基于区块链的在线社区知识共享方案研究

Research on Online Community Knowledge Sharing Scheme Based on Blockchain

随着互联网络的快速发展,虚拟社区不断涌现.这些社区在提供创新资源的同时,也存在着诸如用户分享意愿不高、社区缺乏良好激励机制等问题,区块链能够很好地解决这些问题,促进社区的知识共享.本文构建了基于跨链的在线社区知识共享方案,提出了“元数据+云存储”的资源访问与存储模式,详细设计了元数据信息表,设计了知识共享方案的总体框架及部分业务的关键流程,提出了采取“提名权益证明(NPOS)”的共识机制来设计区块链网络,实现了在线社区知识共享的部分功能.经分析与实验,本文的方案具有良好的科学合理性、安全性和执行效率,对其他相关项目的开展具有重要的参考价值.

With the rapid development of the Internet,virtual communities are constantly emerging.While these communities provide innovative resources,there are also problems such as the low willingness of users to share and a lack of good incentive mechanisms.Blockchain can better solve these problems and promote community knowledge sharing.This paper constructs an online community knowledge sharing scheme based on Multi Chain,proposes the resource access and storage mode of“metadata&cloud storage”,designs the metadata information table in detail,and designs the overall framework of the knowledge sharing scheme and the key processes of some businesses.Based on the key process,the consensus mechanism of“Nominated Proof of Stake(NPOS)”is proposed to design the blockchain network,which realizes some functions of online community knowledge sharing.Through analysis and experiment,the scheme of this paper has good scientific rationality,safety and execution efficiency,and has good reference value for the development of other related projects.
