具体实施方式
为了使本技术领域的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清楚、完整地描述，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， 都应当属于本文件的保护范围。
图1为本说明书实施例提供的一种资产转移方法的应用场景示意图，如图1所示，该场景包括第一用户的第一客户端、接入区块链的区块链节点、交易平台；其中，第一客户端可为手机、平板电脑、台式计算机、便携笔记本式计算机等(图1中仅示出手机)。
具体的，当第一用户需要对其拥有的资产进行转移时，操作其第一客户端；第一客户端响应于第一用户的资产转移操作，根据确定的资产转移信息向区块链节点发送资产转移请求；区块链节点根据接收到的资产转移请求，调用区块链中的第一智能合约，基于第一智能合约根据资产转移信息，对待转移资产进行锁定处理；区块链节点向指定的交易平台发送待转移资产的资产信息；交易平台发布接收到的资产信息，以供各用户进行查阅，并确定与第一用户进行交易的第二用户；当区块链节点从第一客户端获取到资产转移确认信息时，根据资产转移确认信息对锁定的待转移资产进行转移处理，以将待转移资产转移给第二用户；其中，资产转移确认信息包括第二用户的相关信息；区块链节点向第一客户端发送资产转移结果信息。由此，区块链节点在接收到资产转移请求时，通过对待转移资产进行锁定处理，并在获取到资产转移确认信息时，对锁定的待转移资产进行转移处理，使得同一资产仅对应一笔交易，避免了因同一资产涉及多笔交易而导致交易失败的问题，确保了各交易的有效进行。
基于上述应用场景架构，本说明书一个或多个实施例提供了一种资产转移方法。图2为本说明书一个或多个实施例提供的一种资产转移方法的流程示意图，图2中的方法能够由图1中的区块链节点执行，如图2所示，该方法包括以下步骤：步骤S102，接收第一客户端发送的资产转移请求；其中，资产转移请求基于第一用户的资产转移操作所发送，资产转移请求包括资产转移信息；其中，资产转移信息随待转移资产的不同而不同。例如，待转移资产为货物仓单，相应地，资产转移信息可包括待转移资产的第一标识信息、第一用户的用户信息等；又如，待转移资产为某类型的积分，相应地，资产转移信息可包括待转移资产的第一标识信息、转移数量、第一用户的用户信息等。其中，用户信息如用户标识信息等。
步骤S104，调用区块链中的第一智能合约，基于第一智能合约根据资产转移信息，对待转移资产进行锁定处理；步骤S106，向指定的交易平台发送待转移资产的资产信息，以使交易平台基于资产信息确定与第一用户进行交易的第二用户；其中，资产信息随待转移资产的不同而不同。例如，待转移资产为货物仓单，相应地，资产信息可包括该货物仓单所对应的货物的名称信息、产地信息、数量信息等；又如，待转移资产为某类型的积分，相应地，资产信息可包括该积分的类型信息、数量信息等。当交易平台接收到待转移资产的资产信息时，发布该资产信息，以使用户查阅该资产信息，并确定与第一用户进行交易的第二用户。
步骤S108，从第一客户端获取资产转移确认信息，根据资产转移确认信息对锁定的待转移资产进行转移处理，以将待转移资产转移给第二用户；其中，资产转移确认信息包括第二用户的相关信息。
本说明书一个或多个实施例中，区块链节点在接收到第一客户端发送的资产转移请求时，对待转移资产进行锁定处理，并将待转移资产的资产信息发送给指定的交易平台，以使交易平台确定与第一用户进行交易的第二用户；以及，在从第一客户端获取到资产转移信息时，将锁定的待转移资产转移给第二用户。由此，在接收到资产转移请求时， 通过对待转移资产进行锁定处理，有效的避免了在交易平台的链下交易处理过程中，基于其他交易请求对该待转移资产进行链上操作，即避免了因同一资产涉及多笔交易而导致的交易失败问题，确保了各交易的有效进行。
为了便于后续对资产锁定操作的追溯，本说明书一个或多个实施例中，如图3所示，步骤S104包括：步骤S104-2，调用区块链中的第一智能合约，基于第一智能合约根据资产转移信息包括的待转移资产的第一标识信息、表征待转移资产处于锁定状态的状态信息，生成锁定记录信息；步骤S104-4，将锁定记录信息保存至区块链中。
通过将锁定记录信息保存至区块链中，不仅使得锁定操作可追溯，而且在接收到其他涉及待转移资产的交易请求时，能够基于锁定记录信息确定待转移资产所处的锁定状态，从而及时取消该其他交易请求，避免因待转移资产涉及多笔交易而导致的交易失败。
为了在资产转移过程中，验证相关用户对于待转移资产的所有权，本说明书一个或多个实施例中，当确定资产归属于某用户时，生成相应的持有码，并将该持有码、该用户的公钥以及资产的标识信息等对应保存至区块链中。与之对应的，如图4所示，步骤S108包括：步骤S108-2，根据资产转移信息包括的待转移资产的第一标识信息，从区块链中获取第一用户关于待转移资产的第一持有码和第一持有码对应的第一公钥；其中，第一持有码表征待转移资产归属于第一用户；具体的，将待转移资产的第一标识信息与区块链保存的各标识信息进行匹配，若匹配成功，则获取匹配成功的标识信息所对应的第一持有码和第一公钥。
