摘要
区块链是一种分布式的数据库,具有去中心化和去信任化的核心特征,近年来受到高度关注,得到了广泛应用。但作为一项新兴技术,区块链同时存在不可忽视的安全风险。本文从区块链关键技术出发,提出四层技术体系,逐层分析了区块链应用面临的挑战和安全风险,并形成通用的分层安全技术体系。该安全技术体系可用于指导区块链应用建设、保障区块链应用安全和促进安全技术的进一步发展。
As a distributed database,blockchain is fully distributed,decentralized and de-trusted.It has been attracted by many researchers in recent years,and has also been widely used.However,as an emerging technology,there are a lot of challenges and security risks in the development of blockchain.After an introduction to the technology architecture we proposed here,we analyze the security risks faced by the blockchain application layer by layer.As a result,we put forward a universal layered security technology architecture.This architecture is useful to enhance the security of a blockchain application.At the same time,it can also promote the development of blockchain security technologies.
