Blockchain Integration in CBBPM: Design and Implementation for Enhanced Security and Efficiency

The provided PHP snippets illustrate various server-side functionalities. They encompass transaction processing, file management, hash handling, and interfacing with a supernode for blockchain network connectivity. The sections include: 1. PHP Code for Processing POST Requests: Designed to receive transaction data from users, validate inputs, store information in text files, and display error messages to users. 2. PHP Code for Displaying Address Balances: Developed to search and display balances and transactions associated with each address on the blockchain network, including reading text files and presenting information in a table format. 3. PHP Code for File and Hash Management on the Supernode: Intended for file management, hash generation, relocation, and deletion within various directories. Functions such as scandir, file_get_contents, file_put_contents, rename, and unlink are employed for these operations. These code snippets demonstrate the utilization of PHP to implement different components of a transaction and file management system for a blockchain-based application, encompassing security, data validation, and communication with a supernode for data exchange.
