实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术对象在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了更好地理解本申请实施例的方案，下面先对本申请实施例可能涉及的一些基本概念进行介绍。
(1)区块链：区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。它本质上是一个去中心化的数据库，是一串使用密码学方法相关联产生的数据块，每一个数据块中包含了一批次网络交易的信息，用于验证其信息的有效性(防伪)和生成下一个区块。狭义来讲，区块链是一种按照时间顺序将数据区块以顺序相连的方式组合成的一种链式数据结构，并以密码学方式保证的不可篡改和不可伪造的分布式账本，广义来讲，区块链技术是利用块链式数据结构来验证与存储数据、利用分布式节点共识算法来生成和更新数据、利用密码学的方式保证数据传输和访问的安全、利用由自动化脚本代码组成的智能合约来编程和操作数据的一种全新的分布式基础架构与计算方式。
(2)智能合约：计算机化的协议，可以执行某个合约的条款，通过部署在共享账本上的用于在满足一定条件时而执行的代码实现，根据实际的业务需求代码用于完成自动化的交易(也叫“资源交换”)，例如查询买家所购买商品的物流状态，在买家签收货物后将买家的数字资产转移到商户 的地址；当然，智能合约不仅限于执行用于交易的合约，还可以执行对接收的信息进行处理的合约。
(3)非同质化权益证明凭证：是在区块链技术基础上衍生出一种的内含若干规则与信息的具有不可复制、不可分割的唯一性数字加密权益证明，用来表明某个数字物品的权益归属。
本申请实施例提供了一种基于区块链的数据处理方法、相关装置及介质和程序产品，可以缓解区块链网络中主链节点的存储压力，同时有效避免相同资源交换被重复执行，解决资源交换双花问题。其中，双花又叫双重支出，是指同一资源同时支付给两个接收者。
请参见图1，是本申请实施例提供的一种区块链结构示意图。
如图1所示，区块链101由多个区块组成，区块链的第一个区块称为创世区块(可简称为创世快)，创世块中包括区块头和区块体，区块头中存储有输入信息特征值、版本号、时间戳和难度值，区块体中存储有输入信息；创世块的下一区块以创世块为父区块，下一区块中同样包括区块头和区块体，区块头中存储有当前区块的输入信息特征值、父区块的区块头特征值、版本号、时间戳和难度值，并以此类推，使得区块链中每个区块中存储的区块数据均与父区块中存储的区块数据存在关联，保证了区块中输入信息的安全性。
进一步的，区块链网络可以由各个区块链节点进行维护，可以将区块链网络理解为一个用于区块链节点与区块链节点之间进行数据共享的数据共享系统，该数据共享系统的一种示例性结构可参见图2；图2所示，数据共享系统中可包括多个区块链节点102，各个区块链节点102可以为接入至该区块链网络中的服务器，也可以为接入至该区块链网络中的终端设备(如客户端)，这里对区块链节点102的具体形式不做限定。对于区块链网络中的每个区块链节点102，均具有与其对应的节点标识，而且区块链网络中的每个区块链节点102均可以存储有区块链网络中其它区块链节点102的节点标识，以便后续根据其它区块链节点102的节点标识，将生成的区块广播至数据共享系统中的其它区块链节点102。每个区块链节点102中可维护一个节点标识列表，将节点名称和节点标识对应存储至节点标识列表中；其中，节点标识列表可参见表1：
表1
如表1所示，节点标识可为IP(Internet Protocol，网络之间互联的协议)地址以及其它任一种能够用于标识该节点的信息；例如，节点标识还可以是二进制序列码(如110001110)，表1中仅以IP地址为例进行说明。当区块链网络中产生待验证区块时，区块链网络中运行共识机制的区块链节点(或称为共识节点)对该待验证区块进行共识，并在共识成功后通过节点标识列表中的节点标识，将该待验证区块同步至区块链网络中的各个区块链节点，实现在区块链网络中对数据的分布式存储。
