Description

非正常挖矿账户的识别方法和惩罚方法、设备和存储介质 技术领域
本申请涉及区块链等技术领域，具体涉及一种非正常挖矿账户的识别方法和惩罚方法、设备和存储介质。
背景技术
现有方案中，是否能挖到矿取决于选票；而不同节点的交易池中的交易不一定完全相同(交易本身可能不同，即使交易相同，存储交易的顺序也不一定相同)。
例如，ticket1被导入到node1、node2、node3进行挖矿，node1、node2、node3交易池中的交易不同；在ticket1挖区块高度为50的矿成功时，node1生成block(50)_1与node2生成block(50)_2与node3生成block(50)_3都彼此不同，产生分叉；由于根据ticket1所生成的区块都是正确的区块，因此可能node4、node1会在block(50)_1后继续挖矿，node5、node2会在block(50)_2后继续挖矿，node6、node3会在block(50)_3后继续挖矿；而最终只有一条链会是主链，假设最终block(50)_1所在的链为主链，则node5、node6在侧链挖矿将损失收益；且上述机制将导致区块链网络产生更多分叉，降低了区块链网络的稳定性。
发明内容
鉴于现有技术中的上述缺陷或不足，期望提供一种保证矿工收益，提高区块链网络稳定性的非正常挖矿账户的识别方法和惩罚方法、设备和存储介质。
第一方面，本发明提供一种适用于区块链节点的非正常挖矿账户的识别方法，选票用于作为挖矿成功时生成区块的挖矿凭证，上述方法包括：
接收第一区块，判断本地是否存有与第一区块的区块高度相同、区块哈希不同的第二区块：
是，则判断用于生成第二区块的第二选票与用于生成第一区块的第一选票是否为相同选票：
是，则将持有第一选票的第一账户标识为非正常挖矿账户。
第二方面，本发明提供一种适用于区块链节点的非正常挖矿账户的惩罚方法，包括：
在广播第三区块前，判断生成第三区块的第三账户是否为如第一方面的非正常挖矿账户的识别方法所标识的非正常挖矿账户：
是，则根据预配置的惩罚规则判断是否惩罚第三账户：
是，则根据预配置的延迟广播规则延迟广播第三区块。
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非正常挖矿账户的识别方法和惩罚方法。
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非正常挖矿账户的识别方法和惩罚方法。
本发明诸多实施例提供的非正常挖矿账户的识别方法和惩罚方法、设备和存储介质通过接收第一区块，判断本地是否存有与第一区块的区块高度相同、区块哈希不同的第二区块：是，则在用于生成第二区块的第二选票与用于生成第一区块的第一选票为相同选票时，将持有第一选票的第一账户标识为非正常挖矿账户的方法识别出非正常挖矿账户，配合相应的惩罚方法对标识为非正常挖矿账户的账户进行惩罚，在保证矿工的挖矿收益同时增强了区块链网络的稳定性。

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非正常挖矿账户的识别方法的流程图。如图1所示，在本实施例中，本发明提供一种适用于区块链节点的非正常挖矿账户的识别方法，选票用于作为挖矿成功时生成区块的挖矿凭证，上述方法包括：
S121：接收第一区块，判断本地是否存有与第一区块的区块高度相同、区块哈希不同的第二区块：
是，则执行步骤S122：判断用于生成第二区块的第二选票与用于生成第一区块的第一选票是否为相同选票：
是，则执行步骤S1221：将持有第一选票的第一账户标识为非正常挖矿账户。
具体地，假设区块链网络中共有7个节点node1～node7；用户A持有ticket1，用户A将ticket1导入node1和node2进行挖矿；在ticket1挖区块高度为50的矿成功时，node1生成block(50)_1，block(50)_1的区块哈希为hash(block(50)_1)，node2生成block(50)_2，block(50)_2的区块哈希为hash(block(50)_2)，；
在第一场景中，node1和node2交易池中的交易不同，node7优先收到block(50)_1，node3～node6优先收到block(50)_2；
由于node1和node2交易池中的交易不同，因此hash(block(50)_1)与hash(block(50)_2)不同，block(50)_1和block(50)_2不同；但由于block(50)_1和block(50)_2都是根据ticket1所生成，因此block(50)_1和block(50)_2都是正确的区块；
