具体实施方式
为了使本领域技术人员更好地理解本说明书实施例中的技术方案，下面将结合本说明书实施例中的附图，对本说明书实施例中的技术方案进行详细地描述，显然，所描述的实施例仅仅是本说明书的一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于保护的范围。
以下结合附图，详细说明本说明书各实施例提供的技术方案。
图1是本说明书实施例提供的一种基于中心化结算与区块链存证的交易方法的流程示意图，包括以下步骤：
S100：指定成员节点接收包含支出用户的支出用户标识、指定资源数额和收入用户的收入用户标识的交易请求。
在本说明书实施例中，区块链网络包括若干成员节点。需要说明的是，在本文中，“节点”可以是由管理方(人或机构)管理的一个设备或多个设备，各成员节点分别对应的管理方通常不同。
在本说明书实施例中，用户在指定成员节点上注册有虚拟资源账户。其中，所述指定成员节点可以根据实际业务需要指定。例如，假设所述区块链网络是由10个金融机构(包括银行、电子支付平台等)组成的联盟链网络，可以将电子支付平台管理的成员节点指定为指定成员节点，用户在电子支付平台注册有虚拟资源账户。
需要说明的是，用户在所述指定成员节点上注册的虚拟资源账户实际上是在所述指定成员节点的关系型数据库中进行维护的。
还需要说明的是，本文中所述的虚拟资源不限于电子货币，还可以是积分、游戏币、虚拟物品等。总之，根据实际业务规则，用户之间可以以任何虚拟资源为交易媒介进行交易。
在步骤S100中，指定成员节点，可以接收支出用户发送的交易请求，也可以接收收入用户发出的交易请求。其中，所述交易请求通常包含支出用户的支出用户标识、指定资源数额和收入用户的收入用户标识，所述支出用户是支出所述指定资源数额的用户，所述收入用户是收入所述指定资源数额的用户。
S102：根据所述交易请求，进行交易可行性验证，并在验证通过后，执行账户余额修改操作。
在本文中，交易可行性验证是指，对交易是否合理可执行进行验证，主要包括对支出用户的账户余额是否充足进行验证。此外，在实践中，根据实际业务规则，也可以对交易的其他事项也可以是可行性验证的内容，例如，支出用户是否有权限。若通过验证，则说明交易是合理可执行的。
若指定成员节点针对交易请求进行可行性验证通过，则进行执行账户余额修改操作，也就是从所述支出用户标识对应的虚拟资源账户中扣除所述指定资源数额，并向所述收入用户标识对应的虚拟资源账户中增加所述指定资源数额。
S104：生成用于记录所述账户余额修改操作的日志文件，并向所述区块链网络广播所述日志文件。
在本步骤S104中，指定成员节点可以生成用于记录上述账户余额修改操作的日志文件。此处需要说明的是，日志文件是用于记录软件系统(如windows系统、业务逻辑处理系统、数据库管理系统等)的操作事件的记录文件或文件集合，日志文件一般是是后缀名为.log的文件。
所述指定成员节点生成所述日志文件后，可以向所述区块链网络广播所述日志文件，使得各成员节点基于共识机制将所述日志文件发布至区块链。
此处需要说明的是，所述区块链网络并不需要根据所述日志文件，对所述交易请求的可行性进行验证。各成员节点基于共识机制，将所述日志文件发布至区块链即可。
还需要说明的是，在本说明书实施例中，不对步骤S102和步骤S104的执行顺序进行限制。可以在执行步骤S102后，再执行步骤S104，也可以在执行步骤S104后，再执行步骤S102，还可以同时执行步骤S102和S104。
通过图1所示的基于中心化结算与区块链存证的交易方法，针对一笔交易，所述指定成员节点执行交易结算时产生的日志文件会被发布至区块链进行存证，相当于中心化结算平台存储的用户账户的收支记录会被发布至区块链进行存证。因此，用户账户的收支记录难以被篡改，可以作为可信的对账凭证。
图2a是本说明书实施例提供的一种基于中心化结算与区块链存证的交易方法的流程示例图。如图2a所示，区块链网络由多个(图中示出6个)成员节点组成，其中，实心点为指定成员节点，空心点为除指定成员节点外的其他成员节点。支出用户可以发起一笔交易，向指定成员节点发送交易请求，指定成员节点先在本地进行账户余额修改操作，并生成记录所述账户余额修改操作的日志文件，然后，将所述日志文件广播至全网，使得各成员节点将所述日志文件发布至自身的区块链。值得强调的是，指定成员节点需要对交易进行可行性验证，而所述区块链网络并不需要对交易进行可行性验证。
此外，在本说明书实施例中，所述指定成员节点可以根据所述日志文件，采用哈希算法生成所述日志文件对应的日志文件摘要，然后向所述区块链网络广播所述日志文件和所述日志文件摘要，使得各成员节点基于共识机制将所述日志文件和所述日志文件摘要发布至区块链。