步骤S108-4，根据第一公钥对第一持有码进行加密处理，得到第一持有码的密文；步骤S108-6，将第一持有码的密文发送给第一客户端，以使第一客户端根据第一公钥所对应的第一私钥对第一持有码的密文进行解密处理，得到第一持有码，根据第一持有码生成资产转移确认信息；具体的，当第一客户端接收到区块链节点发送的第一持有码的密文时，根据第一公钥所对应的第一私钥对第一持有码的密文进行解密处理，得到第一持有码；展示该第一持有码，以使第一用户确定该第一持有码是否为自身的第一持有码，并在确定结果为是时，点击展示界面中的确定控件，以确认进行资产转移；第一客户端响应于第一用户的资产转移确认操作，根据第一私钥对第一持有码进行签名处理，得到第一签名数据；根据第一签名数据、待转移资产的第一标识信息及获取的第二用户的第二公钥，生成资产转移确认信息，并将资产转移确认信息发送给区块链节点。
可选地，第二用户私下将其第二公钥告诉第一用户，相应的，获取第二用户的第二公钥包括：响应于第一用户的资产转移确认操作，获取第一用户提交的第二用户的第二公钥。或者，第一客户端响应于第一用户的资产转移确认操作，根据第一用户提交的第二用户的用户信息，从指定机构获取第二用户的第二公钥等。本说明书中，对于第二公钥的获取方式不做具体限定。
步骤S108-8，接收第一客户端发送的资产转移确认信息，根据资产转移确认信息对锁定的待转移资产进行转移处理，以将待转移资产转移给第二用户；其中，资产转移确认信息包括第二用户的相关信息。
通过将第一持有码的密文发送给第一客户端，不仅能够有效的避免第一持有码的外泄；而且，由于第一公钥所对应的第一私钥仅有第一用户持有，因此还能够实现对第一用户的身份的验证。
为了确保待转移资产能够真正的转移至与第一用户进行交易的第二用户，本说明书 一个或多个实施例中，第一用户可将其关于待转移资产的第一持有码私下告知第二用户，或者第二用户操作其第二客户端向第一客户端发送持有码的获取请求以获取第一持有码，从而根据第一持有码获取待转移资产。与之对应的，如图5所示，步骤S108-8可包括以下步骤S108-82至步骤S108-86：步骤S108-82，接收第一客户端发送的资产转移确认信息，调用区块链中的第二智能合约，基于第二智能合约生成第二持有码；步骤S108-84，接收第二客户端发送的资产转移验证信息；其中，资产转移验证信息基于获取的第一持有码所生成；具体的，第二客户端响应于第二用户的资源获取操作，采用第二公钥对应的第一私钥对获取的第一持有码进行签名处理得到第二签名数据；根据第二签名数据、待转移资产的第一标识信息、第二用户的用户信息等，生成资产转移验证信息；向区块链节点发送资产转移验证信息。
步骤S108-86，若对资产转移验证信息验证通过，则将第二持有码发送给第二客户端，以表征待转移资产归属于第二用户。
区块链节点通过将第一持有码的密文发送给第一客户端，以使第一用户确认是否进行资产转移，以及接收第二客户端基于获取的第一持有码所发送的资产转移验证信息；由此，基于第一持有码形成闭环，确保了待转移资产能够从其所属的第一用户转移至与第一用户进行交易的第二用户。
进一步的，为了确保资产转移确认信息来自第一用户，本说明书一个或多个实施例中，生成第二持有码之前还对资产转移确认信息中的第一签名数据进行验证。具体的，如图6所示，步骤S108-82可包括：步骤S108-82-2，接收第一客户端发送的资产转移确认信息，调用区块链中的第二智能合约，基于第二智能合约根据资产转移确认信息中的第一标识信息从区块链中获取对应的第一公钥；步骤S108-82-4，若根据第一公钥对第一签名数据验证通过，则生成第二持有码。
具体的，根据资产转移确认信息中的第一标识信息从区块链中获取对应的第一持有码；以及根据获取的第一公钥对第一签名数据进行验签处理，得到第一持有码；将得到的第一持有码与获取的第一持有码进行匹配，若匹配成功，则确定验证通过，生成第二持有码；若匹配失败，则确定验证未通过，向第一客户端发送资产转移失败信息。其中，持有码的生成规则可在实际应用中根据需要自行设定。
进一步的，为了避免第一用户的第一持有码被其他用户盗用，该其他用户冒充第二用户向区块链节点发送资产转移验证信息，本说明书一个或多个实施例中，如图7所示，步骤S108-82之后还包括：步骤S108-83，将第二持有码与资产转移确认信息中的第二公钥和第一标识信息关联保存至区块链中；与之对应的，如图7所示，步骤S108-86包括以下步骤S108-86-2和步骤S108-86-4：步骤S108-86-2，根据资产转移验证信息中的第一标识信息，从区块链中获取关联保存的第二公钥；
具体的，根据资产转移验证信息中的第一标识信息从区块链中查询关联的最后一个记录信息，确定查询到的记录信息是否为锁定记录信息，若是，则根据资产转移验证信息中的第一标识信息，从区块链中获取关联保存的第二公钥；若否，则向第二客户端发送资产获取失败信息。
步骤S108-86-4，若根据第二公钥对资产转移验证信息中的第二签名数据验证通过，则确定对资产转移验证信息验证通过，将第二持有码发送给第二客户端，以表征待转移资产归属于第二用户。
具体的，根据资产转移验证信息中的第一标识信息，从区块链中获取关联保存的第一持有码；根据获取的第二公钥对资产转移验证信息中的第二签名数据进行验签处理得到第一持有码；将获取的第一持有码与得到的第一持有码进行匹配；若匹配成功，则将第二持有码发送给第二客户端；若匹配失败，则向第二客户端发送资产获取失败信息。