在现有技术中，node1与node7在block(50)_1后继续挖矿，而node2～node6在block(50)_2后继续挖矿；而最终只有一条链会是主链，假设最终block(50)_2所在的链为主链，则后续node7在block(50)_1后所生成的块的收益将全部损失；
假设当前区块链节点为node7；
node7执行步骤S121，接收block(50)_2，判断本地是否存有区块高度为50、区块哈希不为hash(block(50)_2)的区块：
由于node7优先收到block(50)_1，node7的本地已存有block(50)_1，hash(block(50)_1)与hash(block(50)_2)不同，则执行步骤S122，判断用于生成block(50)_2的选票与用于生成block(50)_1的选票是否为相同选票：
由于block(50)_2和block(50)_1均由ticket1生成，则执行步骤S1221：将用户A的账户标识为非正常挖矿账户。
若node1和node2交易池中的交易相同，则hash(block(50)_1)与hash(block(50)_2)相同；那么node7接收block(50)_2时，判断本地已有相同的区块(区块高度相同且区块哈希相同)，node7丢弃block(50)_2。
在第二场景中，用户B持有ticket2，用户B将ticket2导入node3进行挖矿；ticket2也成功挖到区块高度为50的块，node3生成block(50)_3；node7优先收到block(50)_1，node4～node6优先收到block(50)_2；
假设当前区块链节点为node7；
node7执行步骤S121，接收block(50)_3，判断本地是否存有区块高度为50的区块：
由于node7优先收到block(50)_1，node7的本地已存有block(50)_1，则执行步骤S122，判断用于生成block(50)_3的选票与用于生成b lock(50)_1的选票是否为相同选票：
由于block(50)_3由ticket2生成，block(50)_1由ticket1生成，则node7丢弃block(50)_3，在block(50)_1后继续挖矿。
若node7所接收的第一区块为block(51)，本地不存在区块高度为51的区块，则以现有技术处理所接收的block(51)(例如在node7本地的最高区块高度为50时，存储block(51)，并在block(51)后继续挖矿)。
在更多实施例中，步骤S121中的区块哈希还可以根据实际需求配置为其它参数，例如配置为状态哈希(步骤S121：接收第一区块，判断本地是否存有与第一区块的区块高度相同、状态哈希不同的第二区块)，可实现相同的技术效果。
上述实施例能识别出非正常挖矿账户，配合相应的惩罚方法对标识为非正常挖矿账户的账户进行惩罚，在保证矿工的挖矿收益同时增强了区块链网络的稳定性。
优选地，选票的选票信息存储于区块的挖矿交易中，图1所示方法中步骤S122包括：
解析第二区块的第二挖矿交易以获取第二选票；
解析第一区块的第一挖矿交易以获取第一选票；
判断第二选票与第一选票是否为相同选票。
在更多实施例中，还可以根据实际需求配置选票的选票信息的获取方式，例如在选票的选票信息存储于区块的区块头中时，图1所示方法中步骤S122包括：
解析第二区块的第二区块头以获取第二选票；
解析第一区块的第一区块头以获取第一选票；
判断第二选票与第一选票是否为相同选票。
优选地，图1所示方法还包括：
在第二选票与第一选票为不同选票时，判断第一区块中的第一交易总数和第二区块中的第二交易总数是否相同：
否，则选取交易总数较大的区块为正确的区块；
是，则解析第一区块的第一区块哈希和第二区块的第二区块哈希，将区块哈希较小的区块确定为正确的区块。
在更多实施例中，在第二选票与第一选票为不同选票时，如何选择到最优的块的方式还可以根据实际需求进行配置，例如配置为：
在第二选票与第一选票为不同选票时，判断第一区块中的第一交易总数和第二区块中的第二交易总数是否相同：
否，则选取交易总数较大的区块为正确的区块；
是，则解析第一区块的第一状态哈希和第二区块的第二状态哈希，将状态哈希较小的区块确定为正确的区块。
上述实施例使得区块链节点在同一高度收到不同选票所挖到的块时，根据最合理的方式纠正到最优的块并基于此块挖矿，及时制止区块链节点在侧链挖矿而造成的资源浪费以及损失。
图2为本发明一实施例提供的一种非正常挖矿账户的惩罚方法的流程图。如图2所示，在本实施例中，本发明提供一种适用于区块链节点的非正常挖矿账户的惩罚方法，上述方法包括：
S221：在广播第三区块前，判断生成第三区块的第三账户是否为如图1所示的非正常挖矿账户的识别方法所标识的非正常挖矿账户：
是，则执行步骤S222：根据预配置的惩罚规则判断是否惩罚第三账户：
