本发明的数据转发服务器为申请号CN201911073994.9的专利文件中的服务器。
图1为本发明一实施例提供的一种随机数生成方法的流程图。如图1所示，在本实施例中，本发明提供一种适用于用户端的随机数生成方法，上述方法包括：
S12：生成第一随机数，向数据转发服务器发送第一随机数的第一哈希值，以供数据转发服务器将第一哈希值转发给第一通道内的各对手用户端；其中，对手用户端为第一通道内除去当前用户端的其它用户端；
S13：接收数据转发服务器转发的若干第二哈希值；其中，第二哈希值由对手用户端生成第二随机数并对第二随机数进行哈希所生成；
S14：在收到各对手用户端通过数据转发服务器转发的第二哈希值后，向数据转发服务器发送第一随机数，以供数据转发服务器将第一随机数转发给第一通道内的各对手用户端，以供根据预配置的第一排序规则对第一随机数、所持有的第二随机数、数据转发服务器转发的若干第二随机数进行排序以生成第三随机数；
S15：接收数据转发服务器转发的各第二随机数，根据数据转发服务器转发的各第二随机数相应的第二哈希值验证所接收的第二随机数；其中，第二随机数由对手用户端收到当前用户端通过数据转发服务器转发的第一哈希值，以及，第一通道内的其它用户端通过数据转发服务器转发的若干第二哈希值后发送；
S16：根据第一排序规则对第一随机数和数据转发服务器转发的各第二随机数排序以生成第三随机数。
具体地，假设第一通道内的用户为用户a和用户b，a的用户端为A，b的用户端为B，a的随机数为rand(a)，b的随机数为rand(b)，第一排序规则为将哈希值从小到大排序，且hash(rand(a))<hash(rand(b))，以当前用户端为A为例；
在步骤S12中，A生成rand(a)，向数据转发服务器发送hash(rand(a))，数据转发服务器将hash(rand(a))转发给B；(同理，B生成rand(b)，向数据转发服务器发送rand(b)，数据转发服务器将hash(rand(b))转发给A)
在步骤S13中，A接收数据转发服务器转发的hash(rand(b))(同理，B接收数据转发服务器转发的hash(rand(a)))；
在步骤S14中，A在收到B通过数据转发服务器转发的hash(rand(b))后，向数据转发服务器发送rand(a)(同理，B在收到A通过数据转发服务器转发的hash(rand(a))后，向数据转发服务器发送rand(b))；
在步骤S15中，A接收数据转发服务器转发的hash(rand(b))，根据hash(rand(b))验证rand(b)(同理，B接收数据转发服务器转发的hash(rand(a))，根据hash(rand(a))验证rand(a))；
在步骤S16中，若根据hash(rand(b))验证rand(b)成功，由于第一 排序规则为将哈希值从小到大排序，且hash(rand(a))<hash(rand(b))，A根据hash(rand(a))、hash(rand(b))生成第三随机数rand(M)(同理，若根据hash(rand(a))验证rand(a)成功，B根据hash(rand(a))、hash(rand(b))生成第三随机数rand(M))。
上述实施例以假设第一通道内的用户为用户a和用户b，a的用户端为A，b的用户端为B，a的随机数为rand(a)，b的随机数为rand(b)为例进行了详细阐述；
在更多实施例中，还可以根据实际需求将第一通道内的用户数量可根据实际需求配置为大于2的整数个，可实现相同的技术效果(例如，在申请人所提出的申请号为CN201911074050.3的专利申请中，申请人提出了一种适用于多个用户所组成的群组安全高效地进行闪电网络交易的群组交易方法，在上述机制中，第一通道内的用户数量可根据实际需求配置为大于2的整数个)。
在更多实施例中，还可以将第一排序规则配置为从大到小排序，此时第三随机数rand(M)根据hash(rand(b))、hash(rand(a))生成，或配置为其它排序规则，可实现相同的技术效果。
上述实施例在闪电网络中完全随机的生成随机数，保证了用户利益。
优选地，在收到各对手用户端通过数据转发服务器转发的第二哈希值后，向数据转发服务器发送第一随机数包括：
在收到各对手用户端通过数据转发服务器转发的第二哈希值后，验证各收到的第二哈希值是否与第一哈希值不同：
是，则向数据转发服务器发送第一随机数。
具体地，A在收到B通过数据转发服务器转发的hash(rand(b))后，判断hash(rand(b))是否与hash(rand(a))不同：
是，则向数据转发服务器发送rand(a)。
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S16后还包括：
S17：接收包括第三随机数的第一链上交易，将第一链上交易发送至区块链节点，以供区块链节点执行第一链上交易并将第三随机数记 录到区块链上。
第一链上交易可以由第一通道中的任意用户端生成。
图3为本发明一实施例提供的另一种随机数生成方法的流程图。如图3所示，本发明提供一种适用于数据转发服务器的随机数生成方法，上述方法包括：
S22：接收随机数的哈希值，将哈希值转发给第一通道内的其它用户端；其中，随机数由用户端生成；
