Infrastructure

Overview

Components

• Peer/Node -- Maintains connections with the BitCoin network, and relays BitCoin traffic based on policies.
• Wallet -- Maintains private key database, and controls balances for the user.
• UI -- End-user interface. Could be a wx/Qt/GTK GUI, CLI, Android app, iPhone app, etc...
• Miner -- Tries to solve blocks for the wallet.

Protocols

• p2p -- Used for communication between Peers/Nodes, and also between your personal Peer/Node and your Wallet(s)
• wallet -- Used for communication between your Wallet(s) and your Miner(s) and User Interface(s)
