bitcoin-utils-fork-minimal 0.4.11.6

Installation

Python version 3 is required. Then just install with:

$ pip install bitcoin-utils

Examples

Keys and Addresses

https://github.com/karask/python-bitcoin-utils/blob/master/examples/keys_addresses.py - creates a private key which we use to derive a public key and in turn an address. We also use the private key to sign a message and then verify it using the public key.

Segwit Addresses

https://github.com/karask/python-bitcoin-utils/blob/master/examples/keys_segwit_addresses.py - creates P2WPKH, P2SH-P2WPKH, P2WSH and P2SH-P2WSH addresses.

Transaction with P2PKH input and outputs

https://github.com/karask/python-bitcoin-utils/blob/master/examples/p2pkh_transaction.py - creates a simple transaction with one input and two outputs.

Create a P2PKH Transaction with different SIGHASHes

https://github.com/karask/python-bitcoin-utils/blob/master/examples/multi_input_sighash_transaction.py - creates a 2-input 2-output transaction with different signature types.

Create a P2SH Address

https://github.com/karask/python-bitcoin-utils/blob/master/examples/send_to_p2sh_transaction.py - creates a P2SH address that corresponds to a P2PK redeem script and sends some funds to it.

Create (spent) a P2SH Transaction

https://github.com/karask/python-bitcoin-utils/blob/master/examples/spend_p2sh_transaction.py - creates a transaction that spends a P2SH output.

Create a non-standard tx

https://github.com/karask/python-bitcoin-utils/blob/master/examples/create_non_std_tx.py - sends funds to an address with a non-standard tx (script: OP_ADD OP_5 OP_EQUAL)

Spend a non-standard tx

https://github.com/karask/python-bitcoin-utils/blob/master/examples/spend_non_std_tx.py - spends funds from script OP_ADD OP_5 OP_EQUAL

Transaction to pay to a P2WPKH

http://github.com/karask/python-bitcoin-utils/blob/master/examples/send_to_p2wpkh_transaction.py - send coins from two P2PKH UTXOs to a native segwit address (P2WPKH)

Spend from a P2SH(P2WPKH) nested segwit address

http://github.com/karask/python-bitcoin-utils/blob/master/examples/spend_p2sh_p2wpkh_address.py - spend a P2WPKH that is nested into a P2SH for old client compatibility

Create a P2SH address with a relative timelock

https://github.com/karask/python-bitcoin-utils/blob/master/examples/create_p2sh_csv_p2pkh_address.py - creates a P2SH address that locks funds (sent to it) with a private key (P2PKH) and a relative locktime of 200 blocks in the future.

Spend from a timelocked address

https://github.com/karask/python-bitcoin-utils/blob/master/examples/spend_p2sh_csv_p2pkh.py - spends from a P2SH(CSV+P2PKH) address as created from above.

Use NodeProxy to make calls to a Bitcoin node

https://github.com/karask/python-bitcoin-utils/blob/master/examples/node_proxy.py - make Bitcoin command-line interface calls programmatically (NodeProxy wraps jsonrpc-requests library)

Please explore the codebase or the API documentation (BitcoinUtilities.pdf) for supported functionality and other options.
