zblockchain

Zed's blockchain, inspired by jackschultz/jbc.

Wanted to do a few things differently:

1. Python 3 (written on 3.6.3)
2. No dependencies - standard libs only.
3. No linking directories.

Running a Node

python main.py

Options:

• -g create the genesis block.
• -m mine, if not given node will just listen.
• -p PORT port number to use (between 3000-3007). Uses 3000 if not given.

Blocks are stored under /chain/<PORT>.

Example Usage

From a fresh clone, in one terminal do:

python main.py -g -m

This starts the first node on 3000, creates the genesis block, and starts mining.

In a second terminal do:

python main.py -p 3001

This starts another node on 3001 that syncs up the longest chain then just listens for broadcast blocks.

In a third terminal do:

python main.py -p 3002 -m

This starts another node on 3002 that syncs up the longest chain then competes for mining blocks.

Etc..