基于上述描述，本申请实施例提供了基于区块链的数据处理方法所适用的基于区块链的数据处理系统，请参见图3，为本申请实施例提供的一种基于区块链的数据处理系统的架构图。如图3所示，区块链网络103中维护有业务主链104和业务子链105，业务主链104中包括主链节点1041，业务子链105中包括子链节点1051，主链节点1041与子链节点1051之间可以通过通信网络实现彼此之间的数据传输。
在本申请实施例中，子链节点1051可以从业务子链105对应的资源交换池中获取待处理资源交换集合，然后基于待处理资源交换集合生成目标资源交换区块。值得注意的是，待处理资源交换集合中的每笔资源交换都包含资源交换标识，且属于同一对象的各笔资源交换的资源交换标识不相同。接着，子链节点1051向验证节点发送包含目标资源交换区块的验证指示信息，指示验证节点对该目标资源交换区块中的资源交换进行正确性验证。这里，验证节点可以是区块链网络103中的节点，也可以是区块链网络103之外的节点，本申请实施例对此不做限制。验证节点对目标资源交换区块进行正确性验证后，生成针对该目标资源交换区块的验证数据，并将该验证数据发送至业务主链104中的主链节点1041。主链节点1041对验证数据进行有效性校验，得到该验证数据的校验结果，再将该校验结果返回子链节点1051，子链节点1051便可以根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。通过这种方式，可以将业务主链上的资源交换转移到业务子链上，缓解业务主链的存储压力，解决业务主链TPS(Transaction processing systems，每秒事务处 理量，是一种表达系统处理能力的性能指标)不足的问题；同时，由于每笔资源交换都包含有资源交换标识，且属于同一对象的各笔资源交换的用不同资源交换标识来区分，如此保证了业务子链上的资源交换不会被重复处理，避免出现资源交换双花，有利于增加系统的安全性。
需要说明的是，本申请实施例中所涉及业务主链的主链节点和业务子链的子链节点可以是接入区块链网络中的服务器或者终端。其中，服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、CDN、以及大数据等基于云计算服务的云服务器。终端可以是智能手机(如Android手机、iOS手机等)、平板电脑、笔记本电脑、台式计算机、智能音箱、智能手表等，但并不局限于此。各个节点之间可以通过有线或无线通信方式进行直接或间接地连接，本申请在此不做限制。
下面结合附图对本申请实施例提供的基于区块链的数据处理方法进行详细说明。
请参见图4，是本申请实施例提供的一种基于区块链的数据处理方法的流程示意图，该区块链网络可以包括业务主链和业务子链，该方法可以由业务子链对应的子链节点执行，包括但不限于以下步骤：
S401、从业务子链对应的资源交换池中获取待处理资源交换集合。
在本申请实施例中，业务子链中的子链节点可以从业务子链对应的资源交换池中获取待处理资源交换集合，待处理资源交换集合中包括多个不同对象的多笔待处理资源交换，其中，每笔资源交换都包含资源交换标识，且属于同一对象的各笔资源交换的资源交换标识不同。这里的资源交换标识是指用以表示属于同一对象的各笔资源交换的生成顺序的一种标识，例如可以是一个具体的数值。举例来说，假设从业务子链对应的资源交换池中获取到的待处理资源交换集合中，属于对象A的资源交换有资源交换a、资源交换b以及资源交换c，若三笔资源交换的资源交换顺序为资源交换b先于资源交换a，资源交换a先于资源交换c，则资源交换b对应的资源交换标识可以为数值1，资源交换a对应的资源交换标识可以为数值2，资源交换c对应的资源交换标识可以为数值3。在一种实现方式中，属于同一对象的各笔资源交换的资源交换标识可以是基于各笔资源交换的生成顺序线性增长的数值，也可以是基于各笔资源交换的生成顺序指数增长的数值，还可以为是基于各笔资源交换的生成顺序对数增长的数值，本申请对此不做限制。
