Research on blockchain in social networking has gained momentum as decentralized platforms emerge to address issues inherent in traditional social media, such as data privacy, content moderation, and user autonomy. Studies have proposed frameworks that integrate blockchain technology to enhance security and trustworthiness in online social interactions. For instance, a blockchain-enhanced framework for social networking aims to secure online platforms by leveraging blockchain immutable ledger and smart contracts. Additionally, a systematic literature review examines the application of blockchain technology in social media, highlighting its potential to address challenges like misinformation, lack of effective content moderation, and data breaches. Furthermore, the development of decentralized online social networks (BCOSN) demonstrates how blockchain can facilitate user control over data and content, promoting a more user-centric approach to social networking. These research efforts underscore the transformative potential of blockchain in reshaping the landscape of social media towards greater transparency, security, and user empowerment.