S24：接收随机数，将随机数转发给第一通道内的其它用户端，以供根据数据转发服务器转发的其它用户端的哈希值验证所接收的随机数，根据预配置的第一排序规则对所持有的随机数、数据转发服务器转发的若干随机数进行排序以生成第一随机数；其中，随机数由用户端在收到各第一通道内的其它用户端通过数据转发服务器转发的哈希值后向数据转发服务器发送。
上述实施例的随机数生成原理可参考图1所示的方法，此处不再赘述。
图4为图3所示方法的一种优选实施方式的流程图。如图4所示，在一优选实施例中，步骤S24后还包括：
S26：接收包括第一随机数的第一链上交易，将第一链上交易发送至区块链节点，以供区块链节点执行第一链上交易并将第一随机数记录到区块链上。
图5为本发明一实施例提供的一种游戏方法的流程图。如图5所示，本发明提供一种适用于用户端的游戏方法，上述方法包括：
S32：向数据转发服务器发送第一游戏信息，以供数据转发服务器将第一游戏信息转发给第一通道内的各对手用户端；
S33：接收数据转发服务器转发的若干第二游戏信息；其中，各第二游戏信息分别由各对手用户端发送至数据转发服务器；
S34：游戏开局后根据图1所示的随机数生成方法生成第三随机数，根据第三随机数生成第一游戏结果；
S35：响应于当前用户结算游戏，根据第一游戏结果生成第一链下结算交易并发送至数据转发服务器，以供数据转发服务器将第一链下 结算交易转发给第一通道内的各对手用户端。
具体地，假设第一通道内的用户为用户a和用户b，a的用户端为A，b的用户端为B，游戏为“所生成的数字为1～99，猜测所生成的数字是否大于50”，a的游戏信息为“猜测为是”，b的游戏信息为“猜测为否”，以当前用户端为A为例；
在步骤S32中，A向数据转发服务器发送第一游戏信息“猜测为是”，数据转发服务器将第一游戏信息转发给B(同理，B向数据转发服务器发送第二游戏信息“猜测为否”，数据转发服务器将第二游戏信息转发给A)；
在步骤S33中，A接收数据转发服务器转发的“猜测为否”(同理，B接收数据转发服务器转发的“猜测为是”)；
在步骤S34中，游戏开局后，A根据图1所示的随机数生成方法生成第三随机数，根据第三随机数生成第一游戏结果(同理，B根据图1所示的随机数生成方法生成第三随机数，根据第三随机数生成第一游戏结果)；
在步骤S35中，假设第一游戏结果为40，则a猜测正确，b猜测错误，B响应于b结算游戏，根据40生成第一链下交易并发送至数据转发服务器，数据转发服务器将第一链下结算交易转发给A。
图6为图5所示方法的一种优选实施方式的流程图。如图6所示，在一优选实施例中，步骤S35后还包括：
S36：响应于当前用户对第一用户提交的游戏结果进行申诉，生成第一维权交易并发送至数据转发服务器，以供数据转发服务器将第一维权交易发送至区块链节点，以供区块链节点执行第一维权交易，若申诉成功则罚没第一用户的若干资产。
由于第一游戏结果为40，a猜测正确，b猜测错误，B应该根据40生成第一链下交易并通过数据转发服务器转发给A；若未能及时接收到第一链下交易，a认为b存在不诚实的游戏行为；
具体地，区块链节点上配置了与用户端相同的游戏程序，假设第一维权交易包括a的游戏信息、b的游戏信息、rand(a)、hash(rand(a))、rand(b)、hash(rand(b))；
在步骤S36中，A响应于a对b提交的游戏结果进行申诉，生成第一维权交易并发送至数据转发服务器，数据转发服务器将第一维权交易发送至区块链节点，区块链节点执行第一维权交易：
区块链节点根据hash(rand(a))验证rand(a)，根据hash(rand(b))验证rand(b)，若均验证成功，则根据hash(rand(a))、hash(rand(b))生成第三随机数rand(M)；区块链节点根据上述游戏程序，以及rand(M)生成第一游戏结果为40；由于第一游戏结果为40，a的游戏信息为“猜测为是”，b的游戏信息为“猜测为否”，区块链节点判断b存在不诚实行为，即判断申诉成功，罚没b的若干资产。
在更多实施例中，若区块链上已记录有第三随机数rand(M)，则第一维权交易包括a的游戏信息、b的游戏信息；区块链节点根据上述游戏程序，以及rand(M)生成第一游戏结果为40；由于第一游戏结果为40，a的游戏信息为“猜测为是”，b的游戏信息为“猜测为否”，区块链节点判断b存在不诚实行为，即判断申诉成功，罚没b的若干资产；若区块链上已记录有第三随机数rand(M)，则第一维权交易包括a的游戏信息、b的游戏信息可实现相同的技术效果。
图7为本发明一实施例提供的另一种游戏方法的流程图。如图7所示，本发明提供一种适用于数据转发服务器的游戏方法，上述方法包括：
S42：接收游戏信息，将游戏信息转发给第一通道内的各其它用户端；
S44：接收链下结算交易，将链下结算交易转发给第一通道内的各其它用户端；其中，链下结算交易由第一用户端响应于第一用户结算游戏并根据第一游戏结果所生成，第一游戏结果由第一随机数所生成，第一随机数由游戏开局后根据如图3所示的随机数生成方法所生成。
上述实施例的随机数生成原理可参考图5所示的方法，此处不再赘述。
图8为图7所示方法的一种优选实施方式的流程图。如图8所示，在一优选实施例中，S44后还包括：
S46：接收第一维权交易，将第一维权交易发送至区块链节点，以 供区块链节点执行第一维权交易，若申诉成功则罚没第一用户的若干资产；其中，第一维权交易由第一用户端响应于第一用户对第二用户提交的游戏结果进行申诉所生成。
