背景技术Background technique
数字货币是一种基于区块链技术的密码货币，与传统电子货币相比，它具有去中心化、账本公开、交易匿名等特点。正因为数字货币的匿名性特点，数字货币被越来越多的不法分子关注，并用于赌博、传销、资金盘、洗钱等非法金融活动，对于监管机构来说，他们很难从交易中获取数字货币交易者的用户身份信息，这给相关部门的监管和打击违法犯罪活动带来很大的困扰。Digital currency is a cryptocurrency based on blockchain technology. Compared with traditional electronic currency, it has the characteristics of decentralization, open ledger, and transaction anonymity. It is precisely because of the anonymity of digital currency that more and more criminals pay attention to digital currency and use it for illegal financial activities such as gambling, pyramid schemes, fundraising, and money laundering. For regulators, it is difficult for them to obtain digital currency from transactions. The user identity information of currency traders has brought great trouble to the supervision of relevant departments and the fight against illegal and criminal activities.
现在在日常生活中，使用数字货币进行交易已经越来越多地出现在日常生活中，保证数字货币的交易安全是正待解决的问题.Now in daily life, the use of digital currency for transactions has increasingly appeared in daily life, and ensuring the transaction security of digital currency is a problem to be solved.
