Tutorial: creating a bitcoin instawallet clone with python and django

[EskimoBob]

I just had an idea. Make an instawallet with a "Double or Nothing" button. Just a huge irresistible button that either doubles your balance or takes it all. Take a 1% or whatever fee by giving only 49.5% odds. Have to publish the max amount you can handle covering, maybe make it dynamic. If someone actually wants to do this I could probably put up some cash.

You really need to see a specialist about your gambling addiction.

In more serious note.
Feature request #1 : Additional module for tipping aka "Bitcoin me" URI
Generate a special URL, that can me used for only receiving a tip. I personally like the "Bitcoin me" URI idea:

Code:

<a href="bitcoin:'bitcoin address here'?amount='amount here'&label='label here' ">bitcoin me!</a>

 
(remove the " ' ")

This starts your bitcoin client and you can complete the payment.
Obviously, this can be redesigned/reversed so that your web based wallet is opened, authentication is requested and payment is made.
Something like "Tip me from 'service name' "

Code:

<a href="https://:wallet_serviceURL?amount='amount here'&label='Tip for the article' ">Bitcoin tip!</a>

Feature request #2:
To add another layer of security, wallet service user must select/upload a "security image" for his/her account.
This image is always displayed when he logs in to his account or starts to complete the tip payment. If someone has lured a user to a fake phishing site, image is missing or is not correct. User with a half a brain must notice this and stop. This actually requires a FR #3

Feature Request #3 Transactions or any changes to users account can not be completed without "PIN". PIN number is generated to user when account is first created.

Lol, I want to own it not to use it. Does that mean I'm in the clear or is that just worse?

Well, creating a gambling site with django_bitcoin is trivial. It could be of course an anonymous gambling site as well - just deposit your bitcoins to this address, and then you have gambling functionalities there.

eg. "double or nothing" pseudocode:

Code:

import random
from django_bitcoin import Wallet

def double_or_nothing(request, uuid):
    main_wallet=Wallet.objects.get(id=1) # the main wallet, where the site's bitcoins are kept
    user_wallet=Wallet.objects.get(uuid=uuid)
    if random.random()<0.49:
         main_wallet.send_to_wallet(user_wallet, user_wallet.total_balance())
    else:
         user_wallet.send_to_wallet(main_wallet, user_wallet.total_balance())

I just wrote the code directly here, so perhaps it doesn't work But anyway, the basic idea is very simple. Then of course, if you want to implement more complex gambling functionalities, it is easy.

I'm not implementing this, since I think it doesn't fit well with wallet... But the library itself could be used as well for gambling sites, or almost anything.

Code:

ImportError at /

Any idea why do I get "No module named instawallet.urls"

In settings.py change ROOT_URLCONF from 'instawallet.urls' to just 'urls'

I'm stuck with getting the QR code to display.

At the moment the image location is showing as http://10.1.1.14:8000/qrcode/mnooEeJ3GjR8ztUby9Ch9vgrp9BE6at6HV

I guess it needs to lookup the QR code through Google somehow but I have no idea.

Any ideas?

I have a question about the directory structure of django-bitcoin-instawallet and django_bitcoin.

I have django_bitcoin installed in the project folder, instawallet and the app wallets inside instawallet.

leo@ubuntu:~/django/instawallet/instawallet$ ls
dev.db             __init__.pyc   settings.pyc   urls.pyc   wsgi.pyc
django_bitcoin  manage.py     templates      wallets
__init__.py      settings.py     urls.py          wsgi.py

My question is can {% load currency_conversions %} from ~/django/instawallet/instawallet/templates/instawallet.html reach ~/django/instawallet/instawallet/django_bitcoin/templatetags/currency_conversions.py given the ~/django/instawallet/instawallet/settings.py file has 'django_bitcoin', in the INSTALLED_APPS?

Today at Bitcoin Hackathon, I started a new project, and fixed some problems with django_bitcoin that only affect new users. These problems were mostly when you used easy_install or pip. I myself have always used cloned repository, so it didn't affect me.

Thanks for your suggestion, I will try again from clean install.

About the qrcode-library, can you please point me in the right direction for this dependancy?

All the requirements are in requirements.txt, you can install them using

pip install -r requirements.txt

or

pip install qrcode
