具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
目前，线上平台可定期或不定期地在平台上举办推广活动，如艺术作品的投票评优活动等；然而，线上平台都需要主办方参与投票过程，即目前的投票系统都采用中心化方式，这样会引起投票过程不公开透明，容易滋生舞弊、作弊等行为，导致投票结果不可信和缺乏安全性。
为解决上述问题，本公开实施例提供了一种分布式投票方法，图1是本公开实施例示出的分布式投票方法的一种流程图。本公开实施例提供的分布式投票方法可以应用于多个区块链设备构成的分布式投票系统，每个区块链设备构成系统中的一个节点。由于每个节点的地位是平等的，因此各节点可以在验票节点、投票节点和参赛节点三个角色中互转，或者同时扮演两个或三个角色。其中，参赛节点，是指共同发起投票活动或者响应投票活动且上传投票对象的节点；投票节点，是指响应投票活动且为投票对象进行投票的节点；验票节点，是指将投票交易写入分布式投票系统的节点。
需要说明的是，本实施例中投票活动可以由云平台(服务器)发起，也可以由多个参赛节点共同发起。
例如，由云平台发起投票活动时，用户通过分布式投票系统中任意一个节点进入系统以查阅到该投票活动，然后各节点可以响应该投票活动上传相应的投票对象，这些节点成为参赛节点。同时，分布式投票系统中的各节点可以欣赏投票对象，并响应投票活动为各投票对象进行投票，这些节点成为投票节点。具体投票或验证内容参考后续实施例，在此先不作赘述。
又如，由多个参赛节点共同发起投票活动时，分布式投票系统中的一个节点可以通过系统发起投票活动邀请，系统中的其他节点可以接受该投票活动邀请，当参赛节点的数量达到一定数量，例如3-5个，该投票活动生效，这些节点成为参赛节点，并且系统提示各参赛节点上传投票对象。之后，系统中各节点可以作为投票节点为投票对象进行投票，并且系统中各节点可以作为验票节点来验证投票节点的投票请求，具体内容参考后续实施例，在此先不作赘述。
为方便描述，本公开实施例以分布式投票系统为线上艺术画廊、投票对象为艺术作品，且以线上艺术画廊中各节点为某一件或者几件艺术作品投票的场景为例对本公开实施例提供的分布式投票方法进行描述，但是该场景不构成对本申请的限定。如图1所示，分布式投票方法可包括步骤101和步骤102。
在步骤101中，分布式投票系统中的验票节点监测到系统中的投票节点广播的投票承诺信息，根据预先获取的投票节点的公钥信息以及该投票承诺信息的签名信息，确定该投票承诺信息有效。
其中，投票承诺信息是投票节点根据参赛节点广播的投票邀约信息生成的，投票承诺信息包括投票节点的标识信息、投票对象的标识信息、投票时间信息，以及投票节点根据自身的秘钥为投票承诺信息生成的签名信息。投票节点的秘钥与投票节点的公钥唯一对应。
根据本公开实施例，在参赛节点上传艺术作品(投票对象)之后，用户可以通过系统中的节点欣赏艺术作品，还可以针对该艺术作品响应投票活动。参赛节点可以将投票邀约信息广播至系统中的其他节点。投票邀约信息可包括参赛节点标识以及艺术作品的标识信息等投票活动的相关内容(后文称之为参赛数据)。系统中的其它节点可以响应于投票活动，作为投票节点为该艺术作品投票。投票节点可以针对参赛节点生成投票承诺信息(后文称之为投票数据)。
根据本公开实施例，艺术作品中可包括摄影作品、绘画作品、文学作品或影视作品，甚至在设备终端播放显示的艺术形式皆可，在此不做限制。
根据本公开实施例，如图2所示，投票节点根据参赛数据，生 成投票数据，可具体包括步骤201-步骤203。
在步骤201中，投票节点向参赛节点发起投票请求信息，参赛节点默认同意该投票请求。
在步骤202中，投票节点生成针对参赛节点的投票承诺。例如，投票节点生成随机字符串作为投票承诺，记作：P＝TvoteC，其中，P为投票承诺，T表示投票节点的标识信息，C表示参赛节点的标识信息或艺术作品的标识信息。
