Research And Application Of Digital Content Distribution Platform Based On Blockchain Smart Contract

Digital content distribution includes processes such as content sharing,publishing,and promotion.In the traditional digital content distribution process,the distribution of benefits is mostly determined by the content platform,but the various content data of the platform are not open and transparent,the rights of users are unevenly distributed and lack of protection,and the copyright protection of digital content is inadequate implementation,making it hard for good content to get its true value,and thus the credibility of the platform is reduced,make the development of the whole industry is restricted.In an environment where the good digital content and bad ones are intermingled while the user incentive mechanisms are not perfect,the emergence of blockchain technology has brought the possibility of innovation in digital content distribution.Blockchain technology combines the fields of computer science and cryptography,replaces intermediaries with smart contracts so the platform no need to transfer rights.With the development of blockchain technology,decentralized application development can be based on the underlying structure of the blockchain to solve the dilemma of content distribution.According to the above background,this paper realizes a decentralized application platform covering the whole process of digital content distribution.The platform is equipped with a digital content distribution system,based on the actual demand,designed and developed many functions under user management module,digital content management module,incentive settlement module and blockchain information module by using smart contract,with the interface of ethereum Web3.js to build an interactive bridge between the front-end interface and smart contract.In addition,the platform also embeds a user incentive mechanism,based on the calculation rules,the real evaluation results of digital content distribution are used as the basis for reward distribution,so as to protect the reasonable rights and interests of users.By building a development environment,configuring a node cluster,and deploying a blockchain network,the platform can run normally in the blockchain environment.Finally,testing the functions of digital content distribution platform.The test results verify the usability and stability of platform,allowing the target audience to obtain content information,and can solve the black-box operation phenomenon that exists in the process of digital content value exchange and transfer.By designing a reasonable incentive mechanism,changed use work flow as the sole criterion for evaluating content quality,helps to safeguard the interests of the originator.