在一个实施例中，子链节点从业务子链对应的资源交换池中获取待处理资源交换集合的方式具体可以是，先从业务子链对应的资源交换池中获取待处理资源交换，这里资源交换池中的每笔资源交换也是包含上述资源交换标识的资源交换，由于该资源交换标识可以表示属于同一对象的各笔资源交换的生成顺序，基于待处理资源交换的资源交换标识，则可以检测已经获取到的资源交换所构成的待处理资源交换集合中是否包含该待处理资源交换；若已经获取到的资源交换所构成的待处理资源交换集合中未包含该待处理资源交换，即表明已经获取到的资源交换所构成的待处理资源交换集合中的资源交换包含的资源交换标识，与待处理资源交换的资源交换标识不相同，则可以将待处理资源交换加入待处理资源交换集合中；若已经获取到的资源交换所构成的待处理资源交换集合中包含该待处理资源交换，即表明已经获取到的资源交换所构成的待处理资源交换集合中的资源交换包含的资源交换标识，存在与待处理资源交换的资源交换标识相同的，则将该待处理资源交换舍弃，或者，将该待处理资源交换从资源交换池中删除。通过这种方式，可以避免待处理资源交换集合中存在资源交换标识相同的资源交换，导致相同的资源交换被重复执行。
在一种可能实现的方式中，子链节点获取到待处理资源交换集合后，可以通过树形数据结构来保存属于各个对象的资源交换，保存有各个对象的资源交换的树可以称之为状态树。其中，状态树包括叶子节点和根，叶子节点可以存储属于各个对象的资源交换，根可以存储各个对象对应的资源交换状态数据，当子链执行各笔资源交换时，则对应修改状态树中的叶子节点，各个对象对应的各笔资源交换执行完成后则更新状态树中的根存储的各个对象对应的资源交换状态数据。需要说明的是，在对各个对象对应的资源交换状态数据进行更新之前，还需要分别执行步骤S402和步骤S404描述的两方面的验证，以此确保数据真实性，增强系统的安全性。下面对子链节点获取到待处理资源交换集合之后如何进行验证的过程加以说明。
S402、基于待处理资源交换集合生成目标资源交换区块，并向验证节点发送包含目标资源交换区块的验证指示信息。
在本申请实施例中，子链节点可以将待处理资源交换集合中各待处理资源交换对应的区块打包处理为目标资源交换区块，然后再向验证节点发送包含该目标资源交换区块的验证指示信息，以指示验证节点对目标资源交换区块中的资源交换进行正确性验证。其中，验证节点是指验证获取到的 资源交换是否正确的节点，目的是保证资源交换的完备性和正确性，该验证节点可以是区块链网络中的节点，也可以是区块链网络之外的节点，其中，在生成目标资源交换区块时，子链节点收集包含各笔待处理交易资源交换的区块，并将根据收集的待处理交易资源交换的区块进行打包处理，生成上述目标资源交换区块。
在一个实施例中，子链节点向验证节点发送包含目标资源交换区块的验证指示信息之后，验证节点可以对目标资源交换区块中的资源交换进行正确性验证。当验证节点对目标资源交换区块中的资源交换进行验证时，为了确保资源交换的私密性，本申请实施例中，在验证节点不知道资源交换的具体内容的情况下，完成对目标资源交换区块中的资源交换的正确性验证。为了实现上述目的，验证节点可以采用零知识证明算法对目标资源交换区块中的资源交换进行验证，零知识证明算法的特点是一方通过零知识证明向另一方证明某个论断，同时不泄露该论断包含的保密信息，另一方可以通过验证零知识证明相信论断的正确性，同时也无法获取任何保密信息。因此，验证节点可以基于零知识证明算法对目标资源交换区块中的资源交换进行验证，并生成该目标资源交换区块的验证数据，该零知识证明算法例如可以是零知识简洁非交互式知识论证(zero-knowledge succinct non-interactive argument of knowledge，zkSNARK)，椭圆曲线加密算法，RSA(以Rivest、Shamir、Adleman三位数学家的名字命名)算法等等。通过验证节点对目标资源交换区块中的资源交换进行正确性验证，可以确保每笔资源交换的资源交换逻辑正确，增强系统的稳定性。
具体的，若目标资源交换区块中的资源交换通过验证节点基于零知识证明算法的验证，即表明目标资源交换区块中的资源交换正确，则生成的验证数据可以是基于零知识证明算法得到的一个证明(proof)；若目标资源交换区块中的资源交换未通过验证节点基于零知识证明算法的验证，即表明目标资源交换区块中的资源交换存在错误，则生成的验证数据可以是用于指示资源交换错误的字符或者是数值。其中，目标资源交换区块中的资源交换存在错误的情况可以是以下几种：①目标资源交换对象的账户中没有足够的余额支付待处理资源交换中的转账金额，或者是手续费；②目标资源交换对象对应的资源交换中包含的资源交换标识不正确；③目标资源交换对象对应的资源交换签名不正确。这里，目标资源交换对象可以是存在资源交换错误的任意一个对象。
