Bitcoin Scripting Assignment

This project demonstrates how to interact with Bitcoin Core using RPC to create, analyze, and broadcast transactions between legacy (P2PKH) addresses. The scripts cover the complete workflow of creating transactions, examining their structure, and understanding Bitcoin's locking and unlocking mechanisms.

Prerequisites

• Bitcoin Core installed and configured
• Python 3.6+
• python-bitcoinrpc library

Setup

1. Start Bitcoin Core in Regtest Mode

Regtest mode allows you to create a local Bitcoin blockchain for testing:

 bitcoind -regtest -daemon -fallbackfee=0.0002

2. Create a Wallet

Create a new wallet or use an existing one:

bitcoin-cli -regtest createwallet "mywallet"

If already created wallet or use an existing one:

bitcoin-cli -regtest loadwallet "mywallet"

3. Configure RPC Credentials

Ensure your RPC credentials are set in the ~/.bitcoin/bitcoin.conf file.
Set

  BITCOIN_CLI = "/home/yash-singh/bitcoin-25.0/bin/bitcoin-cli"

in both python programs (prg1.py and prg2.py)

Usage

Run the Python scripts to interact with Bitcoin Core:

python prg1.py
python prg2.py
