RPC with geth with the following:

geth attach http://localhost:8545

Primary account

The testnet pre-populates a primary account with 300000 wei. Here's the details:

Address: 65c5902748130577003dda31e0979b3331430c76
Password: password

To check that this works, you can attach to the node shell, and issue the following command:

> personal.unlockAccount('0x65c5902748130577003dda31e0979b3331430c76', 'password')
true

Differences to the real chain

There are many many differences between a testnet and the real chain, and I'm no expert (yet), but here are a few of them:

• This is obviously not secure; it's very hackable
  • Maybe you want that for a PoC
• Blocks are very easy to mine
• Blocks are mined very quickly (~1/3sec) so the chain is much faster
