摘要/Abstract

摘要：

区块链技术作为一项革命性的新技术受到企业界和学术界的广泛关注和研究。区块链具有透明性、数据完整性、防篡改等优点,在金融、保险、政府、军事等领域有重要应用价值。文章研究利用区块链智能合约设计一个无中心操纵、透明可信的网络互助平台。在此基础上,基于已有的区块链隐私保护技术,提出了网络互助平台的用户隐私保护方法,使得平台用户的身份信息对其他用户都是保密的。

关键词: 区块链, 网络互助, 智能合约, 隐私保护, 环签名

Abstract:

As a revolutionary new technology, blockchain technology has received extensive attention and research from the business and academia community. Blockchain has the advantages of transparency, data integrity, anti-tampering, etc. It has important application value in the fields of finance, insurance, government, and military. This paper studies the use of blockchain smart contracts to design a non-centralized, transparent and trusted network mutual aid platform. Based on this, rely on the existing blockchain privacy protection technology, we propose the user privacy protection method of the network mutual aid platform, making the user's identity information confidential to other users.

Key words: blockchain, network mutual aid, smart contract, privacy protection, ring signature