S403、接收验证节点返回的针对目标资源交换区块的验证数据。
在本申请实施例中，验证节点完成对目标资源交换区块中的资源交换的正确性验证之后，子链节点可以接收验证节点返回的针对目标资源交换区块的验证数据。若子链节点接收到的验证数据指示目标资源交换区块正确性验证通过，即表明目标资源交换区块中的资源交换逻辑正确，需要进一步由业务主链的主链节点进行有效性校验，此时执行步骤S404；若子链节点接收到的验证数据指示目标资源交换区块正确性验证未通过，即表明目标资源交换区块中的资源交换存在错误，此时可以将目标资源交换区块中的资源交换确定为无效资源交换，放弃执行该目标资源交换区块中的资源交换。
S404、当验证数据指示目标资源交换区块正确性验证通过时，将验证数据发送至业务主链对应的主链节点，以使主链节点对验证数据进行有效性校验。
在本申请实施例中，当验证数据指示目标资源交换区块正确性验证通过时，子链节点可以将验证数据发送至业务主链对应的主链节点，以使主链节点进一步对验证数据进行有效性校验。主链节点对验证数据的有效性校验，目的是防止子链节点作恶，例如恶意修改某个对象的资源交换，或者是恶意不搜集某个对象的资源交换等等，如果子链节点有任何作恶操作，上述验证数据将无法通过主链节点的有效性校验。主链节点对验证数据进行有效性校验的过程可见图6所示实施例中的步骤S602，在此先不做赘述。
在一个实施例中，子链节点在发送验证数据至主链节点时，还可以基于关键资源交换信息生成关键资源交换信息集合，并将该关键资源交换信息集合也发送至主链节点。关键资源交换信息是指用于描述待处理资源交换集合中的每笔资源交换的精简信息，相较于每笔资源交换对应的完整资源交换信息，省去了一些非必要的数据，以达到节省存储空间的目的，这是因为在相同存储容量的前提下，每笔资源交换所占存储空间越小，能容纳的资源交换数量也就越多。在一些实施例中，每笔资源交换所包含的完整资源交换信息例如可以有资源交换转账方(from)，资源交换接收方(to)，资源交换量(amount)，手续费(fee)，资源交换标识(nonce)，资源交换签名(signature)，完整资源交换信息对应的格式可以是(from，to，amount，fee，nonce，signature)；相应地，每笔资源交换所包含关键资源交换信息则可以只有资源交换转账方，资源交换接收方，资源交换量，资源交换标识，关键资源交换信息对应的格式可以是(from，to，amount，nonce)，由此可见关键资源交换信息相较于完整资源交换信息更加精简，有利于节省存储空间。
进一步的，关键资源交换信息集合可以是将各个关键资源交换信息按照资源交换顺序进行排序后得到的，主链节点根据关键资源交换信息集合中的关键资源交换信息，可以确定第二对象的资源交换状态数据，该第二对象可以是待处理资源交换集合中的资源交换所关联的任意一个对象。其中，资源交换关联的对象可以是该笔资源交换对应的资源交换转账方，也可以是资源交换接收方。在一种可能的实现方式中，当子链节点发送至主链节点的验证数据未通过有效性校验时，主链节点可以判断子链节点有作恶嫌疑，此时主链节点可以选择不信任此子链节点，主链节点基于关键资源交换信息集合可以自行执行各笔资源交换，以确定各个对象的资源交换状态数据。同时，由于关键资源交换信息集合是关键资源交换信息按照资源交换顺序排序后得到的，主链节点在基于关键资源交换信息集合执行各笔资源交换时也会更加便捷，以此减少主链节点的处理压力。
S405、接收主链节点返回的验证数据的校验结果，并根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。
在本申请实施例中，主链节点对验证数据进行有效性校验之后，子链节点可以接收主链节点返回的校验结果，并根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。
