具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例提供的虚拟币存储交易系统的结构示意图，如图1所示，本发明实施例提供的虚拟币存储交易系统，包括第一终端1和第二终端2，其中：
所述第一终端1处于绝网状态，可以通过定制，以使得第一终端1不具有网络连接的功能，用于根据存储所述虚拟币钱包的种子密码或根据所述种子密码和自定义密码生成用于加密所述虚拟币钱包的私钥，即每个种子密码可以对应多个私钥，虚拟币的类型可以是比特币、莱特币等，虚拟币钱包可以理解为在第一终端1注册的账户，种子密码可以在第一终端1中随机生成，具体的生成方法是该领域内的成熟技术，这里不再赘述，一个种子密码可以对应多种不同类型的虚拟币，种子密码获得后需要备份，切勿将种子密码透露给其他人，种子密码丢失则导致该钱包内的虚拟币丢失，具体的备份方式可以抄写记录或复制并粘贴到文档等。自定义密码可以是生成种子密码后提示用户自主设置的密码，可以包括若干个字母或数字。私钥可以是由种子密码和自定义密码通过椭圆曲线加密算法生成或由种子密码通过椭圆曲线加密算法生成，通过私钥可以保证钱包内的虚拟币的安全存储。并生成与所述私钥对应的带有标识码的存储地址，以接收向所述存储地址支付的所述虚拟币；存储地址可以理解为存储钱包内虚拟币的地址，不同类型的虚拟币可以对应不同的存储地址，即比特币对应一类存储地址，莱特币对应另一类存储地址；同一种类型的虚拟币也可以对应多个不同的存储地址，即虚拟币类型都是比特币的也可以对应多个不同的 存储地址；其他的终端可以通过扫描该存储地址的标识码向该存储地址支付虚拟币，即该存储地址的标识码提供了外界向该钱包的支付入口。
还用于根据输入的支付地址，向所述支付地址对应的第三方支付所述虚拟币。支付地址可以显示在第一终端1的显示界面上，第三方可以理解为接收由第一终端1内钱包支付虚拟币的其他终端。
所述第二终端2处于联网状态，用于向所述第三方发布支付所述虚拟币的交易信息，并根据不同的虚拟币类型发送至相关区块链网络，即虚拟币类型为比特币的，发送至与比特币相关的区块链网络；虚拟币类型为莱特币的，发送至与莱特币相关的区块链网络。还可以用于扫描第一终端1上的识别码，以获取更新后的虚拟币金额，第二终端2通过网络连接第三方，从而实现了支付交易的过程，交易信息可以包括交易时间、交易金额、手续费等。
所述第一终端1与所述第二终端2互相扫描显示界面上的标识码，以进行信息交互。在相应的第一终端1或第二终端2需要开通相机权限，即：第二终端2可以扫描第一终端1显示界面上的标识码(要在第二终端2开通相机权限)，第一终端1可以扫描第二终端2显示界面上的标识码(要在第一终端1开通相机权限)，进而通过标识码传输信息，而不通过电磁波传输信息，从而保证了私钥的安全。
本发明实施例提供的虚拟币存储交易系统，能够保证虚拟币存储交易过程中的安全。
在上述实施例的基础上，所述标识码为二维码，还可以包括条形码等，此处不作具体限定。
本发明实施例提供的虚拟币存储交易系统，通过将标识码选为目前常用的二维码，有利于该系统的广泛使用。
在上述实施例的基础上，所述私钥还用于生成公钥，所述公钥用于生成所述存储地址，其中所述公钥为一串二进制代码。
本发明实施例提供的虚拟币存储交易系统，能够通过公钥更加便于第三方获取该存储地址，从而有利于该系统的推广。
在上述实施例的基础上，所述公钥和所述私钥通过椭圆曲线加密算法成对生成。私钥可以和公钥一样，都包含一串二进制代码。但是公钥可以 对外公开显示，私钥永久隐藏。
本发明实施例提供的虚拟币存储交易系统，通过椭圆曲线加密算法成对生成公钥和私钥，使得生成的私钥难以被破译，使得虚拟币存储更加安全。
在上述实施例的基础上，所述支付地址预存于所述第一终端1内，并设置有标记。由于每次向第三方支付虚拟币都要输入支付地址，因此可以将比较常用的支付地址预存在第一终端1内，标记可以是对应于支付地址的名称等，以方便支付过程的操作。
本发明实施例提供的虚拟币存储交易系统，通过将支付地址存于第一终端内，并设置标记，方便了支付的过程。
在上述实施例的基础上，所述第一终端1还用于使用所述自定义密码恢复所述种子密码。当种子密码忘记，可以通过自定义密码恢复种子密码。
本发明实施例提供的虚拟币存储交易系统，通过种子密码恢复自定义密码，使得即便忘记自定义密码还能继续进行该系统的使用，从而使得该系统更加便于使用。
本发明实施例提供了一种使用上述系统的方法，包括：
