具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书一个或多个实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本说明书一个或多个实施例的一些方面相一致的装置和方法的例子。
需要说明的是：在其他实施例中并不一定按照本说明书示出和描述的顺序来执行相应方法的步骤。在一些其他实施例中，其方法所包括的步骤可以比本说明书所描述的更多或更少。此外，本说明书中所描述的单个步骤，在其他实施例中可能被分解为多个步骤进行描述；而本说明书中所描述的多个步骤，在其他实施例中也可能被合并为单个步骤进行描述。
互联网上的业务平台作为面向用户的平台，可对接多家业务提供方以为多家业务提供方的业务处理提供用户业务受理、及业务处理结果通知服务。业务平台和业务提供方在合作过程中，需要进行业务数据双向同步，为此出现最大的问题是数据单向流动，接收方的接收情况，发送方无法感知，进而造成数据不一致的情况。目前很多业务平台和业务提供方终端使用的数据核对方案，都是基于双方的数据库的日结文件进行核对(例如总督核对)，当出现数据缺失时，没有快速的发现定位机制；同时数据的同步核对过程缺乏足够的信任凭证。
有鉴于此，在本说明书示出的一种实施方式中，提供了一种基于区块链的数据处理方法，应用于包括业务平台方节点设备和业务提供方节点设备的区块链网络***；所述业务平台方节点设备与所述业务提供方节点设备通信连接以进行数据传输。
本说明书一个或多个实施例所述的区块链网络，具体可指一个各节点设备通过共识机制达成的、具有分布式数据存储结构的P2P网络***，该区块链内的数据分布在时间上相连的一个个“区块(block)”之内，后一区块包含前一区块的数据摘要，且根据具体的共识机制(如POW、POS、DPOS或PBFT等)的不同，达成全部或部分节点的数据全备份。本领域的技术人员熟知，由于区块链网络***在相应共识机制下运行，已收录至区块链数据库内的数据很难被任意的节点篡改，例如采用Pow共识的区块链，至少需要全网51％算力的攻击才有可能篡改已有数据，因此区块链***有着其他中心化数据库***所无法比拟的保证数据安全、防攻击篡改的特性。由此可知，被收录至区块链的分布式数据库中的数据不会被攻击或篡改，从而保证了存证入区块链的分布式数据库的数据信息的真实可靠性。
区块链网络的示例类型可以包括公有区块链网络、私有区块链网络和联盟区块链网络。尽管术语区块链通常与比特币加密货币网络相关联，但是本文使用的区块链可指代不参考任何特定用例的DLS(分布式账本***)。
在公有区块链网络中，共识过程由共识网络的节点控制。例如，数百、数千、甚至数百万个实体可以在公有区块链网络中协作，每个实体在公有区块链网络中操作至少一个节点。因此，公有区块链网络可以被认为是相对于参与实体的公有网络。示例公有区块链网络包括比特币网络，比特币网络是对等支付网络。比特币网络利用分布式账本，被称为区块链。然而如上所述，术语区块链通常用于指代不特别参考比特币网络的分布式账本。
通常，公有区块链网络支持公有交易。公有交易与公有区块链网络内的所有节点共 享，并存储在全局区块链中。全局区块链是跨所有节点复制的区块链。也就是说，对于全局区块链，所有节点处于完全一致的状态。为了达成共识(例如，同意向区块链添加块)，在公有区块链网络内实施共识协议。示例共识协议包括但不限于，在比特币网络中实施的工作量证明(proof-of-work，POW)。
通常，私有区块链网络提供给特定实体，特定实体集中控制读取和写入权限。该实体控制哪些节点能够参与区块链网络。因此，私有区块链网络通常被称为许可网络，其对允许谁参与网络及其参与水平(例如，仅在某些交易中)施加限制。可以使用各种类型的访问控制机制(例如，现有参与者投票添加新实体，监管机构可以控制准入)。