在一个实施例中，当子链节点接收到的校验结果指示验证数据通过有效性校验时，可以执行待处理资源交换集合中的每笔资源交换，得到每笔资源交换的资源交换执行结果，然后再根据每笔资源交换的资源交换数据和资源交换执行结果，对资源交换所属的各个对象的资源交换状态数据进行更新。其中，资源交换执行结果用于指示当前资源交换是否执行成功，因为实际应用中，可能会存在资源交换执行失败的问题，例如网络不稳定导致资源交换执行失败，所以只有在资源交换执行结果指示当前资源交换执行成功的情况下，子链节点才会根据每笔资源交换的资源交换数据更新资源交换所属对象的资源交换状态数据。
在一个实施例中，子链节点更新各笔资源交换所属对象的资源交换状态数据之后，在满足状态数据上报条件时，可以将记录的各个对象的资源交换状态数据发送至主链节点，以使主链节点基于接收到的资源交换状态数据对其记录的各个对象的资源交换状态数据进行更新。其中，满足状态数据上报条件可以包括以下任意一项或多项：①当前阶段已执行资源交换的数量达到预设数量；例如预设数量为100笔，则已执行资源交换的数量达到100笔时，子链节点便可以将各个对象的资源交换状态数据发送至主链节点。②资源交换池中的资源交换已全部执行；若资源交换池中的资源交换都已执行，当前已无待处理资源交换，此时子链节点也可以将各个对象的资源交换状态数据发送至主链节点。③当前时间间隔达到预设时间间隔；例如预设时间间隔为10分钟，则子链节点可以每间隔10分钟向主链节点发送一次各个对象的资源交换状态数据，以便于主链节点可以及时对其记录的各个对象的资源交换状态数据进行更新。
在另一个实施例中，当子链节点接收到的校验结果指示验证数据未通过有效性校验时，则可以终止待处理资源交换集合中的资源交换，也即放弃执行处理资源交换集合中的资源交换，避免出现资源交换问题，影响系统的安全性。
为了便于理解，请参见图5，图5是本申请实施例提供的一种基于区块链的数据处理的场景示意图。如图5所示，整个数据处理过程可以概括为三个部分：(1)子链节点501从业务子链对应的资源交换池50中获取待处理资源交换集合，这里，待处理资源交换集合中的每笔资源交换都包含资源交换标识，且属于同一对象的各笔资源交换的资源交换标识不相同，然后子链节点501将待处理资源交换集合打包处理为目标资源交换区块，再向验证节点502发送包含该目标资源交换区块的验证指示信息；(2)验证节点502接收到的目标资源交换区块后，对目标资源交换区块中的资源交换进行正确性验证，并向子链节点501返回生成验证数据，验证节点502可以是基于零知识证明算法对目标资源交换区块中的资源交换进行验证，如此有利于保障数据的私密性，若目标资源交换区块中的资源交换通过验证节点的正确性验证，则子链节点501可以将验证数据发送至主链节点503进一步进行有效性校验；(3)主链节点503对验证数据进行有效性校验后，生成针对验证数据的校验结果，并向子链节点501返回校验结果，子链节点501根据校验结果可以对待处理集合中的每笔资源交换进行相应处理，若校验结果指示验证数据通过有效性校验时，子链节点501便可以执行待处理资源交换集中的每笔资源交换，到每笔资源交换的资源交换执行结果，然后再根据每笔资源交换的资源交换数据和资源交换执行结果，对资源交换所属的各个对象的资源交换状态数据进行更新。
本申请实施例通过子链节点从业务子链对应的资源交换池中获取待处理资源交换集合，然后基于待处理资源交换集合生成目标资源交换区块，再将该目标资源交换区块发送至验证节点进行正确性验证，并接收验证节点的验证数据，当验证数据指示目标资源交换区块通过正确性验证时，将该验证数据发送至主链节点进行有效性校验，并接收主链节点的校验结果，最后根据校验结果对待处 理资源交换集合中的每笔资源交换进行相应处理。通过这种方式，一方面，由于待处理资源交换集合中的每笔资源交换都包含资源交换标识，子链节点可以根据资源交换标识保证待处理资源交换集合中不存在重复资源交换，确保了相同的资源交换不会被重复执行，避免了资源交换双花问题，增加了系统的安全性。另一方面，主链节点不需要执行每笔资源交换，只需要对验证数据进行校验，在校验通过时，可以由子链节点执行待处理资源交换集合中的每笔资源交换，如此提升了主链节点资源交换的TPS和处理性能，也缓解了主链节点的存储压力。总而言之，通过实施本申请实施例，可以在实现对主链节点进行扩容的同时保证系统安全性。
进一步的，请参见图6，是本申请实施例提供的另一种基于区块链的数据处理方法的流程示意图，该区块链网络可以包括业务主链和业务子链，该方法可以由业务主链对应的主链节点执行，包括但不限于以下步骤：
