具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
下面参照附图1和2描述根据本申请第一方面实施例的分布式数字凭证处理方法。
图1是根据本申请的一个实施例的分布式数字凭证处理方法的流程图，如图1所述，本申请实施例的分布式数字凭证处理方法包括步骤S1、步骤S2和步骤S3。在实施例中，该方法可以用在网关，通过网关来实现。
步骤S1，轮询数字凭证处理节点，获得最新的数字凭证处理任务模板数据。
在本申请实施例中，在数字凭证处理服务设备与数字凭证处理节点之间增加网关，例如，网关分别连接数字凭证处理节点和多个数字凭证处理服务设备，通过网关轮询数字凭证处理节点，获得数字凭证处理任务模板数据。
在实施例中，数字凭证处理任务模板数据可以包括任务内容、难度信息、数据量大的交易数据以及其他相关数据，其中，大量数据是数字凭证处理设备的数字凭证处理任务所不需要的数据例如交易数据。
具体地，网关轮询数字凭证处理节点，获得数字凭证处理任务模板数据后，验证是否是最新的数字凭证处理任务模版数据，例如可以根据获取时间的先后或者该数据缓存时间的先后。
步骤S2，根据数字凭证处理任务模板数据生成数字凭证处理任务的精简任务模板数据。
在实施例中，精简任务模板数据可以包括数字凭证处理任务所需要的数据例如任务内容和难度信息，去除了一些不需要的数据例如数据量大的交易数据，此类交易数据可以缓存在网关中。通过去除数字凭证处理任务模板数据中对于数字凭证处理任务不需要的数据来获得精简任务模板数据。
步骤S3，将精简任务模板数据分发给数字凭证处理服务设备。
具体地，在数字凭证处理节点和多个数字凭证处理服务设备之间增加一个网关，通过网关轮询数字凭证处理节点获得数字凭证处理模板数据，并将数字凭证处理模板数据中数据量大、数字凭证处理不需要的数据去除，获得精简任务模板数据，即只下发传输数字凭证处理需要的数据给数字凭证处理服务设备，进而数字凭证处理服务设备根据精简任务模板数据后生成数字凭证处理任务，并将数字凭证处理任务分发给数字凭证处理设备。
相当于将数字凭证处理服务分成两个部分，其中一个部分由网关来获得精简任务模板数据，另一个部分由数字凭证处理服务设备生成数字凭证处理任务并分发给数字凭证处理设备，多个数字凭证处理服务设备无需分别轮询数字凭证处理节点，主要的网络通 信模式从轮询模式转换为通知模式。
在一些实施例中，数字凭证处理设备进行与数字凭证相关的数据处理，通过数据处理可以得到数字凭证，进一步地，当数字凭证与加密货币相关或体现为加密货币时，本申请实施例的数字凭证处理设备可以是区块链计算设备，数字凭证可以是以区块链技术为基础的加密货币。
根据本申请实施例的分布式数字凭证处理方法，通过网关轮询数字凭证处理节点，相较于相关技术中多个数字凭证处理服务设备分别频繁从数字凭证处理节点读取大量数据，可以减小数字凭证处理节点和数字凭证处理服务设备的计算负载和网络负载，并且，将数字凭证处理任务模板数据转换为精简任务模板数据，数字凭证处理任务所不需要的数据尤其包括数据量大的交易数据可以缓存在网关中，将精简任务模板数据分发给数字凭证处理服务设备，从而可以降低通信负载，缩短获取最新任务模板数据的时间，以及减小网络传输数据量，降低数据延迟。
进一步地，在一些实施例中，生成数字凭证处理任务的精简任务模板数据的过程可以包括：从数字凭证处理任务模板数据中提取数字凭证处理任务数据所需的字段例如版本、ntime、上一个块的hash值、nbits、以及任务列表；根据任务列表构建数字凭证交易数据的merkle树；计算merkle树的左树hash列表；生成块初始数字凭证交易例如Coinbase交易；根据以上数据生成精简任务模板数据，其中，以上数据包括左树hash列表和块初始数字凭证交易，还可以包括上一个块的hash值、nbits、版本等信息，并将精简任务模板数据下发给数字凭证处理服务设备，即将数据量较大的交易数据缓存在网关中，只下发交易哈希的merkle树的左树，可以使得数据量从数字凭证处理服务数乘以几兆、几十兆字节降低到几千字节，大大降低通信负载，缩短获取最新数字凭证处理任务的时间。
