Elements module for python-bitcointx
Project description
This Python3 module implements support for Elements transactions.
It builds on top, and is intended to be used along with python-bitcointx library.
Requirements
-
python-bitcointx (version >= 1.0.0)
-
Configure parameters for
secp256k1-zkp
:
./configure --enable-experimental \
--enable-module-generator \
--enable-module-rangeproof \
--enable-module-surjectionproof \
--enable-module-ecdh \
--enable-module-recovery
Usage:
With contextual switch to Elements parameters:
import os import elementstx from bitcointx import ChainParams, get_current_chain_params from bitcointx.wallet import CCoinKey, CCoinExtKey, CCoinAddress, P2PKHCoinAddress with ChainParams('elements'): k = CCoinExtKey.from_seed(os.urandom(32)) a = P2PKHCoinAddress.from_pubkey(k.derive_path("m/0'/0'/1").pub) print('example {} address: {}'.format(get_current_chain_params().name, a)) assert CCoinAddress(str(a)) == a
With global switch to Elements parameters:
from elementstx import ElementsParams from bitcointx import select_chain_params select_chain_params('elements') # or, using the chain params class directly select_chain_params(ElementsParams)
Without the switch of chain parameters:
from elementstx.core import ElementsTransaction transaction_data = read_tx_data() tx = CElementsTransaction.deserialze(transaction_data) print("Number of txout witnesses:", len(tx.wit.vtxoutwit))