是，则执行步骤S2221：根据预配置的延迟广播规则延迟广播第三区块。
具体地，以非正常挖矿账户的标识还包括第一时间周期内的非正常挖矿次数，S222包括根据预配置的第一阈值和第三账户的第三非正常挖矿次数判断是否惩罚第三账户，S2221包括根据第三非正常挖矿次数和预配置的第一数值延迟广播第三区块；预配置的惩罚规则为，将第一阈值配置为5，若账户的非正常挖矿次数到达第一阈值，则惩罚该用户；预配置的延迟广播规则为，若账户的非正常挖矿次数为[0,5)，则在收到该账户所持有的选票所生成的区块时，立即广播该区块，若账户的非正常挖矿次数为[5,10)，则在收到该账户所持有的选票所生成的区块时延迟5s广播该区块，若账户的非正常挖矿次数为[10,+∞)，则在收到该账户所持有的选票所生成的区块时延迟60s广播该区块为例；
假设用户C的账户为非正常挖矿账户，且在第一时间周期内(假设为24h)用户C的账户的非正常挖矿次数为10，用户C所持有的ticket5生成block(100)；
假设当前区块链节点为node7；
node7执行步骤S221，在广播block(100)前，判断生成第三区块的第三账户是否为如图1所示的非正常挖矿账户的识别方法所标识的非正常挖矿账户：
由于用户C的账户为非正常挖矿账户，则执行步骤S222，根据预配置的第一阈值和第三账户的第三非正常挖矿次数判断是否惩罚第三账户：
由于第一阈值为5，用户C的账户的非正常挖矿次数为10，则执行步骤S2221，由于用户C的账户的非正常挖矿次数为10，则延迟60s广播该block(100)。
上述实施例以非正常挖矿账户的标识还包括第一时间周期内的非正常挖矿次数，S222包括根据预配置的第一阈值和第三账户的第三非正常挖矿次数判断是否惩罚第三账户，S2221包括根据第三非正常挖矿次数和预配置的第一数值延迟广播第三区块；预配置的惩罚规则为，将第一阈值配置为5，若账户的非正常挖矿次数到达第一阈值，则惩罚该用户；预配置的延迟广播规则为，若账户的非正常挖矿次数为[0,5)，则在收到该账户所持有的选票所生成的区块时，立即广播该区块，若账户的非正常挖矿次数为[5,10)，则在收到该账户所持有的选票所生成的区块时延迟5s广播该区块，若账户的非正常挖矿次数为[10,+∞)，则在收到该账户所持有的选票所生成的区块时延迟60s广播该区块为例对本实施例的非正常挖矿账户的惩罚原理进行了详细阐述。
在更多实施例中，第一周期时间还可以根据实际需求配置为其它数值，例如48h，可实现相同的技术效果。
在更多实施例中，预配置的惩罚规则还可以根据实际需求进行配置，例如在需要特别严格惩罚非正常挖矿账户的情况下，将惩罚规则中的第一阈值配置为1，可实现相同的技术效果。
在更多实施例中，预配置的延迟广播规则还可以根据实际需求进 行配置，例如配置为若账户的非正常挖矿次数为[0,1)，则在收到该账户所持有的选票所生成的区块时，立即广播该区块，若账户的非正常挖矿次数为[1,10)，则在收到该账户所持有的选票所生成的区块时延迟5s广播该区块，若账户的非正常挖矿次数为[10,+∞)，则在收到该账户所持有的选票所生成的区块时延迟60s广播该区块，可实现相同的技术效果。
在更多实施例中，还可以根据实际需求配置非正常挖矿账户的惩罚方法，只要能够惩罚非正常挖矿账户，从而保证正常挖矿账户的用户的收益，从而提高区块链网络稳定性，可实现相同的技术效果。例如可以配置为，在需要惩罚第三账户的情况下，扣除第三账户所缴纳的保证金。上述扣除保证金的方法也可以与账户的非正常挖矿次数进行关联，例如可以配置为，若账户的非正常挖矿次数为[0,5)，则在收到该账户所持有的选票所生成的区块时，不扣除保证金，若账户的非正常挖矿次数为[5,10)，则在收到该账户所持有的选票所生成的区块时扣除该账户所缴纳的保证金的10％，若账户的非正常挖矿次数为[10,+∞)，则在收到该账户所持有的选票所生成的区块时扣除该账户所缴纳的保证金的50％，可实现相同的技术效果。
优选地，非正常挖矿账户的标识还包括第一时间周期内的非正常挖矿次数，图2所示方法的步骤S222包括：
根据预配置的第一阈值和第三账户的第三非正常挖矿次数判断是否惩罚所述第三账户；
图2所示方法的步骤S2221包括：
根据所述第三非正常挖矿次数和预配置的第一数值延迟广播所述第三区块。
上述实施例的非正常挖矿账户的惩罚原理可参考图2所示的方法，此处不再赘述。
优选地，在图2所示方法的一种优选实施方式中，上述方法还包括：
在第三非正常挖矿次数为零，且第三账户标识为非正常挖矿账户时，将第三账户标识为正常挖矿账户。
优选地，各非正常挖矿账户的信息将被公布于官网。
优选地，在第一账户被标识为非正常挖矿账户时，区块链节点将生成预警信息，并通过预配置的联系方式将该预警信息发送至持有第一账户的用户。
