Bitcoin Public Key/Address Extractor

This Python script connects to a locally running Bitcoin (or compatible) node, scans a specified range of blocks, and extracts public keys found within transactions along with their corresponding P2PKH addresses.

Features

• Node Connection: Connects to a local Bitcoin node via JSON-RPC.
• Block Scanning: Scans blocks within a specified height range.
• Data Extraction: Extracts public keys from transactions (found in scriptSig and P2PK outputs).
• Address Conversion: Converts the extracted public keys into their corresponding P2PKH (Pay-to-Public-Key-Hash) Bitcoin addresses.
• Result Saving: Saves the unique PublicKey: Address pairs to a specified output file.
• Error Handling: Includes basic RPC connection retry logic and prompts the user for manual reconnection attempts after repeated failures.

Prerequisites

1. Python 3: Python 3.x must be installed.
2. Running Node: A locally running Bitcoin Core node (or a compatible one) with RPC service enabled.
3. RPC Credentials: The RPC username and password for your node.

Configuration

Before running the script, you need to modify the following constants at the beginning of the script to match your node's configuration:

# RPC Connection Settings
RPC_USER = 'Your_RPC_Username'     # Change to your RPC username
RPC_PASSWORD = 'Your_RPC_Password' # Change to your RPC password
RPC_PORT = '8332'                  # Change if your node uses a different port
RPC_URL = f'http://127.0.0.1:{RPC_PORT}' # Usually no need to change unless the node is not local

Note: Hard-coding the RPC password directly into the script will bring certain security risks. Please test it with an empty wallet with no balance. Ensure the script file has appropriate access permissions.

Install Dependencies

This script requires the requests and base58 libraries. You can install them using pip:

pip install requests base58

Alternatively, save the following as a requirements.txt file:

requests
base58

Txt Then run:

pip install -r requirements.txt

How to Run

Run the script using the following command format:

python3 extract_data.py <start_block_height> <end_block_height> <output_filename>

Parameters:

<start_block_height>: The block height (integer) where you want to start scanning.

<end_block_height>: The block height (integer) where you want to end scanning (inclusive).

<output_filename>: The name of the text file to save the extracted results (e.g., output_pairs.txt).

Example:

Scan blocks from 100000 to 100100 (inclusive) and save the results to output_pairs.txt:

python3 extract_data.py 100000 100100 output_pairs.txt

If the script loses connection to the node during execution, it will attempt to reconnect a few times. If it still fails, it will prompt you to press 'P' to manually trigger a reconnection attempt.

Output File Format

The output file will contain multiple lines, each with the following format:

:
