Description

基于区块链的子账户交易处理方法、系统、设备及介质

技术领域
本申请涉及区块链技术领域，涉及了一种基于区块链的子账户交易处理方法、系统、计算机设备及存储介质。
背景技术
目前，区块链账户中，一个私钥对应一个账户，用户发起转账请求时，通过私钥对转账金额和目的账户地址进行签名，在转账请求中携带该签名以及私钥对应的公钥。区块链节点接收到该转账请求后，通过该转账请求携带的公钥对转账请求中的签名进行解密，得到转账金额及目的账户地址。然后通过非对称加密算法对该公钥进行运算，得到用户的账户地址，然后从用户的账户地址中转出该转账金额，并在目的账户地址中转入该转账金额。
发明人意识到由于一个私钥对应一个账户，若用户具有多个账户，则用户需要记住多个私钥，容易记混或者丢失。
发明内容
本申请提出一种基于区块链的子账户交易处理方法、系统、计算机设备及存储介质，将用户的多个账户构建为一个主账户和多个子账户，子账户地址包括主账户地址。多个账户采用相同的私钥，避免多个私钥记混或忘记的情况。根据子账户地址和主账户地址确定子账户是否为用户拥有的账户，在账户被盗取的情况下能及时识别出来，避免用户损失。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。
本申请的一些实施例提供了一种基于区块链的子账户交易处理方法，在该方法中将用户拥有的多个账户构建为一个主账户和多个子账户的形式，子账户对应的子账户地址中包括主账户对应的主账户地址，用户只需要记忆主账户对应的私钥，通过一个私钥，结合主账户地址和子账户地址，可以实现对子账户的操作。因此用户的多个账户之间无需再进行私钥的区分，多个账户可以采用相同的私钥，用户只需记住一个私钥，通过这一个私钥可以对自己的任意子账户进行操作，避免了多个私钥记混或忘记的情况。
通过本申请实施例提供的方法进行子账户交易处理之前，首先通过如下步骤S1-S4的操作在区块链中创建用户的子账户，具体包括：
步骤S1：终端获取用户的主账户对应的主账户地址。
当用户需要在区块链中创建子账户时，用户可以向终端提交自己的主账户地址，主账户地址可以为用户选定的主账户的账号。终端接收用户提交的主账户地址。
步骤S2：终端根据主账户地址，生成子账户地址。
根据主账户地址来生成子账户地址，以便后续进行子账户转账时可以根据主账户地址 和子账户地址来确定该子账户是否确实是发起转账请求的用户拥有的账户。从而在用户的账户被其他人盗取的情况下能够及时识别出来，避免给用户的账户余额造成损失。
终端具体通过如下步骤S21和S22的操作来生成子账户地址，具体包括：
步骤S21：终端生成一个临时字符串。
本申请实施例可以通过随机数生成器生成一个随机数，将该随机数确定为临时字符串。或者，用户向终端输入随机信息，该随机信息可以为用户的姓名、昵称、电话、住址等用户信息，或者用户随机输入的字符序列等。只要确保创建每个子账户时用户输入的随机信息各不相同即可。终端获取用户输入的随机信息，对该随机信息进行哈希运算，得到临时字符串。
可以每次生成一个随机数作为临时字符串，或者对用户输入的随机信息进行哈希运算得到临时字符串。如此确保用户的每个子账户的账户地址均不相同。
步骤S22：终端在主账户地址的字符序列的预设位置处添加临时字符串，得到子账户地址。
通过步骤S21生成临时字符串之后，终端在主账户地址的字符序列的预设位置处添加该临时字符串，预设位置可以为主账户地址的字符序列的开始位置、结束位置或者中间位置等。将临时字符串添加到主账户地址中后得到一个新的地址，将该新的地址作为当前需要创建的子账户对应的子账户地址。
通过在主账户地址中添加临时字符串的形式生成子账户地址，使得子账户地址中包括主账户地址，从而使得后续进行子账户转账时可以根据主账户地址和子账户地址来确定该子账户是否确实是发起转账请求的用户拥有的账户。生成子账户地址后，通过如下步骤S3的操作在区块链中创建子账户。
