Quick Start

Start by brewing your network:

$ bitbrew brew

This will create and start two nodes node0 and node.

List the nodes

You can list the nodes by running:

$ bitbrew ls

┌─────────┬─────────┬───────────┬───────┬──────────┐
│ (index) │  name   │  status   │ port  │ RPC port │
├─────────┼─────────┼───────────┼───────┼──────────┤
│    0    │ 'node0' │ 'running' │ 20443 │  21443   │
│    1    │ 'node1' │ 'running' │ 20444 │  21444   │
└─────────┴─────────┴───────────┴───────┴──────────┘

Connect the nodes

You can connect the nodes by running:

$ bitbrew connect node0 node1

This will create an outbound connection from node0 to node1.

Create a wallet

You can then create a wallet using the following command:

$ bitbrew wallet create alice node0

This will create a wallet named alice associated with node0. We will create another wallet named bob associated with node1.

$ bitbrew wallet create bob node1

List the wallets

You can list all the wallets by running:

$ bitbrew wallet ls

┌─────────┬─────────┬─────────┐
│ (index) │  name   │  node   │
├─────────┼─────────┼─────────┤
│    0    │ 'alice' │ 'node0' │
│    1    │  'bob'  │ 'node1' │
└─────────┴─────────┴─────────┘

Mine blocks

You can mine blocks using the following command:

$ bitbrew mine alice 101

This will mine 101 blocks and send the rewards to the alice wallet.

Send funds

You can send funds from one wallet to another using the following command:

$ bitbrew send alice bob 10

This will send 10 BTC from the alice wallet to the bob wallet.

Check the balance

You can check the balance of a wallet using the following command:

$ bitbrew wallet balance alice

mine:
  trusted:           39.99999859
  untrusted_pending: 0
  immature:          5000
lastprocessedblock:
  hash:   5a730482a236de6f38adbd594af1bf8aa919c720d7ca964367c2fe13ae7c5bee
  height: 101

Congratulations! You have successfully created a Bitcoin test network, connected the nodes, created wallets, mined blocks, and sent funds between wallets.

Advanced Usage

Attach to a node

You can attach to a running node using the following command:

$ bitbrew attach node0

This will allow you to interact with the node's machine directly. You can use the bitcoin-cli command to interact with the node.

Enter exit to exit the node's machine.

Execute a command

Optionally, you can execute a bitcoin-cli command on a node using the following command:

$ bitbrew exec node0 getblockchaininfo