S601、接收业务子链对应的子链节点发送的验证数据。
在本申请实施例中，主链节点可以接收业务子链对应的子链节点发送的验证数据。其中，验证数据是验证节点对目标资源交换区块中的资源交换进行正确性验证后生成的，目标资源交换区块是子链节点基于待处理资源交换集合生成的，待处理资源交换集合中的每笔资源交换是从业务子链对应的资源交换池中获取的，每笔资源交换都包含资源交换标识，且属于同一对象的各笔资源交换的资源交换标识不相同。值得注意的是，只有当验证数据指示目标资源交换区块通过正确性验证时，子链节点才会向主链节点发送该验证数据，反之，则不发送。
S602、对验证数据进行有效性校验，得到验证数据的校验结果。
在本申请实施例中，主链节点可以对接收到的验证数据进行有效性校验，得到验证数据的校验结果。其中，验证数据可以包括目标资源交换区块对应的校验数据，以及利用验证节点对应的加密密钥对校验数据进行加密处理得到的加密数据。这里，校验数据是用于指示目标资源交换区块通过正确性验证的数据，可以是一个数值，举例来说，当验证节点基于零知识证明算法对目标资源交换区块进行验证时，该校验数据便可以是验证节点基于零知识证明算法生成的proof的值。此外，对校验数据进行加密处理的加密密钥可以是对称密钥，也可以是非对称密钥，对称密钥即用于加密的加密密钥和用于解密的解密密钥是一致的，非对称密钥即用于加密的加密密钥和用于解密的解密密钥是存在区别的。相应地，获取加密密钥的加密算法可以是对称加密算法，例如，DES算法(Data Encryption Standard，数据加密标准)，3DES算法，Blowfish算法(由布鲁斯·施奈尔开发的区块加密算法)等等，还可以是非对称加密算法，例如，背包算法、RSA算法、ECC(椭圆曲线加密)算法等等。
在一个实施例中，主链节点对验证数据进行有效性校验的方式可以是，获取与加密密钥相匹配的解密密钥，利用解密密钥对验证数据包括的加密数据进行解密，得到解密数据，然后再基于验证数据包括的校验数据和解密数据的比较结果，确定验证数据的校验结果。具体的，解密密钥可以存储在主链节点智能合约中，若主链节点利用解密密钥对验证数据包括的加密数据进行解密得到的解密数据，与验证数据包括的校验数据相同，则表明验证数据通过了主链节点的有效性校验；反之，若主链节点利用解密密钥对验证数据包括的加密数据进行解密得到的解密数据，与验证数据包括的校验数据不相同，则表明验证数据未通过主链节点的有效性校验。
在一个实施例中，主链节点可以接收子链节点发送的各个对象的资源交换状态数据，当上述验证数据通过有效性校验时，主链节点可以基于接收到的资源交换状态数据对记录的各个对象的资源交换状态数据进行更新。需要说明的是，子链节点向主链节点发送各个对象的资源交换状态数据的触发时机可以是在子链节点满足一定上报条件时，这里的上报条件例如可以是当前阶段子链节点已执行资源交换的数量达到预设数量，或者是资源交换池中的资源交换已经全部执行，又或者是达到预设时间间隔等等。
在一个实施例中，主链节点还可以接收子链节点发送的关键资源交换信息集合，并存储该关键资源交换信息集合，当上述验证数据未通过有效性校验时，主链节点可以基于关键资源交换信息集合中的每笔资源交换的关键资源交换信息来确定目标对象的资源交换状态数据，目标对象可以是待处理资源交换集合中的资源交换所关联的任一对象。
在一种可能的实现方式中，主链节点也可以通过树形数据结构来保存各个对象的资源交换，各个对象对应的关键资源交换信息可以保存在树的叶子节点中，各个对象对应的资源交换状态数据则保存在树的根中，这个根可以代表当前系统中所有对象的资源交换状态。相应地，当上述验证数据通过主链节点的有效性校验时，主链节点可以根据接收到的各个对象的资源交换状态数据直接更新树中的根，如此，子链节点执行一批资源交换，对应主链节点可以只需更新根存储的资源交换状态 数据，从而提高主链节点的运行效率；当上述验证数据未通过主链节点的有效性校验时，则需要主链节点根据叶子节点中存储的关键资源交换信息更新整个树，以确保各个对象的资源交换状态数据可以被正确更新，增强系统稳定性。
