摘要
随着互联网和移动终端的普及,数字内容产业正成为文化产业主要经济增长点.本文从数字内容产业面临的版权、质量和产业壁垒问题入手,分析区块链技术对于建设数字内容生态价值链的意义和优势,提出以基于区块链的数字内容平台重塑生态价值链的方案.然后分析新型平台中的关键元素、价值流转、平台架构,设计平台价值流转过程中的基础方案,最后从成本和性能角度证明联盟链适合并且可以支撑平台构建.
With the popularity of the Internet and mobile terminals,the digital content industry is becoming the main economic growth point of the cultural industry.Starting from the copyright issues,quality issues and industry barriers faced by the digital content industry,this paper analyzes the advantages and significance of the blockchain technology in the construction of the digital content.Then reinventing the digital ecological value chain through a blockchain-based digital content platform is proposed,and the key elements,the value transfer method and the system architecture of the new platform are analyzed.Then the basic program design of the value transfer process of the platform is given.Finally,experimental analysis proves that the consortium blockchain is suitable and can support the construction of the platform from the perspective of cost and performance.
