Decentralized Social Media Platforms: Enhancing Privacy, Security and User Control Using Blockchain Technology

Abstract

In the current digital era, social media platforms have become pivotal for individuals to express their opinions, political views, and product reviews. However, the centralized nature of traditional social media systems poses significant risks related to data breaches, server crashes, and single points of failure. To address these challenges, this paper proposes a novel approach to migrate from centralized to decentralized social media platforms by leveraging Blockchain technology. Blockchain ensures data immutability, decentralized storage, and enhanced security by distributing data across multiple nodes. Any tampering with data is immediately detectable due to the cryptographic linkage of data blocks through unique SHA-256 hash codes. The proposed system, named dTweets, enables users to post and view tweets securely using smart contracts written in Solidity and deployed on the Ethereum network. This decentralization prevents fraudulent users from spreading misinformation or unauthorized advertisements. Experimental results demonstrate that the proposed system achieves strong data integrity, tamper resistance, and transparent operation while maintaining acceptable transaction latency. This implementation provides a robust foundation for a secure and tamper-proof social media ecosystem.
