Run the Project using "python3 app.py"

The project runs on:- localhost/http://127.0.0.1:5000

Explanation:- This Flask web application manages a to-do list using blockchain technology. It defines two classes: Block, which represents a single task in the blockchain, and Blockchain, which manages a chain of tasks.

Block Class: Represents each to-do item with attributes like index, previous_hash, timestamp, task, hash, and completed status. Blockchain Class: Manages the list of tasks with methods to add tasks, mark tasks as completed, remove tasks, and validate the chain's integrity. It starts with a "Genesis Block" and uses SHA-256 hashing to ensure data security. The Flask app provides endpoints to:

Add a new task (/add_task). Mark a task as completed (/complete_task). Remove a task (/remove_task). Retrieve the entire blockchain (/get_chain). View the blockchain through a web page (/view_chain). The app runs in debug mode, allowing users to interact with the to-do list through a web interface and manage tasks using the blockchain.

Summary:- Component Function:- Block Class Defines the structure of a single to-do task with properties and a hash. Blockchain Class Manages the list of tasks with methods for adding, completing, and removing tasks. /add_task Adds a new task to the blockchain. /complete_task Marks a specific task as completed. /remove_task Removes a task from the blockchain. /get_chain Retrieves the full list of tasks as a JSON object. /view_chain Displays the blockchain through a web page.

The output is viewed as a simple HTML page in the browser.
