bitsv 0.5.3

Bitcoin SV made easier.

BitSV: Bitcoin SV made easy.
=======================

NOTE about cashaddresses
========================

Bitcoin SV will be slowly reinstating legacy address format as the default standard. Cashaddress is a great tool for conversions if need be. https://github.com/oskyk/cashaddress/

Forked from Ofek's awesome Bit library: https://github.com/ofek/bit

Try to ignore the out of date bits on the README which refer to Bitcoin Cash and not Bitcoin SV.

What needs fixing
----------------

- This README.
- The test cases...
- Testnet
- Networking for broadcasting 100 kilobyte OP_RETURNS to miners
- Rates (so 'usd', 'jpy', etc work as they do in bit)

**BitSV is so easy to use, in fact, you can do this:**

.. code-block:: python

>>> import bitsv
>>>
>>> my_key = PrivateKey('YourPrivateKeyGoesHere')
>>> my_key.get_balance('usd')
'12.51'
>>>
>>> # Let's donate!
>>> outputs = [
>>> # Wikileaks
>>> ('1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v', 0.0035, 'bch'),
>>> # Internet Archive
>>> ('1Archive1n2C579dMsAu3iC6tWzuQJz8dN', 190, 'jpy'),
>>> # The Pirate Bay
>>> ('129TQVAroeehD9fZpzK51NdZGQT4TqifbG', 3, 'eur'),
>>> # xkcd
>>> ('14Tr4HaKkKuC1Lmpr2YMAuYVZRWqAdRTcr', 2.5, 'cad')
>>> ]
>>>
>>> my_key.send(outputs)
'9f59f5c6757ec46fdc7440acbeb3920e614c8d1d247ac174eb6781b832710c1c'

Here is the transaction `<https://blockchain.info/tx/9f59f5c6757ec46fdc7440acbeb3920e614c8d1d247ac174eb6781b832710c1c>`_.