另外，所述指定成员节点可以将所述日志文件摘要发送给所述支出用户和/或所述收入用户，以便所述支出用户和/或所述收入用户使用所述日志文件摘要向区块链查询所述日志文件。
众所周知，针对一段信息，执行哈希运算可以得到这段信息的摘要(一段字符串)，可以唯一标识这段信息。因此，所述日志文件摘要可以作为所述日志文件的标识，将所述日志文件摘要提供给所述支出用户和/或所述收入用户后，所述支出用户或所述收入用户就能够以所述日志文件摘要为线索，向区块链查询所述日志文件，以确定所述指定成员节点已经执行过所述账户余额修改操作。
实践中，所述日志文件被广播给各成员节点之后，会被各成员节点分别存入自己的缓存中(或称交易池)中，当满足指定的共识触发条件时(如经过指定周期)，各成员节点会基于共识机制，选举一个成员节点从交易池中捞取若干日志文件和相应的日志文件摘要打包成区块，并将该区块向全网广播，使得各成员节点将该区块分别发布至区块链，至此，上述的日志文件和日志文件摘要才会被存证。
因此，进一步地，在本说明书实施例中，所述指定成员节点可以在确定所述日志文 件被发布至区块链之后，再将所述日志文件摘要发送给所述支出用户和/或所述收入用户。
这种情况下，支出用户和/或收入用户当接收到指定成员节点发送的日志文件摘要时，意味着交易成功。若支出用户和/或收入用户未接收到所述日志文件摘要，则哪怕所述指定成员节点已经执行了账户余额修改操作，也并不意味着交易成功(因为日志文件还未被发布至区块链)。
此外，所述指定成员节点也可以在确定所述日志文件被打包进区块之后，将所述日志文件摘要发送给所述支出用户和/或所述收入用户。
另外，所述指定成员节点可以包括业务逻辑执行模块、数据库管理模块和区块链功能模块。
其中，所述业务逻辑执行模块负责向外对接用户，根据用户的业务请求处理业务，所述业务逻辑执行模块通常是安装于所述指定成员节点上的软件，也可以是所述指定成员节点的硬件组成部分。
所述数据库管理模块负责对所述指定成员节点的本地数据库进行管理，如修改数据库中的数据。所述数据库管理模块通常是安装于所述指定成员节点上的软件，也可以是所述指定成员节点的硬件组成部分。
所述区块链功能模块是所述执行成员节点接入所述区块链网络的接口，其通常是安装于所述指定成员节点上的软件，也可以是所述指定成员节点的硬件组成部分。
如此，在步骤S100中，所述指定成员节点可以通过所述业务逻辑执行模块接收所述交易请求。在步骤S102中，所述指定成员节点通过所述业务逻辑执行模块，根据所述交易请求，进行交易可行性验证。若验证通过，则通过所述数据库管理模块，执行账户余额修改操作。
在步骤S104中，所述指定成员节点可以通过业务逻辑执行模块生成所述日志文件(参见图2b)，也可以通过所述数据库管理模块生成所述日志文件(参见图2c)。接着，所述指定成员节点可以通过所述区块链功能模块，向所述区块链网络广播所述日志文件，并随后通过所述区块链功能模块，将所述日志文件发布至自身的区块链。
图3是本说明书实施例提供的另一种基于中心化结算与区块链存证的交易方法的流程示意图，包括以下步骤：
S300：所述业务逻辑执行模块接收包含支出用户的支出用户标识、指定资源数额和 收入用户的收入用户标识的交易请求。
在图3所示的方法中，区块链网络包括若干成员节点，用户在指定成员节点上注册有虚拟资源账户，所述指定成员节点包括业务逻辑执行模块、数据库管理模块和区块链功能模块。
S302：所述业务逻辑执行模块根据所述交易请求，进行交易可行性验证，并在验证通过后，向所述数据库管理模块发送账户余额修改指令。
S304：所述数据库管理模块根据所述账户余额修改指令，在数据库中执行账户余额修改操作。
在图3所示的方法中，由所述业务逻辑执行模块负责受理交易请求以及执行模块负责进行交易可行性验证。验证通过后，业务逻辑执行模块可以指令数据库管理模块执行账户余额修改操作，即从所述支出用户标识对应的虚拟资源账户中扣除所述指定资源数额，并向所述收入用户标识对应的虚拟资源账户中增加所述指定资源数额。
S306：所述业务逻辑执行模块生成用于记录所述账户余额修改操作的日志文件，以及将所述日志文件发送给所述区块链功能模块。
在图3所示的方法中，所述业务逻辑执行模块负责生成所述日志文件，并将生成的日志文件发送给所述区块链功能模块。
具体地，可以预先在业务逻辑执行模块中写入日志文件生成逻辑，交由所述业务逻辑执行模块执行。所述日志文件生成逻辑可以不仅包含记录所述账户余额修改操作的逻辑，也可以包含记录其他交易相关信息(如交易时间、交易地点、交易附言等信息)的逻辑。
在图3所示的方法中，所述数据库管理模块执行所述账户余额修改操作后，可以向所述业务逻辑执行模块返回修改成功通知。所述业务逻辑执行模块在接收到所述修改成功通知后，方可生成用于记录所述账户余额修改操作的日志文件。
