Sociala: An Incentivized Decentralized Social Media for writers based on Blockchain using modified Delegated Proof of Stake

Abstract

Over the past few years, there has been a profound evolution in decentralization methodologies, owing largely to the emergence of novel decentralized technologies like blockchain. In the realm of online social media, a paradigm shift has been suggested with the introduction of blockchain-based online social media (BOSM), heralding a potential future for social media platforms wherein users are duly rewarded for their valuable contributions. Despite the widespread adoption of these platforms by millions of users, it is crucial to acknowledge that their decentralization remains incomplete. One prevailing issue within existing blockchain systems resides in the vulnerability of the Delegated Proof of Stake (DPoS) consensus algorithm, which is susceptible to manipulation by the few selected nodes. Anticipating the demands of the forthcoming generation of social media, the pivotal imperative lies in establishing decentralization as its foundational hallmark. In this paper, we present Sociala, an incentivized blockchain-based framework tailored for writers. To effectively address the pitfalls of centralization and minimize the likelihood of nefarious node selection, we proffer an enhanced multi-step DPoS consensus algorithm, which is referred as modified DPoS (mDPoS). This advanced algorithm embraces both the tenets of randomness and diversity, coupled with the inclusion of input from general users, culminating in fortified system stability.
