面向大数据应用的区块链解决方案综述

Survey on Blockchain Solution for Big Data

信息时代背景下,各行各业产生的数据量成倍增加,这些数据具有总量庞大、结构复杂、难于管理等特点。区块链作为一门新的技术,与传统的数据管理方式相比具有去中心化、去信任化和数据加密等优势,能够较好地解决大数据应用中存在的数据管理问题。文章重点介绍了区块链技术在个人数据管理、数字财产保护、物联网通信和医疗数据共享4个大数据场景下的应用情况,讨论了每种大数据应用场景中存在的一些难以解决的问题,并对基于区块链技术解决这些问题的一些新颖方案进行了简要综述,最后指出未来区块链在大数据应用中的重要发展方向。

In the information age,data generated from all walks of life has multiplied.These data have the characteristics of enormous quantity,complicated structure and difficulty to manage.Blockchain,as a new emerging technology,compared with traditional data management methods,owns the advantages of decentralization,trustlessand data encryption.Also,it can solve the data management issues smoothly in big data application.This paper focused on situation of application blockchain technology in four parts of personal data management,digital property protection,IoT communication and medical data sharing.Moreover,some difficult problems in each big data application were discussed and some novel solutions for above problems based on blockchain technology were summarized.Finally,this paper pointed out some important development directions of future blockchain applications in big data field.
