Distributed Mining System (UDP + Load Balancer)

This project implements a scalable and secure distributed mining system using the UDP protocol, later extended with a Load Balancer architecture.

Project Structure

Part 1 – Basic UDP Mining System

File	Description
Block_Part1_22_5.java	Data model representing a mining block (number, nonce, data, and hash).
Client_Part1_22_5.java	UDP client that sends mining requests to the server.
Server_Part1_22_5.java	UDP server that performs mining by finding a suitable nonce.
StringUtil_Part1_22_5.java	Utility for hashing and checking hash difficulty (number of leading zeros).

Part 2 – Load-Balanced UDP Mining System

File	Description
Block_Part2_22_5.java	Extended block model compatible with the load-balanced system.
Client_Part2_22_5.java	Client that sends mining jobs through the Load Balancer.
LoadBalancer_Part2_22_5.java	Distributes mining ranges to multiple servers.
Server_Part2_22_5.java	Performs mining on assigned nonce ranges.
StringUtil_Part2_22_5.java	Utility reused for consistent hash validation.

Features

• Simple and lightweight UDP-based client-server architecture.
• Mining simulation by finding nonce values for hashes with specified leading zeros.
• Load balancing via a custom module that divides mining ranges among multiple servers.
• Performance analysis of execution time across clients and difficulty levels.

Performance Analysis

The system has been tested with multiple clients, variable difficulty (leading zeros), and different numbers of servers. Results showed significant improvements with load balancing.

How to Run

1. Compile all Java files.
2. Run the server(s) and load balancer in appropriate order.
3. Run multiple clients to simulate mining requests.
4. Monitor the console for execution time and mining results.
