I did manage to get through that error by renaming the learncoin.py file to my coin half.py I get the following error now: Traceback (most recent call last): File "/home/crypto/blockchain_fundamentals/bin/sha256", line 4, in from blockchain_fundamentals import * File "/home/crypto/blockchain_fundamentals/bin/blockchain_fundamentals.py", line 8, in coin = os.environ['COIN'] File "/usr/lib/python3.6/os.py", line 669, in getitem raise KeyError(key) from None KeyError: 'COIN'

how to solve. thanks

Hi, sorry you're having trouble, can you show me your folder structure and where your coin file is in relation to the sha256.py file?

Concorde89 commented 4 years ago

No prob. I think it is a folder problem too but don't know how to solve. 1 2 3

Something broke with virtualenv update or something. I have pushed a fix, can you pull the latest, give it a try and let me know? I've updated instructions on the README.

Hey,

to fix the problem you need to type the following into your terminal: $COIN=yourcoinhere $export COIN

Additionally you must have your coin file setup. This can be located in the blockchain/bin folder. You can copy the bitcoin & bitcoin.py files and rename them to your new coin. Alternatively you could use or change the learncoin & learncoin.py files to your new coin.

So long as you've got those two files added AND you've set the COIN variable to be equal to the filename of your coin (and don't forget to export!) then everything should work from there!

Hope that helps! :) Sorry if I made it hard to understand.

Just do this on installation dir (cd blockchain-dev-tools).

//copy both coin files into blockchain-dev-tools folder cp coins/* .

// Execute the file ./msgprefixgen.py

and Voilla !! see the magic.
