This project is a nice reference implementation of a simple cryptocurrency, as such it would be nice to have it with Python 3 support, because it enables more people to test it out. I think a run of 2to3 will suffice, but I will test that out soon.

Hello, i try to run crankycoin, i do python run.py
but i receive this message "Node operation mode not specified", what i need to do?
Hi, found your code searching for example to create my own coin. Interesting code, did you try to publish your coin at index pages like coinmarketcap.com, its still not listed, why?
Hi,
I tried to run the command publickey but I got the below error. Any idea hoe to fix this?
Cranky Coin (CRNK) wallet > publickey
Traceback (most recent call last):
File "run.py", line 218, in

return self.public_key.to_hex()
AttributeError: 'PublicKey' object has no attribute 'to_hex'
This is the first time I'm running this and there is no publickey but I think it should be created now.
Hi!
Thank you for this great project!
I had a confusion with the calculate_hash_difficulty()
function in blockchain.py
. Shouldn't we divide the calculated timestamp_data
by DIFFICULTY_ADJUSTMENT_SPAN
, as we want to adjust the difficulty for just one block?
Issue was caused on a new installation in a new venv
. This was caused because the ./data/
folder did not exist.
We should have a check to see if the directory exists at launch before trying to connect.
Among those two suggestions, perhaps we could consider migrating to sockets rather than HTTP requests? Major performance improvements are possible by doing so, as sockets are far more efficient than HTTP.