通常，联盟区块链网络在参与实体中是私有的。在联盟区块链网络中，共识过程由授权的一组节点(联盟成员节点)控制，一个或多个节点由相应的实体(例如，企业)操作。例如，由十(10)个实体(例如，企业)组成的联盟可以操作联盟区块链网络，每个实体在该联盟区块链网络中操作至少一个节点。因此，就参与实体而言，联盟区块链网络可以被认为是私有网络。在一些示例中，每个实体(节点)必须对每个块进行签名，以使该块有效并将有效的块添加到区块链。在一些示例中，至少实体(节点)的子集(例如，至少7个实体)必须对每个块进行签名以使该块有效，并且将有效的块添加到区块链。
可以预期，本说明书所提供的实施方式能够在任何合适类型的区块链网络中实现。
本说明书一个或多个实施例所述的节点(或节点设备)是指可通过遵循相应节点协议、运行节点协议程序的安装来加入该区块链，作为该区块链的节点。本领域的技术人员通常将具有区块链分布式数据库的数据全备份的节点设备称为全节点，将具有区块链分布式数据库的部分备份数据(如仅有区块头的数据)的节点设备称为轻节点等。在本说明书的一个或多个实施例中，并不限定上述业务平台方节点设备或业务提供方节点设备的节点类型；也并不限定上述业务平台方节点设备或业务提供方节点设备的个数，上述业务平台方或业务提供方可以对应一个设备终端或服务器，也可以对应多个设备终端或服务器以作为上述区块链的节点设备。
本说明书一个或多个实施方式所述的业务平台方是指网络业务平台对应的实体方，业务提供方是对业务平台受理的业务进行处理的实体方。业务平台可以是为业务提供方运营的业务提供面向用户的服务，上述服务可包括接收用户的业务受理、向用户提供业务处理结果等；因此，业务平台方可以与一个或多个业务提供方终端对接，向一个或多个业务提供方终端发送业务受理数据，并从一个或多个业务提供方接收经其处理所得的 业务处理数据。
如图1所示，本实施方式所提供的基于区块链的数据处理方法，包括：
步骤102，所述业务平台方节点设备生成目标业务对象的业务受理数据，所述业务受理数据包括所述目标业务对象的标识。
业务平台方节点设备可根据其自身设定的业务处理流程，基于用户的业务申请，而生成目标业务对象的业务受理数据；本说明书并不限定上述业务对象或目标业务对象的内容和形式，可根据上述业务平台方所运营的具体业务类型而定。例如，当上述业务平台方运营电子商务业务时，上述业务对象或目标业务对象可以为交易的商品或服务；当上述业务平台方运营家政维修等人力服务业务时，上述业务对象或目标业务对象可以为提供人力服务的个人；当上述业务平台方运营资产托管业务时，上述业务对象或目标业务对象可以为用户托管的资产；当上述业务平台方运营投保业务时，上述业务对象或目标业务对象可以为用户投保的保单，等等。
相应地，该业务平台方节点设备基于目标业务对象的性质，可自主生成目标业务对象的标识，或选用目标业务对象的某项属性作为目标业务对象的标识；例如，在上述列举的实例中，上述业务受理数据中的目标业务对象的标识可包括：电商订单编号、或服务人员身份标识号码、或托管的资产属性编码、或保单编号等等，在此不做限定。
步骤104，所述业务平台方节点设备向所述区块链发送第一交易，所述第一交易基于所述业务受理数据生成；所述第一交易包括目标业务对象的标识。
本说明书中一个或多个实施方式中所描述的交易(transaction)，是指通过区块链的节点设备创建，并需要最终发布至区块链的区块中的一笔数据。其中，区块链中的交易，存在狭义的交易以及广义的交易之分。狭义的交易是指用户向区块链发布的一笔价值转移；例如，在传统的比特币区块链网络中，交易可以是用户在区块链中发起的一笔转账。而广义的交易是指用户实体通过节点向区块链发布的一笔具有业务意图的业务数据。本实施方式所述的第一交易，是基于所述业务受理数据生成的其包括上述目标业务对象的标识的一笔数据；在一种具体的实施方式中，上述第一交易可包括上述业务受理数据的全部内容，在又一种具体的实施方式中，上述第一交易可包括上述业务受理数据的哈希摘要和目标业务对象的标识；基于区块链的防篡改机制，起到为上述业务受理数据和目标业务对象的标识存证的作用。
