Secure Real-Time File Sharing Using Blockchain Technology

In the modern digital age, secure and efficient file sharing is paramount. This paper presents a
blockchain-based real-time file sharing application that ensures data integrity, confidentiality, and decentralized
access. The system is developed using Python and JavaScript, with Flask as the backend framework and AES
encryption for data security. Users can sign up, upload files, share them via links, and download them, all while
transactions are logged immutably on a blockchain. This application offers a reliable, transparent, and tamper-
proof solution for personal and organizational data exchange
