Blockchain-Anchored Zero-Knowledge Security Audit Ledger

1. Executive Summary & Architecture Overview

Blockchain-Anchored Zero-Knowledge Security Audit Ledger is an academic project engineered for 4th Year Project students in B.Tech, BCA, B.Sc curricula. The project addresses critical domain challenges by leveraging modern Solidity, Circom, Python, FastAPI to deliver a clean, robust, and reproducible working system ready for college evaluation.

2. Core Technical Objectives

• Develop and deploy a working system using Solidity and Circom.
• Adhere to best software engineering standards tailored for Cybersecurity & Cloud.
• Provide verified source code, comprehensive 10-slide PowerPoint presentation, and IEEE synopsis documentation for defense.

3. Problem Statement & Bottlenecks in Prior Art

• Manual, disconnected procedures causing high latency and human error rates.
• Lack of real-time monitoring, visualization, or validation mechanisms.
• Absence of structured logging, automated reports, and centralized data security.

4. Proposed Architecture & Engineering Advantages

• Automated end-to-end processing pipeline reducing operational turnaround time by over 75%.
• Intuitive responsive interface with live validation and error recovery.
• Complete academic kit customized for B.Tech, BCA, B.Sc final examination.
