Description

平行链共识方法、设备及存储介质 技术领域
本申请涉及区块链技术领域，具体涉及一种平行链共识方法、设备及存储介质。
背景技术
在申请人所提出的平行链共识机制中，平行链节点从主链同步平行链交易以生成平行链区块，平行链的各授权节点分别根据当前节点的平行链区块执行结果打包(分别在主链和平行链执行的)共识交易并发送至主链节点；
主链节点将各共识交易记录到主链上以进行投票，符合预配置条件(例如，超过2/3的投票一致，等等)则该平行链区块共识成功，从而借助主链共识完成平行链共识；
平行链节点从主链同步到上述各共识交易并打包执行后，在本地进行投票以完成平行链自共识。
在上述平行链共识机制中，当平行链的部分授权节点未正常进行平行链共识，导致平行链共识无法正常完成时，需要重新配置平行链的授权账户组，此时存在平行链授权账户组重新配置后，无法触发对之前共识失败的平行链区块重新进行平行链共识的问题。
发明内容
鉴于现有技术中的上述缺陷或不足，期望提供一种重新配置平行链授权账户组后灵活触发平行链共识的平行链共识方法、设备及存储介质。
第一方面，本发明提供一种适用于主链节点的平行链共识方法，主链上所配置的用于进行平行链共识的合约和用于更新平行链账户组的合约为同一合约，该方法包括：
通过上述合约执行若干笔平行链账户组更新交易以更新第一平行链的平行链授权账户组：
更新成功，则根据更新后的平行链授权账户组进行第一平行链的平行链共识。
第二方面，本发明还提供一种适用于平行链节点的平行链共识方法，平行链上所配置的用于进行平行链自共识的合约和用于更新平行链账户组的合约为同一合约，该方法包括：
通过该合约执行若干笔平行链账户组更新交易以更新当前平行链的平行链授权账户组：
更新成功，则根据更新后的平行链授权账户组进行当前平行链的平行链自共识。
第三方面，本发明还提供一种设备，包括一个或多个处理器和存储器，其中存储器包含可由该一个或多个处理器执行的指令以使得该一个或多个处理器执行根据本发明各实施例提供的平行链共识方法。
第四方面，本发明还提供一种存储有计算机程序的存储介质，该计算机程序使计算机执行根据本发明各实施例提供的平行链共识方法。
本发明诸多实施例提供的平行链共识方法、设备及存储介质通过将主链上的平行链共识和平行链账户组更新配置在同一合约中，从而可以通过该合约在主链上更新平行链授权账户组后直接触发平行链共识，实现了在重新配置平行链授权账户组后直接在主链触发平行链共识，而无需由平行链重新触发；
本发明一些实施例提供的平行链共识方法、设备及存储介质进一步通过将触发机制配置为仅在授权账户数量未增多时触发平行链共识，避免在暂时无法共识成功时触发共识，优化了共识机制。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1为本发明一实施例提供的一种平行链共识方法的流程图。
如图1所示，在本实施例中，本发明提供一种适用于主链节点的平行链共识方法，主链上所配置的用于进行平行链共识的合约和用于更新平行链账户组的合约为同一合约，该方法包括：
S12：通过上述合约执行若干笔平行链账户组更新交易以更新第一平行链的平行链授权账户组：
更新成功，则执行步骤S14：根据更新后的平行链授权账户组进行第一平行链的平行链共识。
以平行链共识成功的条件配置为超过2/3的投票一致，第一平行链Pa的平行链授权账户组配置有6个授权节点a-f，其中授权节点a-d正常运行，在平行链高度h＝h 1的平行链区块共识成功后分别向主链发送h＝h 1+1的共识交易tx a-(h1+1)-tx d-(h1+1)，而授权节点e和f自平行链高度h＝h 1起出现异常，导致h＝h 1+1的平行链区块无法完成平行链共识为例：
在当前的平行链共识方案中，通过授权账户投票等任一方法使授权节点e和f退出Pa链的授权节点账户组后，授权节点a-d的平行链共识模块无法感知到Pa链的授权节点账户组的变动，与此同时，当主 链上所配置的用于进行平行链共识的合约和用于更新平行链账户组的合约为不同合约时，主链上用于进行平行链共识的合约同样无法感知到Pa链的授权节点账户组的变动，导致无法触发h＝h 1+1的平行链区块的平行链共识。