举例说明，图2是根据本申请的一个实施例的分布式数字凭证处理系统的示意图，如图2所示，将数字凭证处理服务分成了两部分，包括数字凭证处理服务设备和网关，网关与数字凭证处理节点连接，数字凭证处理节点连接数字凭证网络，数字凭证处理服务设备分别连接多个数字凭证处理设备。其中，网关负责轮询数字凭证处理节点的RPC(Remote Procedure Call，远程过程调用)服务，以获取最新的数字凭证处理任务模板数据，并将数字凭证处理任务模板数据中对于数字凭证处理任务所不需要的数据例如数据量大的交易数据，生成精简任务模板数据，并主动分发给与其连接的所有数字凭证处理服务设备。数字凭证处理服务设备基于接收到的精简任务模板数据，经过处理补充其 他数据后生成数字凭证处理任务，并将数字凭证处理任务分发给数字凭证处理设备，其中，补充其他数据可以包括例如矿池的水印、节点的标示等信息，水印可以用来标识该数据块是该矿池处理的。
在一些实施例中，网关和数字凭证处理服务设备之间可以通过注册机制来建立连接。具体地，每个网关有自己的网关身份识别码，并给每个数字凭证处理服务设备分配一个服务身份识别码，在建立连接时，网关获取数字凭证处理服务设备的注册信息，并识别该注册信息是否有效，在有效时，根据注册信息与数字凭证处理服务设备建立连接。其中，两者在第一次连接时，可以通过注册信息来建立连接，以后不需要，除非连接断开，需要重新连接。
在实施例中，本申请实施例的分布式数字凭证处理方法还包括提交报块流程，网关接收到精简报块信息生成块数据，并将块数据提交至数字凭证处理节点。其中，由于交易数据存储在网关，精简报块信息不包含交易数据，从而可以减小传输数据量，提高传输效率。
具体地，如图2所示，数字凭证处理设备接收到数字凭证处理任务后，根据数字凭证处理任务进行计算，在获得数字凭证处理任务的答案时，提交贡献份额(share)给数字凭证处理服务设备，数字凭证处理服务设备对share信息进行验证，如果满足数字凭证处理任务的难度，则推算对应的数字凭证处理设备的工作量，如果基于该share信息构建的区块头满足报块标准，则数字凭证处理服务设备提交精简报块信息给网关，精简报块信息可以包括区块头信息，网关接收到精简报块信息后，获取精简报块信息中的区块头信息，根据区块头信息补充交易数据，交易数据在生成数字凭证处理任务流程中已经缓存在网关中，网关将区块头信息和交易数据进行组装，并将区块头信息和交易数据的组装信息提交至数字凭证处理节点，通过数字凭证处理节点的RPC服务进行报块。
总的来说，本申请实施例的分布式数字凭证处理方法，把大量网络数据通信的过程单独分离出来，由网关来处理，把数据量大、数字凭证处理任务不需要的数据不下发和传输，只下发和传输数字凭证处理任务需要的数据，从而，可以减小数字凭证处理节点和数字凭证处理服务设备的计算负载和网络负载，减小数据传输的延迟性，缩短获得最新数字凭证处理任务的时间。
对于服务数字凭证处理设备数量多，部署的数字凭证处理服务设备数量多的分布式大型数字凭证处理系统，采用本申请的分布式数字凭证处理方法，效果更加明显。

在实施例中，如图5所示，本申请实施例的网关10还包括报块模块5，报块模块5配置为响应于精简报块信息生成块数据，将该块数据提交至数字凭证处理节点，其中，精简报块信息不包括交易数据，从而可以减小传输数据量，提高数据传输效率。
