Research On Blockchain Development Situation And Countermeasures

In 2008,Satoshi Nakamoto published "Bitcoin:A Peer-toPeer Electronic Cash System",in which Blockchain is first proposed.Over the past decade,we have witnessed the birth and development of Blockchain.And Blockchain achieves immutable distributed ledger by the decentralized way,with the characteristics of anonymity,decentralization,immutability,and traceability.It constructs a new credible large-scale collaboration mode to solve the trust problem in the digital economy,which has been placed high expectations by society.Therefore,the development trends of blockchain technology is a problem worthy of attention and consideration.In spite of numerous academic studies on different aspects to Blockchain technology problems,such as the technical architecture,security and privacy,and network security,it is still a lack of all-round,multi-dimension,deep-seated overview of Blockchain technology,including the technical,application,policy and development level.We study and analyze the research status and development trends of Blockchain from multiple perspectives by the investigation of numerous literature,review the challenges and future trends in the development comprehensively,professionally and systematically,so as to promote a better understanding of the technology,application,policy and development of Blockchain.This dissertation mainly focuses on the generation and technology overview of Blockchain,the research,application and the policies and regulations from global perspectives,Blockchain situation auto analysis framework,Blockchain illegal transactions addresses classification,risk classification regulation model,as well as the challenges and countermeasures.In the beginning of the dissertation,the basic theory of Blockchain is elaborated,and the theoretical basis and technology for the birth of Blockchain are summarized.And this article introduces the development of Blockchain since its birth and definition of Blockchain,and summarizes the theoretical and technological basis of Blockchain.Then,the structure of block,the generation of transaction address and the process of transaction are summarized,and the principle of blockchain transaction is introduced from the inside to the table.In addition,the six-layer architecture,the characteristics and classification of Blockchain are discussed and analyzed.The overview of the Blockchain technology,as the underlying theory of the development situation analysis,lays a solid foundation for the situation analysis at all levels of Blockchain.This dissertation analyzes the development trend of Blockchain in academic,application and national policies.In academic research,the results related to Blockchain in the four major literature databases and the opening of Blockchain laboratories in universities are investigated and analyzed,revealing the overall development status of Blockchain in the academic field.Moreover,an in-depth investigation is carried out from consensus algorithm,smart contract,security and privacy,and scalability directions,and the development trend of Blockchain technology research is analyzed and summarized,which provides reference for academic research on Blockchain,for judging the academic development trend of Blockchain.In application,the data of global Blockchain practical application projects are collected and sorted.According to the frequency of application,the application scenarios and characteristics of projects in various fields are described respectively from five directions of finance,Internet of things,supply chain,medical treatment and government affairs.And the current Blockchain technology project development trend is summarized,for the study on the overall trend of Blockchain development to pave the way.In the attitude and implementation policies of various countries around the world,the attitude of each country towards Blockchain and the situation of issuing white papers are investigated.The policy trends of relevant departments around the world on Blockchain in recent years are analyzed and summarized respectively from four regions,according to the geographical importance and the management measures of different countries on the application and development of Blockchain technology.On the basis of the aforedmentioned theoretical analysis of three aspects of Blockchain,this dissertation designs a data automatical analysis framework.After data selection,data processing and the optimization of feature engineering,the framework uses machine learning and neural network methods to train the data in classification model.Through experiments and evaluation,the training results and feature statistics results are finally obtained.In the experimental process,a variety of models are selected for comparative evaluation,the combination of feature metrology and knowledge mapping proves that the framework can obtain the results of classification,research hotspots,research literature and other aspects.This framework attempts to use cutting-edge technologies such as machine learning to automatically classify and statistically analyze relevant data,providing innovative methods for subsequent development trend analysis in the direction of blockchain.Besides,the classification scheme of illegal transaction address of Blockchain is proposed,in which the illegal transaction address of block chain in the dark net is classified.It analyzes the development trend of illegal transaction of Blockchain in the dark net.Furthermore,this dissertation presents a Blockchain risk classification supervisory model,defines the supervision level and its regulation ways,and analyzes the risk of Blockchain in health,energy,financial.In this process,the risk corresponding to the level of supervision by risk calculation is made,and the supervision level is effectively adjusted by the feedback mechanism.The model can be widely available to different scenarios of Blockchain,providing an effective evaluation method for Blockchain regulation.At the last part,considering the situation analysis results of academic research,project application,support and regulatory policies,the current and future challenges of blockchain are analyzed in detail from the technical and application aspects of blockchain.Threrfore,this dissertation puts forward countermeasures in terms of technology,application and national policies,focusing on the core technology breakthrough,application scale,application concept transformation,universal environment creation and regulatory mechanism improvement,so as to boost the innovation and development of Blockchain technology and industry.