将上述实施例所述的第一交易收录到所述区块链的区块中的详细过程，可依据所述 区块链的验证机制、共识机制而具体设定。在一示出的实施例中，所述将第一交易上传到所述区块链的分布式数据库中，包括:
所述区块链中具有记账权限的节点在验证所述第一交易通过后，将所述第一交易加入到候选区块；
从所述具有记账权限的节点中确定满足所述区块链共识机制的共识记账节点；
所述共识记账节点向所述区块链的节点广播所述候选区块；
在所述候选区块通过所述区块链符合预设数量的节点的验证认可后，所述候选区块被视为最新区块，加入到所述区块链的分布式数据库中。
在上述的实施例中，具有记账权限的节点是指具有生成候选区块权限的节点。根据所述区块链的共识机制，可从上述对所述候选区块具有记账权限的节点中确定共识记账节点，上述共识机制可以包括工作量证明机制(PoW)、或权利证明机制(PoS)、或股份授权证明机制(DPoS)、或联盟链常用的拜占庭容错算法机制(PBFT)等。
在实际的业务应用中，本说明书上述一个或多个实施例所述的区块链网络可以构架为联盟链，上述业务平台方节点设备作为联盟成员节点设备，向联盟链上发送上述第一交易。相比于公有链，联盟链采用的共识算法通常效率高，可满足高频交易量的需求，例如基于大量业务受理需求而频繁产生的第一交易；且共识的时延很低，基本达到实时处理的要求，能快速实时地在区块链的新生区块中收录上述第一交易；而且，将联盟链网络中可信节点(如业务平台方或业务提供方对应的节点)作为预选的记账节点，兼顾了安全性与稳定性；另外，联盟链的共识算法(如PBFT)通常不会消耗过多的计算机算力资源，也不一定需要代币流通，因此具有良好的可使用性。
步骤106，上述业务提供方节点设备从所述区块链的区块获取所述第一交易。
上述业务提供方节点设备可为上述第一交易设置事件监听机制，在同步到存储有上述第一交易的区块时，获取到所述第一交易被收录至所述区块链的区块的事件通知，从而从本地已同步的区块链区块中获取到上述第一交易。当然，上述业务提供方节点设备也可基于目标业务对象的标识，在区块链的区块数据中检索查询，以获取上述第一交易。
步骤108，所述业务提供方节点设备核对是否已接收到所述业务平台方节点设备发送的、与所述第一交易对应的所述业务受理数据。
在本实施方式中，上述业务平台方节点设备与业务提供方节点设备通信连接，上述 业务平台方节点设备可直接向上述业务提供方节点设备发送所述业务受理数据，以使上述业务提供方节点设备接收上述业务受理数据；但是由于网络***拥堵或故障等原因，上述业务提供方节点设备也可能在获取到上述第一交易时还未接到收到业务平台方发送的业务受理数据。
如果否，步骤110，所述业务提供方节点设备执行预设的业务受理数据获取逻辑。
本实施方式并不限定上述预设的业务受理数据获取逻辑的具体执行方式，业务提供方节点设备可向所述业务平台方节点设备发送所述业务受理数据的获取申请，以提示上述业务平台方节点设备发送或者再次发送上述业务受理数据；在又一实现方式中，当上述第一交易包括上述业务受理数据的全部内容时，上述业务提供方节点设备可以基于从区块链网络同步的区块中获取到的上述第一交易，生成所述业务受理数据的内容。
如果是，步骤112，所述业务提供方节点设备基于所述业务受理数据，执行对所述目标业务对象的业务处理逻辑，以生成所述目标业务对象的业务处理数据，所述业务处理数据包括所述目标业务对象的标识和所述目标业务对象的至少一个属性数据。
上述业务提供方节点设备基于自身设置的业务处理逻辑规则，对目标业务对象进行业务处理，以生成上述目标业务对象的业务处理数据；上述至少一个属性数据可用于描述上述目标业务对象的处理结果，如在上述列举的各种业务对象实例中，业务对象的属性数据可以为“已发货”、或“已接单”、或“已托管”或“已批保”等等；在又一示出的实施方式中，上述至少一个属性数据还可以为上述目标业务对象的业务处理数据的哈希摘要。
