WikiChain: A Blockchain-Based Decentralized Wiki Framework

Wiki-based application, such as Wikipedia, uses collective intelligence to build encyclopedias collaboratively. Most wiki-based applications currently adopt centralized system architectures. Although some work has studied the problem that centralized architectures are unreliable, existing implementations still face some challenges, such as non-disclosure, non-transparency and insecurity. Recently, blockchain has gained extensive attention due to its irreversibility, consensus mechanism and decentralization. We propose a novel blockchain-based wiki framework named WikiChain, which provides decentralized, fair, efficient and collaborative knowledge management. Additionally, we present the workflow of WikiChain by smart contracts and adopt IPFS to store large-scale data. Finally, we implement a prototype on Ethereum and evaluate the efficiency of WikiChain. The experimental results show the utility and scalability of WikiChain.
