nang-dev / customcryptocurrency Goto Github PK

Don't want to be that guy but... CustomCryptocurrency is spelled wrong. You missed a 't' there. Anyways just wanted to point that out

I always get this error while signing up :-(

Hey there!

So running this on the same system is easy but how do I run & sync this over multiple systems? I have the website up n running and accessible via a domain but cant seem to figure out how anyone would "become a node"

Hi! I ran run.py and run2.py but those nodes have different blockchains

No No module named 'Crypto' could use some help

Hey, can anyone please clarify in helping fix this while registering for a new account

Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Got port 80 running after running python3 run.py (using python 3.7) and installing all dependencies. On Register after clicking sign-up I get "Internal Server Error. The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."

In terminal:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/sqlalchemy/util/_collections.py", line 1008, in call
return self.registry[key]

AttributeError: can't set attribute

all dependencies are pip installed for python3.

Wondering how I can fix this issue for sign-up!

I was looking through the blockchain.py file and noticed that the isValidTransaction() function which should verify the validity of the transaction doesn't actually check that signature so anybody can forge transactions on someones behalf using a fraudulent private key.

Gives 500 Internal Server Error.

In run.py terminal, it gives this error:

Help would be appreciated.

When i post this on a web server and try to sign in it gives me an error 500

Don't want to be that guy but... CustomCryptocurrency is spelled wrong. You missed a 't' there. Anyways just wanted to point that out

uhh hello how do i change all of the gymcoin text including the website name and the others

i get this error everytime i try to sign up

I have created the requirement file with the content below

requests==2.26.0
Flask==2.0.1
flask_bcrypt==0.7.1
flask_login==0.5.0
flask_sqlalchemy==2.5.1
flask_wtf==0.15.1
jsonpickle==2.0.0
pycryptodome==3.10.1
WTForms==2.3.3

Then ran the command like

pip install -r gymcoin/requirements.txt

Now the dependencies are restored

Whenever i run > python run.py or python run2.py nothing happens
I have checked the Url also
http://127.0.0.1:5001/

It (the debugging) stops at " from gymcoin.blockchain import * ". ImportError: No module named gymcoin.blockchain!
Btw my friend chose the name
