JaamoCoin - simple Python blockchain example

This is a very simple blockchain example written in Python.

Based on this tutorial: https://medium.com/coinmonks/python-tutorial-build-a-blockchain-713c706f6531

I modified the code to support proof of work calculation.

You can test this in Python console:

python3 -i jaamocoin.py

And then you can start playing around:

jcn.new_transaction("thebank", "jaamo", 5)
jcn.new_transaction("jaamo", "valo", 1)
jcn.new_transaction("jaamo", "mattiteppo", 1)

You can debug what's going on in the chain anytime:

jcn.print()

And you can always check the current balance of an user by calling:

jcn.get_balance("jaamo")

If you want to run test script:

python3 test.py
