WikiChain: An Improved Resilient, Pseudo-Transparent Knowledge Base

Abstract

The traditional centralized knowledge base paradigm, exemplified by platforms like Wikipedia, grapples with numerous challenges like a solitary point of collapse, issues related to transparency, and potential integrity concerns in articles. To address these shortcomings, an innovative blockchain-enabled alternative is proposed which leverages the inherent features of transparency and decentralization offered by blockchain technology. This system ensures a secure and tamper-proof recording of articles by capitalizing on the unique attributes of blockchain. However, the integration of blockchain alone does not completely eradicate challenges, as instances of vandalism persist, and a robust validation process for articles within the system is lacking. To overcome these issues, our research aims to proactively prevent the inclusion of falsified articles by implementing a consortium blockchain by utilizing Contenders Selection (CS) and Dynamic Consortium Membership Determination (DCMD) algorithms. Furthermore, we address the challenge of missing articles from the InterPlanetary File System (IPFS) using Proof-of-Existence (POE) algorithm. This holistic solution is designed to significantly enhance the efficiency of the system and elevate the overall quality of articles. Our research presents promising results, with the percentage of approved articles compared to proposed articles falling within the range of 10% to 15%. Consequently, the data volume of the blockchain network in our system is 66.7% more effective than the existing decentralized Wikipedia model. Notably, the average block time of our proposed system exhibits a commendable 21% improvement compared to the existing system, emphasizing the potential for increased efficiency and reliability in our blockchain-enabled knowledge base.
