A LAYERED BLOCKCHAIN-BASED SECURE MESSAGING ARCHITECTURE WITH SMART CONTRACT-DRIVEN CERTIFICATE MANAGEMENT SYSTEM

Abstract

 In the contemporary digital landscape, the demand for secure, private, and tamper-resistant communication has never been more critical. Conventional messaging platforms, which predominantly rely on centralized servers, are increasingly vulnerable to data breaches, unauthorized surveillance, and censorship. Even with the adoption of end-to-end encryption, these systems remain susceptible to single points of failure and metadata exposure, undermining user privacy and trust. Blockchain technology has emerged as a transformative solution to these challenges, offering a decentralized, immutable, and transparent infrastructure for secure data exchange. By leveraging distributed ledger technology, Blockchain-based messaging systems eliminate the need for trusted intermediaries, enhance resistance to censorship, and ensure data integrity through consensus-driven validation.