S603、将校验结果发送至子链节点，以使子链节点根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。
在本申请实施例中，主链节点可以将校验结果发送至子链节点，以使子链节点根据该校验结果对待处理集合中的每笔资源交换进行相应处理。子链节点根据校验结果对待处理集合中的每笔资源交换进行相应处理的过程，可见图4所示实施例中步骤S405的详细描述，在此不再赘述。
本申请实施例中主链节点通过对接收到的子链节点发送的验证数据进行有效性验证，得到验证数据的校验结果，再将校验结果返回至子链节点，使子链节点可以根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。通过这种方式，主链节点只需确认子链节点发送的验证数据通过校验，即可直接更新各个对象的资源交换状态数据，提升了主链节点的TPS，同时也缓解了主链节点的存储压力。
前文详细描述了本申请实施例提出的基于区块链的数据处理方法，为了便于理解本方案，下文将从具体应用场景的角度对本申请进一步阐述。
本申请实施例提出的基于区块链的数据处理方法可以应用于数字商品资源交换的业务场景中，可以解决非同质化权益证明凭证在区块链网络中资源交换速度慢，资源交换被重复打包的问题。具体的，本申请实施例的应用场景可以包括但不限于数字商品从主链节点到子链节点的存款，子链节点的数字商品退款到主链节点(withdraw)，更新对象信息(updataAccount)，数字商品资源交换(transfer)。下面以数字商品从主链节点到子链节点的存款为例进行说明。
请参见图7，是本申请实施例提供的一种基于区块链的数据处理的应用场景示意图。如图7所示，①对象A向主链节点提交了一项存款资源交换，存款权益证明凭证(Token)A，数量10。其中，Token可以理解为区块链中可流通的权益证明凭证，可作为资源交换的基本单位。②主链节点可以向子链节点发送对象A的存款资源交换请求，子链节点接收资源交换请求后可以获取待处理资源交换集合，该待处理资源交换集合中包括对象A对应的待处理资源交换(对象A存款Token A，数量10)，并记录对象A对应的该笔待处理资源交换的资源交换标识，例如资源交换标识可以为1，相应地，当对象A再次发送下一笔待处理资源交换时，则资源交换标识将为2，如此可以防止资源交换被重复执行。③子链节点将待处理资源交换集合打包处理为目标资源交换区块，并将包含目标资源交换区块的验证指示信息发送至验证节点，验证节点可以基于零知识证明算法对目标资源交换区块进行验证，生成验证数据。④当验证数据指示目标资源交换区块正确性验证通过时，子链节点可以将验证数据发送至主链节点，使主链节点对验证数据进行有效性校验，此外，子链节点还可以将关键资源交换信息集合也发送至主链节点，使主链节点可以根据关键资源交换信息集合确定各个对象的资源交换状态数据。⑤主链节点对验证数据进行有效性验证之后，可以生成验证数据的校验结果，若校验结果指示验证数据通过有效性校验，则子链节点可以执行待处理资源交换集合中的资源交换。子链节点执行待处理资源交换(对象A存款TokenA，数量10)的过程可见图8，如图8所示，子链节点可以通过树形数据结构管理属于各个对象的资源交换，针对对象A，状态更新之前叶子节点中已存储数量10的TokenA，执行待处理资源交换(对象A存款TokenA，数量10)后，对象A对应的叶子节点中将存储数量20的TokenA，同时，树形数据结构中的根也会随之更新，可以理解的是，根存储的是各个对象的资源交换状态数据的哈希值。⑥主链节点可以接收子链节点发送的各个对象的资源交换状态数据，并根据接收到的各个对象的资源交换状态数据对智能合约中记录的资源交换状态数据进行更新，如资源交换对象A存款数量10的TokenA后，得到数量20的TokenA，则对应将智能合约中对象A的状态变更为对象A，TokenA的数量20。通过这种方式，可以提升非同质化权益证明凭证在主链节点上的流通速度，同时保证子链节点的资源交换不会被重复打包，增强系统的安全性。