步骤S3：终端发送账户创建请求给区块链节点，该账户创建请求包括上述生成的子账户地址。
终端生成子账户地址后，发送账户创建请求给区块链节点，在该账户创建请求中携带上述生成的子账户地址。
步骤S4：区块链节点接收终端发送的账户创建请求，在区块链中创建用户的子账户。
区块链节点接收终端发送的账户创建请求，该账户创建请求中包括用户的姓名、电话、URL(Uniform Resource Locator，统一资源定位系统)等用户信息中的一种或多种，以及包括上述生成的子账户地址。在各个区块链点中存储该子账户地址与用户信息的对应关系。将子账户地址与用户信息的对应关系存储在区块链节点中就完成了该子账户的创建过程，区块链节点可以向终端返回创建成功通知。
在本申请的另一些实施例中，当用户需要在区块链中创建子账户时，终端获取用户的主账户对应的主账户地址之后，也可以直接发送账户创建请求给区块链节点，该账户创建请求包括用户的主账户地址及用户信息。区块链节点接收到该账户创建请求之后，由区块链节点按照步骤S2的方式生成一个子账户地址，然后。在各个区块链点中存储该子账户地址与用户信息的对应关系，完成子账户的创建过程，并将子账户对应的子账户地址返回给用户的终端。
用户拥有的每个子账户都可以通过上述方式在区块链中完成子账户的创建。创建子账户之后，用户即可以对该子账户进行转账操作。参见图1，具体地通过如下步骤S101-S106的操作来对子账户进行转账操作。
步骤S101：终端接收用户提交的私钥及子账户对应的转账信息，该转账信息包括子账户对应的子账户地址，子账户地址中包括用户的主账户对应的主账户地址。
在本申请实施例中，用户在创建主账户时，终端根据用户的主账户地址，通过预设非对称加密算法生成了一个密钥对，并在终端存储了该密钥对包括的公钥。私钥由用户自己记 住。预设非对称加密算法可以为RSA(RSA algorithm)、DSA(Digital Signature Algorithm，数字签名算法)、ECC(Elliptic curve cryptography，椭圆加密算法)等。
当用户需要从子账户往其他账户转账时，终端显示转账界面，用户在转账界面中提交子账户对应的子账户地址、目的账户地址及转账金额，以及输入用户的私钥。上述转账信息可以包括子账户地址、目的账户地址及转账金额。
步骤S102：终端通过用户提交的私钥对转账信息进行签名，得到转账信息密文。
终端通过用户输入的私钥对子账户地址、目的账户地址及转账金额等转账信息进行加密，得到转账信息密文。
步骤S103：终端发送子账户对应的转账请求给区块链节点，该转账请求包括转账信息密文及预存的公钥。
终端从本地获取预先存储的公钥，根据该公钥和步骤S102生成的转账信息密文，生成转账请求，将该转账请求发送给区块链节点。
步骤S104：区块链节点接收用户的终端发送的子账户对应的转账请求，根据该转账请求，获取子账户对应的子账户地址和用户的主账户地址。
具体通过如下步骤S1041-S1043的操作来获取子账户地址和主账户地址：
步骤S1041：区块链节点从转账请求中获取公钥和转账信息密文。
步骤S1042：区块链节点通过公钥对转账信息密文解密，得到转账信息，该转账信息包括子账户地址。
区块链节点通过公钥对转账信息密文解密，得到子账户地址、目的账户地址及转账金额等转账信息。
步骤S1043：区块链节点通过预设非对称加密算法对公钥进行运算，得到用户的主账户地址。
由于公钥是通过预设非对称加密算法对用户的主账户地址进行运算得到的，因此通过预设非对称加密算法对公钥进行反向运行，能够得到用户的主账户地址。
通过转账请求能够获得该转账请求对应的子账户地址及用户的主账户地址，以便后续根据子账户地址和主账户地址确定当前的子账户是否为用户拥有的账户。
步骤S105：区块链节点根据子账户地址和主账户地址，确定该子账户是否为用户拥有的子账户。
