摘要:

区块链具有不可被篡改和去中心化的特性,将其应用到存储系统中,有助于提高存储系统的数据安全性和系统可扩展性。区块链技术与存储技术的融合主要分为 3 方面:基于区块链构建的去中心化存储系统、基于区块链优化已有系统的存储性能和区块链系统自身的存储方法与优化。对这些工作进行了综述,讨论对比了当前典型的采用了区块链技术的存储系统,总结了区块链存储面临的主要挑战,并展望了区块链存储的发展方向。

关键词: 区块链存储, 去中心化, 分布式存储, 数据安全性, 可扩展性

Abstract:

Blockchain′s characteristics of non-temper and decentralization can be utilized to improve the data security and scalability of storage systems,called blockchain storage.These works that combine storage with blockchain technology,are mainly divided into three categories:decentralized storage systems based on blockchain,improve the performance of existing storage systems based on blockchain,and the underlying storage strategies of blockchain.These works were summarized,the current blockchain storage systems were compared,the main challenges that blockchain and storage being facing were discussed and its future development was forecasted.

Key words: blockchain storage, decentralization, distributed storage, data security, scalability