S308：所述区块链功能模块向所述区块链网络广播所述日志文件，以使各成员节点基于共识机制将所述日志文件发布至区块链。
在步骤S308中，由区块链功能模块负责向区块链网络广播所述日志文件。
此外，在步骤S308中，所述区块链功能模块具体可以根据所述日志文件，采用哈希算法，生成所述日志文件对应的日志文件摘要，然后向所述区块链网络广播所述日志 文件和所述日志文件摘要，以使各成员节点基于共识机制将所述日志文件和所述日志文件摘要发布至区块链。
所述区块链功能模块可以将所述日志文件摘要发送给将所述日志文件摘要发送给所述业务逻辑执行模块，然后，所述业务逻辑执行模块将所述日志文件摘要所述支出用户和/或所述收入用户，以便所述支出用户和/或所述收入用户使用所述日志文件摘要向区块链查询所述日志文件。
进一步地，所述区块链功能模块若确定所述日志文件被发布至区块链，则将所述日志文件摘要发送给所述业务逻辑执行模块。
针对图3所示的方法，需要说明的是，由所述业务逻辑执行模块负责生成所述日志文件，无须对业务逻辑执行模块进行复杂的改造，仅需要在业务逻辑执行模块中写入日志文件生成逻辑即可。此外，由所述业务逻辑执行模块负责生成所述日志文件，还可以实现对日志文件的内容的定制化，如此，所述日志文件不仅用于记录所述账户余额修改操作，还可以用于记录其他交易相关信息。
图4是本说明书实施例提供的另一种基于中心化结算与区块链存证的交易方法的流程示意图，包括以下步骤：
S400：所述业务逻辑执行模块接收包含支出用户的支出用户标识、指定资源数额和收入用户的收入用户标识的交易请求。
在图4所示的方法中，区块链网络包括若干成员节点，用户在指定成员节点上注册有虚拟资源账户，所述指定成员节点包括业务逻辑执行模块、数据库管理模块和区块链功能模块。
S402：所述业务逻辑执行模块根据所述交易请求，进行交易可行性验证，并在验证通过后，向所述数据库管理模块发送账户余额修改指令。
S404：所述数据库管理模块根据所述账户余额修改指令，执行账户余额修改操作，并生成用于记录所述账户余额修改操作的日志文件。
在图4所示的方法中，由所述业务逻辑执行模块负责受理交易请求以及执行模块负责进行交易可行性验证。验证通过后，业务逻辑执行模块可以指令数据库管理模块执行账户余额修改操作，即从所述支出用户标识对应的虚拟资源账户中扣除所述指定资源数额，并向所述收入用户标识对应的虚拟资源账户中增加所述指定资源数额。
在图4所示的方法中，所述数据库管理模块负责生成所述日志文件，并将生成的日志文件发送给所述区块链功能模块。
为本领域技术人员所熟知的是，所述数据库管理模块在针对数据库进行数据修改时，为了保证事务的原子性，一般首先生成记录有数据修改操作的数据库日志，再根据该数据库日志执行数据修改操作。
由此可见，在图4所示的方法中，所述日志文件即是所述数据库日志。并且，所述数据库管理模块可以在执行所述账户余额修改操作之前，生成所述日志文件。
S406：所述数据库管理模块将所述日志文件发送给所述区块链功能模块。
S408：所述区块链功能模块向所述区块链网络广播所述日志文件。
在步骤S408中，所述区块链功能模块根据所述日志文件，采用哈希算法，生成所述日志文件对应的日志文件摘要，然后向所述区块链网络广播所述日志文件和所述日志文件摘要，以使各成员节点基于共识机制将所述日志文件和所述日志文件摘要发布至区块链。
所述区块链功能模块可以将所述日志文件摘要发送给所述数据库管理模块，然后所述数据库管理模块将所述日志文件摘要发送给所述业务逻辑执行模块，所述业务逻辑执行模块将所述日志文件摘要发送给所述支出用户和/或所述收入用户，以便所述支出用户和/或所述收入用户使用所述日志文件摘要向区块链查询所述日志文件。
进一步地，所述区块链功能模块若确定所述日志文件被发布至区块链，则将所述日志文件摘要发送给所述数据库管理模块。此外，所述指定成员节点也可以在确定所述日志文件被打包进区块之后，将所述日志文件摘要发送给所述支出用户和/或所述收入用户。
此外需要说明的是，所述数据库管理模块可以在执行账户余额修改操作后，立即向所述业务逻辑执行模块返回修改成功通知，也可以在执行账户余额修改操作后，暂时不返回修改成功通知，而是待到接收到所述区块链功能模块返回的日志文件摘要后，将所述修改成功通知与所述日志文件摘要一并返回给业务逻辑执行模块。
基于图1所示的基于中心化结算与区块链存证的交易方法，本说明书实施例还对应提供了一种基于中心化结算与区块链存证的交易装置，如图5所示，区块链网络包括若干成员节点，所述装置为任一成员节点，用户在所述装置上注册有虚拟资源账户，所述装置包括：
