MinimalisticBitcon

Minimalistic Bitcoin is a very small implementation of Bitcoin.

I wrote it to have a better understanding of the Bitcoin protocol at low-level

Quick Start

• Clone the repository. git clone https://github.com/hg333/MinimalisticBitcon.git
• Execute connection.py file python3 connection.py

That's it, you have a very tiny, very limited bitcoin-node working at port 8333 of your machine.

P2P-Network

The network between two nodes is estavlished via handshake demonstrated above.

Configurations

Version

Default version is set to 70002, can be changed by editing the respective variable in connection.py

version = struct.pack("i", 70002)

Host

By defalt the application tries connecting to the node at address 24.64.72.174:8333.

HOST = "24.64.72.174"
PORT = 8333

For connecting to other nodes find a stable node at bitnodes