区块链节点比较子账户地址和主账户地址，确定子账户地址中是否包括主账户地址。具体地，区块链节点从子账户地址的第一个字符开始遍历，比较子账户地址的第一个字符是否与主账户地址的第一个字符相同，如果是，则比较子账户地址的第二个字符是否与主账户地址的第二个字符相同。如果子账户地址的第一个字符与主账户地址的第一个字符不相同，则比较子账户地址的第二个字符是否与主账户地址的第一个字符相同。如此依次遍历子账户地址和主账户地址的字符，若遍历出子账户地址中包括主账户地址中的所有字符，则确定子账户地址中包括主账户地址，进而确定该子账户为该用户拥有的子账户。如果确定出子账户地址中并不包括主账户地址的全部字符，则确定子账户不是用户拥有的子账户。
通过上述操作能够准确地确定出当前发起转账请求的子账户是否是当前用户拥有的子账户，若确定出该子账户不是该用户拥有的子账户，则表明该用户想要从其他人的子账户中转账，则将损害其他人的财产安全。本申请实施例能够确定出该子账户是否为当前用户拥有的子账户。从而在用户的账户被其他人盗取的情况下能够及时识别出来，避免给用户的账户余额造成损失。
由于用户的子账户地址都是通过主账户地址加临时字符串的形式，所以用户的每个子账户的地址中都包括该用户的主账户地址，因此通过确定当前发起账户请求的该子账户的地址中是否包括用户的主账户地址，能够确定出该子账户是否为当前用户拥有的子账户。从 而在用户的账户被其他人盗取的情况下能够及时识别出来，避免给用户的账户余额造成损失。
步骤S106：区块链节点若确定子账户为用户拥有的子账户，则对该转账请求进行转账处理。
若区块链节点确定该子账户为用户拥有的子账户，则可以进行转账。具体地，根据步骤S1042中获得的转账信息中包括的子账户地址和转账金额，从该子账户地址对应的账户余额中减去该转账金额。以及，根据转账信息包括的目的账户地址和转账金额，从该目的账户地址对应的账户余额中加上该转账金额。
通过上述方式从该子账户向目的账户转账之后，根据该子账户地址、转账金额和目的账户地址，生成转账成功通知，该转账成功通知中包括该子账户地址、转账金额、目的账户地址以及用于提示转账成功的提示信息。向该用户的终端发送转账成功通知，以便用户能实时获知该子账户的余额变动情况。
通过上述方式完成子账户的转账之后，还根据转账金额、目的账户地址、子账户地址，生成该转账请求对应的转账记录。在各个区块链节点中存储子账户地址与转账记录的对应关系。基于区块链的可追溯、不可篡改的特性，将子账户的转账记录存储在区块链节点中，能够确保子账户的转账记录的真实性，避免账本作假。
若区块链节点确定该子账户不是该用户拥有的子账户，则不能进行转账操作，丢弃该转账请求，并发送转账失败通知给该用户的终端。本申请实施例中，区块链节点还可以根据该子账户地址，从该子账户地址对应的账户信息中获取该子账户的真实用户的URL。根据获取的URL，向该子账户的真实用户发送警示信息，该警示信息用于提示该真实用户有其他人尝试从该子账户转账，以便提示用户该子账户存在安全风险，以使该用户对该子账户及时采取冻结操作，或者将子账户中的余额转走，或者修改自己的密钥等，从而在发生子账户被盗取时避免给用户的账户余额造成损失。
在本申请实施例中，将用户拥有的多个账户构建为一个主账户和多个子账户的形式，子账户对应的子账户地址中包括主账户对应的主账户地址。用户只需要记忆主账户对应的私钥，通过一个私钥，结合主账户地址和子账户地址，可以实现对子账户的操作。因此用户的多个账户之间无需再进行密钥的区分，多个账户可以采用相同的密钥，用户只需记住一个私钥，通过这一个私钥可以对自己的任意子账户进行操作，避免了多个密钥记混或忘记的情况。区块链节点根据转账请求获取子账户地址和用户的主账户地址，根据子账户地址和主账户地址确定当前的子账户是否为用户拥有的子账户。只有确定该子账户为用户拥有的子账户后才进行转账处理，从而在用户的账户被其他人盗取的情况下能够及时识别出来，避免给用户的账户余额造成损失。
