A Blockchain-Powered Complaint Ledger System

🚀 Overview

Shikayat Block is an innovative, blockchain-based complaint ledger system designed to bring transparency, security, and efficiency to the process of handling complaints. Built on the Ethereum blockchain, it leverages smart contracts to store complaint records immutably, ensuring they cannot be altered or tampered with. By integrating encryption, real-time updates, and AI-powered classification, Shikayat Block revolutionizes the way grievances are managed and resolved.

The system allows users to register complaints securely while enabling administrators and concerned authorities to track, manage, and resolve them efficiently. A key advantage is the automatic categorization and priority assignment of complaints through machine learning, ensuring that critical issues are addressed promptly. With multilingual support, the platform is accessible to a broad user base, making it particularly useful in regions where linguistic diversity is a factor.

Whether for governmental agencies, corporate grievance redressal, or community-based issue tracking, Shikayat Block offers a scalable, robust, and user-friendly solution for complaint management.
