摘要
区块链技术是一种新兴的分布式共享数据库技术。随着比特币等数字加密货币的兴起,它受到广大学者的关注。区块链是一个公开、透明、可追溯、不可篡改的分布式总账系统,在医疗、教育、智能财产等众多领域有着巨大的应用前景。通过比特币货币系统介绍区块链技术的核心原理及其运作机制,结合国内外研究现状,阐述区块链技术面临的挑战,最后对区块链技术在数据保密中的应用进行展望。
Block-chain technology is a new shared distributed database technology,and with the rise of digital crypto-currencies,such as bitcoin,attracts much attention from many scholars.Block chain,as an open,transparent,traceable and non-tampered distributed general-ledger system,has great application prospects in many fields,such as medical,education,intelligent property and so on.The core principle and operating mechanism of block-chain technology are described via the introduction of bitcoin currency system.Meanwhile,combined with the current research status both at home and abroad,the challenges faced by block-chain technology are expounded.Finally,the application of block-chain technology in data secrecy is prospected.