另外，需要说明的是，用于执行上述方法实施例中各步骤的执行载体可以是由硬件构成，也可以是由软件构成，还可以是由软硬件结合构成。在本申请的具体实施方式中，涉及到待处理资源交换、资源交换数据、目标资源交换对象、资源交换状态数据、账户等相关的数据，所涉及使用到的数据均是经过对象授权的。当本申请以上实施例运用到具体产品或技术中时，所涉及使用到的数据需要获得对象许可或者同意，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法规和标准。

在一个实施例中，处理器1003还用于：通过通信接口1001在满足状态数据上报条件时，将记录的各个对象的资源交换状态数据发送至主链节点，以使主链节点基于接收到的资源交换状态数据对其记录的各个对象的资源交换状态数据进行更新。
在一个实施例中，满足状态数据上报条件包括：当前阶段已执行资源交换的数量达到预设数量，或者资源交换池中的资源交换已全部执行。
在其他可行的实施例中，该计算机设备可以对应于前文所述的业务主链的主链节点，此时，处理器1003通过运存储器 1002中的可执行程序代码，执行如下操作：通过通信接口1001接收业务子链对应的子链节点发送的验证数据，其中，验证数据为验证节点对目标资源交换区块中的资源交换进行正确性验证后生成的，目标资源交换区块为子链节点基于待处理资源交换集合生成的，待处理资源交换集合中的每笔资源交换是从业务子链对应的资源交换池中获取的，每笔资源交换包含资源交换标识，且属于同一对象的各笔资源交换的资源交换标识不同；验证数据是子链节点在验证数据指示目标资源交换区块正确性验证通过时发送的；对验证数据进行有效性校验，得到验证数据的校验结果；将校验结果发送至子链节点，以使子链节点根据校验结果对待处理资源交换集合中的每 笔资源交换进行相应处理。
在一个实施例中，验证数据包括目标资源交换区块对应的校验数据、利用验证节点对应的加密密钥对校验数据进行加密处理得到的加密数据；处理器1003对验证数据进行有效性校验，得到验证数据的校验结果时，具体用于：获取与加密密钥相匹配的解密密钥，利用解密密钥对验证数据包括的加密数据进行解密，得到解密数据；基于验证数据包括的校验数据和解密数据的比较结果，确定验证数据的校验结果。

具体实现中，本申请实施例中所描述的通信接口1001、存储器1002和处理器1003可执行本申请实施例提供的基于区块链的数据处理方法中所描述的业务子链的子链节点和业务主链的主链节点的实现方式，也可执行本申请实施例提供的基于区块链的数据处理装置中所描述的实现方式，在此不再赘述。
本申请实施例通过子链节点从业务子链对应的资源交换池中获取待处理资源交换集合，然后基于待处理资源交换集合生成目标资源交换区块，再将该目标资源交换区块发送至验证节点进行正确性验证，并接收验证节点的验证数据，当验证数据指示目标资源交换区块通过正确性验证时，将该验证数据发送至主链节点进行有效性校验，并接收主链节点的校验结果，最后根据校验结果对待处理资源交换集合中的每笔资源交换进行相应处理。通过这种方式，一方面，由于待处理资源交换集合中的每笔资源交换都包含资源交换标识，子链节点可以根据资源交换标识保证待处理资源交换集合中不存在重复资源交换，确保了相同的资源交换不会被重复执行，避免了资源交换双花问题，增加了系统的安全性。另一方面，主链节点不需要执行每笔资源交换，只需要对验证数据进行校验，在校验通过时，可以由子链节点执行待处理资源交换集合中的每笔资源交换，如此提升了主链节点的处理性能，也缓解了主链节点的存储压力。总而言之，通过实施本申请实施例，可以在实现对主链节点进行扩容的同时保证系统安全性。
本申请实施例还提供了一种计算机可读存储介质，所述计算机可读存储介质中存储有计算机程序，当其在计算机上运行时，使得计算机实现如本申请实施例所述的基于区块链的数据处理方法。其具体实现方式可参考前文描述，此处不再赘述。

需要说明的是，对于前述的各个方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术对象应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某一些步骤可以采用其他顺序或者同时进行。其次，本领域技术对象也应该知悉，说明书中所描述的实施例所涉及的动作和模块并不一定是本申请所必须的。
本领域普通技术对象可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属本申请所涵盖的范围。
