🔥Litcoin

A library for interacting with Bitcoin and Litecoin (and possibly more similar cryptocurrencies in the future)

Tenets

  • Abstract all the commonalities of these cryptocurrencies and parameterize functions with the name of the network in question.
  • Use simple data structures such as bytes, str, list and dict instead of class.
  • Be easy to translate into other languages.
  • Have as few dependencies as possible.
  • Be a central point of failure, but don't fail.
  • Be functional.
  • Abstract all 3rd party code
  • Test everything.

Build / Install

To develop or experiment with litcoin, we recommend using virtual environments.

Create and initalize a virtual environment:

virtualenv -p python3 venv
. venv/bin/activate

Install pytest:

pip3 install pytest

Build:

./setup.py build

Run Tests:

pytest

Install:

pip install .

Usage

Creating keys and addresses

>>> from litcoin.address import make_p2pkh_address
>>> from litcoin.ec import make_privkey, derive_pubkey
>>> privkey = make_privkey()
>>> privkey
b'\xc5\xaeYw\xf5\x9e\xa9-\x9a\x11\x88Vd5\xccg/<\xae\xa6e\xbf\x85\xa2\xfb\x92=\xe8:\xe0$\x0e'
>>> pubkey = derive_pubkey(privkey)
>>> laddr = make_p2pkh_address(pubkey, network='litecoin')
>>> baddr = make_p2pkh_address(pubkey, network='bitcoin')
>>> laddr
'LL8SyH86F6SeKZPDBWDYpFcQg4v775yG9v'
>>> baddr
'1uVi4pGASCb4kh41NEFYEYeTrYpyhfULL'