步骤114，所述业务提供方节点设备向所述区块链网络发送第二交易；所述第二交易基于所述业务处理数据生成，且包括所述目标业务对象的标识和所述至少一个属性数据。
与上述第一交易类似，本实施方式所述的第二交易，是基于所述业务处理数据生成的其包括上述目标业务对象的标识和所述目标业务对象的至少一个属性数据的一笔数据；在一种具体的实施方式中，上述第二交易可包括上述业务处理数据的全部内容，在又一种具体的实施方式中，上述第二交易可包括上述业务处理数据的哈希摘要、上述目标业务对象的标识和至少一个属性数据；基于区块链的防篡改机制，起到为上述业务处理数据和目标业务对象的标识存证和至少一个属性数据的作用。
将上述第二交易收录至区块链区块的具体过程可与上述第一交易被收录的具体实施 过程类似，在此不再赘述。
步骤116，所述业务平台方节点设备从所述区块链的区块获取所述第二交易。
类似地，上述业务平台方节点设备可为上述第二交易设置事件监听机制，在同步到存储有上述第二交易的区块时，获取到所述第二交易被收录至所述区块链的区块的事件通知，从而从本地已同步的区块链区块中获取到上述第一交易。当然，上述业务平台方节点设备也可基于目标业务对象的标识，在区块链的区块数据中检索查询，以获取上述第二交易。
步骤118，所述业务平台方节点设备核对是否已接收到所述业务提供方节点设备发送的、与所述第二交易对应的所述业务处理数据。
在本实施方式中，上述业务平台方节点设备与业务提供方节点设备通信连接，上述业务提供方节点设备可直接向上述业务平台方节点设备发送所述业务处理数据，以使上述业务平台方节点设备接收到上述业务处理数据；但是由于网络***拥堵或故障等原因，上述业务平台方节点设备也可能在获取到上述第二交易时还未接到收到业务提供方发送的业务受理数据。
如果否，步骤120，所述业务平台方节点设备执行预设的业务处理数据获取逻辑。
类似地，本实施方式并不限定上述预设的业务处理数据获取逻辑的具体执行方式，业务平台方节点设备可向所述业务提供方节点设备发送所述业务处理数据的获取申请，以提示上述业务提供方节点设备发送或者再次发送上述业务处理数据；在又一实现方式中，当上述第二交易包括上述业务处理数据的全部内容时，上述业务平台方节点设备可以基于从区块链网络同步的区块中获取到的上述第二交易，生成所述业务处理数据的内容。
如果是，步骤122，所述业务平台方节点设备执行对所述业务处理数据的应用逻辑。
本实施方式并不限定对业务处理数据的应用逻辑的具体执行内容和方式，上述业务平台方节点设备可基于业务平台的具体业务应用场景而执行包含业务处理结果的业务处理数据的应用，如向平台用户推送业务处理结果，或执行下一流程的业务动作，等等。
基于上述一个或多个实施方式提供的基于区块链的数据处理方法，在区块链的分布式数据库(区块)中为目标业务对象的业务受理数据和业务处理数据进行相应的区块链存证，基于区块链的防篡改机制，在区块链的区块账本中基于目标业务对象标识，为目标业务对象的业务受理和处理流程建立了完整且不可篡改的数据追溯链路，方便业务平 台方和业务提供方基于该数据追溯链路进行业务数据的核对和补全，提高了数据核对的效率。
为了进一步方便上述业务平台方和业务提供方的数据核对，当所述业务平台方节点设备与所述业务提供方节点设备通信连接以进行上述业务受理数据和业务处理数据的传输时，在又一示出的实施方式中，所述业务平台方节点设备和所述业务提供方节点设备均基于从区块上获取的第一交易和第二交易生成有所述目标业务对象的交易流水记录；所述交易流水记录包括所述目标业务对象的标识、所述第一交易和第二交易的交易标识。第一交易的交易标识可以包括业务受理数据的哈希值、或上述第一交易的哈希值(TxID)，等等；第二交易的交易标识可包括业务处理数据的哈希值、或上述第二交易的哈希值(TxID)，等等。
