Python Bitcoin Library

Bitcoin cryptocurrency Library writen in Python.

Allows you to create a fully functional Bitcoin wallet with a single line of code. Use this library to create and manage transactions, addresses/keys, wallets, mnemonic password phrases and blocks with simple and straightforward Python code.

You can use this library at a high level and create and manage wallets from the command line or at a low level and create your own custom made transactions, scripts, keys or wallets.

The BitcoinLib connects to various service providers automatically to update wallets, transaction and blockchain information.

Install

Installed required packages

$ sudo apt install build-essential python3-dev libgmp3-dev

Then install using pip

$ pip install bitcoinlib

For more detailed installation instructions, how to install on other systems or troubleshooting please read https://bitcoinlib.readthedocs.io/en/latest/source/_static/manuals.install.html

If you are using docker you can check some Dockerfiles to create images in the docker directory.

Example

The bitcoin library contains a wallet implementation using SQLAlchemy and SQLite3 to import, create and manage keys in a Hierarchical Deterministic way.

Example: Create wallet and generate new address (key) to receive bitcoins

>>> from bitcoinlib.wallets import Wallet
>>> w = Wallet.create('Wallet1')
>>> w.get_key().address
'1Fo7STj6LdRhUuD1AiEsHpH65pXzraGJ9j'

Now send a small transaction to your wallet and use the scan() method to update transactions and UTXO's

>>> w.scan()
>>> w.info()  # Shows wallet information, keys, transactions and UTXO's

When your wallet received a payment and has unspent transaction outputs, you can send bitcoins easily. If successful a transaction ID is returned

>>> t = w.send_to('1PWXhWvUH3bcDWn6Fdq3xhMRPfxRXTjAi1', '0.001 BTC', offline=False)
'b7feea5e7c79d4f6f343b5ca28fa2a1fcacfe9a2b7f44f3d2fd8d6c2d82c4078'
>>> t.info  # Shows transaction information and send results