在申请人同期提交的另一件专利申请中，申请人提出了由平行链授权节点通过监测平行链区块共识超时来触发重发共识交易的平行链共识触发方案，此处不具体展开；在本申请中，通过将主链上所配置的用于进行平行链共识的合约和用于更新平行链账户组的合约配置为同一合约，使得该合约可以在感知到平行链的授权节点账户组的变动时触发平行链共识。
在上述示例中，当授权节点a-d分别向主链节点发送授权节点账户组更新交易tx a-tx d，在步骤S12中，主链节点分别广播tx a-tx d、将tx a-tx d打包到若干个主链区块中，并通过上述合约分别执行tx a-tx d，并在执行其中的最后一笔授权节点账户组更新交易(例如tx d)时判断第一平行链Pa的平行链授权账户组是否更新成功：
否，则不触发平行链共识；
是，则执行步骤S14：根据更新后的Pa链的授权节点账户组(例如a-d)进行第一平行链的平行链共识：通过上述合约根据更新后的Pa链的授权节点账户组中的各授权节点a-d此前分别发送至主链的h＝h 1+1的各笔共识交易tx a-(h1+1)-tx d-(h1+1)进行平行链共识。
上述实施例通过将主链上的平行链共识和平行链账户组更新配置在同一合约中，从而可以通过该合约在主链上更新平行链授权账户组后直接触发平行链共识，实现了在重新配置平行链授权账户组后直接在主链触发平行链共识，而无需由平行链重新触发。
图2为图1所示方法的一种优选实施方式的流程图。如图2所示，在一优选实施例中，步骤S14包括：
S141：判断更新后的平行链授权账户组中的授权账户数量相较于更新前是否增多：
否，则执行步骤S143：根据更新后的平行链授权账户组中各授权账户分别生成、由上述合约执行成功并记录在主链上的第一平行链区 块的各第一共识交易对第一平行链区块进行平行链共识。
具体地，以步骤S12中Pa链的授权节点账户组由a-f变更为a-g为例，由于此时新的授权节点g尚未向主链节点发送h＝h 1+1的共识交易，导致此时触发平行链共识仍无法令h＝h 1+1的平行链区块共识成功(4/7＜2/3)，而需要等待授权节点g向主链节点发送h＝h 1+1的共识交易tx g-(h1+1)之后，由上述合约执行tx g-(h1+1)并触发h＝h 1+1的平行链区块的平行链共识(5/7＞2/3)。
在步骤S141中，判断更新后的平行链授权账户组中的授权账户数量相较于更新前是否增多：
是，则不触发平行链共识，等待上述合约执行新的授权节点发送的第一平行链区块的共识交易；
否，则执行步骤S143，触发平行链共识。
其中，在步骤S143中，(在授权账户数量减少或不变时)仍有一定概率因为新的授权节点尚未发送第一平行链区块的共识交易，或，原有授权节点异常等原因导致平行链共识失败，此时同样等待上述合约执行新的授权节点发送的第一平行链区块的共识交易，或，等待再次更新平行链授权账户组以再次触发平行链共识。
上述实施例进一步通过将触发机制配置为仅在授权账户数量未增多时触发平行链共识，避免在暂时无法共识成功时触发共识，优化了共识机制。
图3为图1所示方法的一种优选实施方式的流程图。如图3所示，在另一优选实施例中，步骤S14包括：
S142：根据更新后的平行链授权账户组中各授权账户分别生成、由上述合约执行成功并记录在主链上的第一平行链区块的各第一共识交易判断，第一平行链区块是否满足平行链共识成功的条件：
是，则执行步骤S143：根据各第一共识交易对第一平行链区块进行平行链共识。
具体地，在触发平行链共识之前，可以先根据更新后的平行链授权账户组进行判断，主链上当前记录的各笔第一共识交易是否满足平行链共识成功的条件，若不满足则不触发平行链共识。
图4为图1所示方法的一种优选实施方式的流程图。如图4所示，在又一优选实施例中，步骤S14包括：
S141：判断更新后的平行链授权账户组中的授权账户数量相较于更新前是否增多：
否，则执行步骤S142：根据更新后的平行链授权账户组中各授权账户分别生成、由上述合约执行成功并记录在主链上的第一平行链区块的各第一共识交易判断，第一平行链区块是否满足平行链共识成功的条件：
是，则执行步骤S143：根据各第一共识交易对第一平行链区块进行平行链共识。
图4所示方法的触发机制可参照图2和图3所示的方法，此处不再赘述。
与图1-4所示的适用于主链节点的平行链共识方法相似地，本申请还提供一组适用于平行链节点的平行链共识方法，由于平行链进行自共识的原理与主链进行平行链共识的原理相同，因此该组方法与图1-4所示方法的区别仅在于，该组方法由平行链节点执行，具体不再一一赘述。