相应地，上述实施方式所述的所述业务提供方节点设备核对是否已接收到所述业务平台方节点设备发送的、与所述第一交易对应的所述业务受理数据，包括：所述业务提供方节点设备基于所述交易流水记录包括的第一交易的交易标识，核对是否已接收到所述业务平台方节点设备发送的所述业务受理数据。上述实施方式所述的所述业务平台方节点设备核对是否已接收到所述业务提供方节点设备发送的、与所述第二交易对应的所述业务处理数据，包括：所述业务平台方节点设备基于所述交易流水记录包括的第二交易的交易标识，核对是否已接收到所述业务提供方节点设备发送的所述业务处理数据。
上述业务平台方和业务提供方节点设备可基于区块链数据生成的交易流水记录核对各自接收的业务数据，当各自接收的业务数据与链上交易流水记录一致时，即可保证双方传输的业务数据记录一致，无业务数据遗漏或掉包。而且基于交易流水记录进行业务数据核对，无需等待以进行日结核对，可随时展开，提高了业务数据核对的效率；由于现有的核对***开发联调成本较大，且需要双方配合进行，而基于区块链开展的数据核对，无需进一步开发部署双方的核对联调，降低了业务数据核对的成本；而且，基于区块链数据开展的数据核对，得益于区块链数据不易被篡改的属性，更加提高了业务数据核对的可信程度。
经过上述高效且可信的数据核对，双方可通过再次通信发送数据获取申请，及时地补全在双方数据传输中遗漏或掉包的业务数据，或者，双方可基于区块链上的第一交易或第二交易，补全在双方数据传输中遗漏或掉包的业务数据，从而进一步提高了双方***业务处理的效率。本领域的技术人员应知，基于区块链区块上存储的第一交易或 第二交易进行业务数据补全，不仅省去了双方再次联调的成本，而且基于区块链的防篡改机制，更提高了其补全的业务数据的可信程度。
值得注意的是，区块链的分布式数据库除了包括区块链的区块“账本”，还可包括基于区块“账本”上的交易而生成的、分布在区块链的节点设备本地的“世界状态(world state)”数据库；基于区块内的交易生成相应数据对象的世界状态的具体方式，一般通过区块内的交易调用智能合约来执行，在此不再赘述。
因此在本说明书又一示出的实施方式中，上述第一交易用以在被收录至所述区块链的区块后，由所述区块链的节点设备基于所述第一交易在所述区块链的世界状态数据库建立目标业务对象对应的数据集合，所述数据集合包括所述目标业务对象的标识；所述第二交易用以在被收录至所述区块链的区块后，由所述区块链的节点设备基于所述第二交易在所述区块链的世界状态数据库更新目标业务对象对应的数据集合，所述更新后的数据集合包括所述目标业务对象的标识和所述至少一个属性数据。
因此在本实施方式中，上述业务平台方节点设备除了基于所述第二交易，还可在第二交易被收录到区块后，基于区块链世界状态数据库中存储的所述目标业务对象对应的数据集合生成所述业务处理数据；上述业务提供方节点设备除了基于所述第一交易，还可在第一交易被收录到区块后，基于区块链世界状态数据库中存储的基于所述目标业务对象对应的数据集合生成所述业务处理数据。
业务平台方节点设备或业务提供方节点设备可在本地数据库中直接查询目标业务对象的标识或目标业务对象的属性数据，从而直接获取到相应的业务受理数据或业务处理数据。

如果是，步骤213，保险平台方基于上述保单核保结果数据/所述保险批改单批改结果数据向保险平台用户推送核保结果/批改结果通知。
如果否，步骤214，保险平台方节点设备基于本地的世界状态数据库中存储的已基于第二交易更新的保单/批改单对应的数据集合，生成相应的保单核保结果数据/所述保险批改单批改结果数据。
如前所述，区块链网络***可基于上述第一交易和第二交易为上述保单/批改单设置相应的世界状态数据集合；图4(a)(b)分别示意了在上述区块链的世界状态数据库中存储的保单和批改单对应的数据集合结构；上述保险机构方和保险平台方节点设备可基于设备本地数据库中存储的如图4(a)(b)示意的保单/批改单状态数据中，补全其保单/批改单受理数据和保单核保结果数据/所述保险批改单批改结果数据。相对于通过区块链交易获取上述保单/批改单的状态或相应业务数据，通过在区块链的世界状态数据库中建立保单/批改单状态数据，可以更加方便快捷地获取到上述保单/批改单的状态或相应业务数据。
