The Research And Design Of Blockchain Support Platform For The Internet Of Things Applications

In the past two years,blockchain technology has been explored in new directions of development.With the explosive growth of Internet of things devices,the traditional technical scheme and system structure are probabily unable to adapt to the development of Internet technology in the future.Centralized structural architecture will bring enormous pressure and challenges to the production operators on hundreds of billions of Internet equipment tube issues.And also,massive Internet equipment data can't get better utilization and safety protection in traditional centralized management.The blockchain has three characteristics:decentralization,trustworthiness,high security and high privacy,which provides a solution to directly data transmission for Internet of things.Considering the current hot research spots in blockchain technology and according to the characteristics of the application in the Internet of things,this paper focuses on analysis of the existing various core consensus algorithms of block chain and comparison experiments.It chose the most suitable consensus algorithm as the improved strategy for application in the Internet of things platform,and realized an efficient blockchain system combining with currently the most popular Ethereum blockchain platform.This paper designed a new Internet blockchain platform architecture,where the users and the Internet of things devices are taken as peers in the blockchain,thus provided the ability of point to point interaction.By optimizating data storage,it increases data encryption protection and authentication mechanism in the Internet of things platform.It also reduces data redundancy in the entire blockchain network,and improves its attribute of distribution.This paper designed and implemented a decentralized application of the Internet of things.Established a new business model based on intelligent blockchain contracts:data transaction between users,data transactions between users and the Internet of things devices,and data transactions between each Internet of things devices.At the same time,the safety and privacy of transactions in the block chain system are guaranteed.By the design of intelligent contract,flexibility and credibility of the transactions are greatly increased.Meanwhile further analysis and testing are carried out for the accuracy design of the contracts.Through actual operations and experimental comparison of the system,this paper proves the correctness and validity of the improved system design scheme for the Internet of thing.