具体地，如图2所示，数字凭证处理设备接收到数字凭证处理任务后，根据数字凭证处理任务进行计算，在获得数字凭证处理任务的答案时，提交份额(share)给数字凭证处理服务设备，数字凭证处理服务设备对基于该share信息构建的区块头进行验证，如果满足数字凭证处理任务的难度，则推算对应的数字凭证处理设备的工作量，如果基于该share信息构建的区块头满足报块标准，则数字凭证处理服务设备提交精简报块信息给网关10。精简报块信息可以包括区块头信息，如图6所示，报块模块5进一步包括获取单元51、补充单元52和提交单元53。其中，获取单元51配置为获取精简报块信息中的区块头信息；补充单元52配置为根据区块头信息补充交易数据，其中，交易数据在生成数字凭证处理任务流程中已经缓存在网关10中，补充单元52将区块头信息和交易数据进行组装；提交单元53配置为将区块头信息和交易数据的组装信息提交至数字凭证处理节点，通过数字凭证处理节点的RPC服务进行报块。

本申请中使用的用词仅用于描述实施例并且不用于限制权利要求。如在实施例以及权利要求的描述中使用的，除非上下文清楚地表明，否则单数形式的“一个”(a)、“一个”(an)和“所述”(the)旨在同样包括复数形式。类似地，如在本申请中所使用的术语“和/或”是指包含一个或一个以上相关联的列出的任何以及所有可能的组合。另外，当用于本申请中时，术语“包括”(comprise)及其变型“包括”(comprises)和/或包括(comprising)等指陈述的特征、整体、步骤、操作、元素，和/或组件的存在，但不排除一个或一个以上其它特征、整体、步骤、操作、元素、组件和/或这些的分组的存在或添加。
所描述的实施例中的各方面、实施方式、实现或特征能够单独使用或以任意组合的方式使用。所描述的实施例中的各方面可由软件、硬件或软硬件的结合实现。所描述的实施例也可以由存储有计算机可读代码的计算机可读介质体现，该计算机可读代码包括可由至少一个计算装置执行的指令。所述计算机可读介质可与任何能够存储数据的数据存储装置相关联，该数据可由计算机系统读取。用于举例的计算机可读介质可以包括只读存储器、随机存取存储器、CD-ROM、HDD、DVD、磁带以及光数据存储装置等。所述计算机可读介质还可以分布于通过网络联接的计算机系统中，这样计算机可读代码就可以分布式存储并执行。
上述技术描述可参照附图，这些附图形成了本申请的一部分，并且通过描述在附图中示出了依照所描述的实施例的实施方式。虽然这些实施例描述的足够详细以使本领域技术人员能够实现这些实施例，但这些实施例是非限制性的；这样就可以使用其它的实施例，并且在不脱离所描述的实施例的范围的情况下还可以做出变化。比如，流程图中所描述的操作顺序是非限制性的，因此在流程图中阐释并且根据流程图描述的两个或两个以上操作的顺序可以根据若干实施例进行改变。作为另一个例子，在若干实施例中，在流程图中阐释并且根据流程图描述的一个或一个以上操作是可选的，或是可删除的。另外，某些步骤或功能可以添加到所公开的实施例中，或两个以上的步骤顺序被置换。所有这些变化被认为包含在所公开的实施例以及权利要求中。
另外，上述技术描述中使用术语以提供所描述的实施例的透彻理解。然而，并不需要过于详细的细节以实现所描述的实施例。因此，实施例的上述描述是为了阐释和描述而呈现的。上述描述中所呈现的实施例以及根据这些实施例所公开的例子是单独提供的，以添加上下文并有助于理解所描述的实施例。上述说明书不用于做到无遗漏或将所描述的实施例限制到本申请的精确形式。根据上述教导，若干修改、选择适用以及变化 是可行的。在某些情况下，没有详细描述为人所熟知的处理步骤以避免不必要地影响所描述的实施例。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