至此，基于对第一签名数据以及第二签名数据的验证，实现了待转移资产的有效转移。为了解除待转移资产的锁定状态，以及便于后续对资产的转移过程进行追溯，如图8所示，步骤S108之后，还包括：步骤S110，根据资产转移信息，生成资产转移成功记录信息，将资产转移成功记录信息保存至区块链中。
具体的，将资产转移信息中的待转移资产的第一标识信息、第一用户的用户信息、资产转移确认信息包括的第二用户的用户信息等关联记录，将记录的信息确定为资产转移成功记录信息，该资产转移成功记录信息表征待转移资产处于未锁定状态。
进一步的，为了使第一用户知晓资源转移结果，步骤S108之后还包括：向第一客户端发送资源转移结果信息。

需要说明的是，本说明书中关于存储介质的实施例与本说明书中关于资产转移方法的实施例基于同一发明构思，因此该实施例的具体实施可参见前述对应的资产转移方法的实施，重复之处不再赘述。
上述对本说明书特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下，在权利要求书中记载的动作或步骤可按照不同于实施例中的顺序来执行并且仍然可实现期望的结果。另外，在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序才能实现期望的结果。在某些实施方式中，多任务处理和并行处理也是可的或者可能是有利的。
在20世纪90年代，对于一个技术的改进可很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device，PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来 撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可很容易得到实现该逻辑方法流程的硬件电路。
控制器可按任何适当的方式实现，例如，控制器可采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可视为硬件部件内的结构。或者甚至，可将用于实现各种功能的装置视为既可是实现方法的软件模块又可是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元，具体可由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
为了描述的方便，描述以上装置时以功能分为各种单元分别描述。当然，在实施本说明书实施例时可把各单元的功能在同一个或多个软件和/或硬件中实现。
本领域内的技术人员应明白，本说明书一个或多个实施例可提供为方法、系统或计算机程序产品。因此，本说明书一个或多个实施例可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本说明书可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本说明书是参照根据本说明书实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括 指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中，计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(RAM)和/或非易失性内存等形式，如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可由任何方法或技术来实现信息存储。信息可是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括，但不限于相变内存(PRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(CD-ROM)、数字多功能光盘(DVD)或其他光学存储、磁盒式磁带，磁带磁磁盘存储或其他磁性存储设备或任何其他非传输介质，可用于存储可被计算设备访问的信息。按照本文中的界定，计算机可读介质不包括暂存电脑可读媒体(transitory media)，如调制的数据信号和载波。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
本说明书一个或多个实施例可在由计算机执行的计算机可执行指令的一般上下文中描述，例如程序模块。一般地，程序模块包括执行特定任务或实现特定抽象数据类型的例程、程序、对象、组件、数据结构等等。也可在分布式计算环境中实践本说明书的一个或多个实施例，在这些分布式计算环境中，由通过通信网络而被连接的远程处理设备来执行任务。在分布式计算环境中，程序模块可位于包括存储设备在内的本地和远程计算机存储介质中。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上所述仅为本文件的实施例而已，并不用于限制本文件。对于本领域技术人员来说，本文件可有各种更改和变化。凡在本文件的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本文件的权利要求范围之内。
