区块链应用研究进展

 区块链是基于去中心化的分布式账本技术，可以实现业务活动数据的隐私保护、安全存储及不可抵赖证明。自2009年产生以来，区块链技术逐渐被人们认可并在各行业得到重视和研究。本文总结了区块链的特点、技术，对区块链进行了应用、发展阶段及创业团队分类，对区块链与云计算的关联关系进行了分析。对区块链在世界各国及不同产业的应用研究现状以及目前区块链的学术研究进展进行了综述分析。结果表明，区块链在不同应用领域得到了广泛的探索，然而尚未形成成熟的可以推广的产品，学术研究多数为特点及价值分析，一些学者开发了具体领域的处于测试状态的区块链产品。区块链将颠覆传统的数据库体系及业务交互体系，成为“互联网+”时代信用建设的技术体系保障。

Progress in blockchain application research

Blockchain is a distributed ledger technology based on decentration, and can realize business activity data's privacy protection, secure storage, and non repudiation proof. Since it was produced in 2009, the blockchain technology has been gradually accepted by people and received attention from almost every industry. In the paper we summarize the characteristics and technology of blockchain, and classify blockchain by application, development stage, and entrepreneurial team. We discuss the relation between blockchain and cloud computing. Moreover, we review the application research status on blockchain in the world and in different industry sectors, and summarize the current blockchain's academic research progress. It is indicated that blockchain has got extensive exploration in different application areas while it is still not mature or a popularized product, Although the current academic research results mainly focus on characteristics and value analysis, some scholars have developed concrete area's test status blockchain products. We believe blockchain will subvert the traditional database system and business interaction system and will become the technology system guarantee for the Internet plus era's credit construction.
