摘　　要：The 5G mobile Internet facilitates contents generation for online communities and platforms through human-to-human collaboration.Wikipedia,a well-known online community,uses wiki technology to build an encyclopedia through collective intelligence and collaboration.Mainstream wiki systems adopt a centralized implementation,and while existing studies have optimized the efficiency of the wiki systems'centralized implementation,these systems still suffer from a lot of problems,for example,opacity and distrust.Over the years,blockchain has brought a flurry of fervour and decentralization to the system architecture,meanwhile giving users a sense of trust and participation.Thus,an innovative blockchain-enabled wiki framework called DecWiki is proposed to build one transparent,truthful,collaborative and autonomous encyclopedia.After several participatory design iterations,we present DecWiki's detailed architecture and its implementation in the form of a smart contract and use the interplanetary file system to complement the big data storage.Meanwhile,we use the trusted execution environment to secure sensitive information in the wireless scenario.Finally,the system overhead and the acceptance of the prototype are evaluated.Extensive experiments present its significant performance.
