This project is a COBOL-based payroll application that integrates with a Python-implemented blockchain. The purpose of this integration is to provide an immutable record of payroll transactions, ensuring easier auditing and compliance with financial regulations.

• Payroll processing using COBOL
• Immutable transaction records using a Python blockchain
• Consensus algorithm for resolving conflicts in the blockchain network
• Easy node registration for blockchain network expansion

• blockchain.py: The main blockchain implementation in Python.
• transaction.py: Defines the structure and behavior of a transaction.
• block.py: Defines the structure and behavior of a block.
• chain_utils.py: Utility functions for the blockchain, such as hashing and validation.
• blockchain_config.json: Configuration settings for the blockchain.
• payroll.cbl: The COBOL program for processing payroll.
• employee_record.cpy: The COBOL copybook for employee records.
• payroll_record.cpy: The COBOL copybook for payroll records.
• payroll_config.cpy: The COBOL copybook for payroll configuration.
• integration.cbl: The COBOL program for integrating with the Python blockchain.
• blockchain_interface.py: The Python interface for interacting with the COBOL application.
• requirements.txt: The Python dependencies required for the blockchain.
• README.md: This file, describing the project and how to use it.
• Makefile: A makefile to automate compilation and other tasks.

• Python 3.x
• COBOL compiler (e.g., GnuCOBOL)
• Python libraries as listed in requirements.txt

1. Install the required Python libraries:

pip install -r requirements.txt

2. Compile the COBOL programs:

make compile

1. Start the blockchain node:

python blockchain.py

2. Run the COBOL payroll application:

cobcrun payroll
