Antiqo: Blockchain-Based Antique Verification and Ownership Management System

This work presents a blockchain-based system for verifying the authenticity and ownership of antiques. The system integrates a web-based frontend, a Node.js backend, MongoDB for data storage, and Solidity smart contracts for immutable ownership tracking. The platform supports user registration with admin approval, antique registration, QR code and serial ID-based verification, and a secure ownership transfer mechanism. Blockchain ensures tamper-proof records and transparency in ownership history. The system improves trust, reduces fraud, and provides a scalable solution for antique verification and provenance tracking.