在步骤203中，投票节点利用自身私钥签名投票承诺，生成投票数据。投票数据的格式可如下：
S＝Sign(Pri TC，P/T timestamp)；
其中，S表示投票数据，Pri TC表示投票节点的私钥，P/T timestamp表示时间戳，即投票时间信息(形成交易的时间)。
根据本公开实施例，在云平台(服务器)或者多个参赛节点发起投票活动之后，系统可为每个节点(或每个节点对应的用户)随机生成一对公钥和私钥。在投票节点向参赛节点发起投票请求信息之前，投票节点可将自身的标识信息与公钥进行绑定生成公钥证书(公钥信息)，并将公钥证书发布至系统，以由系统中的其它节点(验票节点)获取该投票节点的公钥证书，并根据该投票节点的公钥证书对该投票节点广播的投票数据进行验证。
实施例，在投票节点将投票数据广播至系统中的其他节点之后，此时监测到投票数据的节点可以作为验票节点。验票节点可以采用不对称加密算法验证投票数据是否有效。在一种实施方式中，验票节点可根据预先获取的该投票节点的公钥证书以及该投票数据的签名信息，确定该投票数据由该投票节点编辑生成。
根据本公开实施例，验票节点还可根据投票节点的标识信息以及系统中存储的历史投票记录，确定投票节点对应的账户余额是否超过投票额。投票额为投票节点为本次投票需要支付给参赛节点的数额。
根据本公开实施例，在投票数据由投票节点编辑，以及投票节点的账户中余额超过投票额的情况下，验票节点确定该投票数据为有效的投票数据。否则为无效的投票数据。当然，本领域技术人员还可 以根据具体场景，调整验证条件以达到判断投票数据是否有效数据的目的，同样可以实现本申请的方案。
根据本公开实施例，由于将每个投票行为(投票数据)作为一次投票交易，验票节点可以在接收到投票交易后作如下校验：首先，验证投票交易在系统之中是否可靠，验票节点会针对每个前序交易的输出运行核验脚本，确保返回结果为真。第二，检查是否存在双重支付。第三，检查节点是否已经接收过此投票交易。第四，节点只接收和传递在白名单上的标准脚本。具体校验方式可以参见相关技术在此不作限定。
在步骤102中，验票节点根据投票承诺信息生成投票记录，并将投票记录存储在系统的当前数据块。
本实施例中将投票节点生成投票数据的过程，视为一次投票交易，并且预先写入智能合约。在投票数据有效的情况下，验票节点可以触发智能合约生效。智能合约的内容为将投票节点与参赛节点之间的投票交易(投票记录)写入当前数据块。
根据本公开实施例，投票交易写入当前数据块之后，投票节点可根据投票额减少投票节点对应的账户余额；即，完成交易后，投票节点对应的账户余额减少一个投票额。相应地，参赛节点可根据投票额增加参赛对应的账户余额并更新艺术作品的得票结果；即，完成交易后，被投票的参赛节点对应的账户余额相应增加一个投票额，并且艺术作品的得票结果也随之改变。
根据本公开实施例，系统的当前数据块可以是通过以下方式获得的：验票节点确定使得第一预设算法的输出值满足设定条件的输入值；验票节点根据输出值、以及系统中最近生成的数据块的标识信息，生成该当前数据块；以及，验票节点广播输入值、输出值以及该当前数据块的标识信息，以使得系统中的其它节点根据输入值、输出值以及第一预设算法，确认该当前数据块的标识信息对应的该当前数据块生成。
至此本实施例中通过将投票节点的投票交易写入区块链系统，这样系统中的所有节点可以查阅投票信息，从而增加投票过程的透明 度，可以提升投票过程的可信度。并且，本实施例中，将投票过程作为一次交易写入当前数据块后，不可以篡改，有利于提高投票过程的安全性。
根据本公开实施例，当线上艺术画廊发起投票活动或者多个参赛节点共同发起投票活动时，线上艺术画廊为系统中各节点的账户中增加第一设定数值，或者为各投票节点的账户中增加第一设定数据。例如，系统中的节点A准备为参赛节点投票时，线上艺术画廊中为节点A的账户中分配3个投票币，从而方便节点A进行投票。这样，通过为投票节点分配投票币，可方便投票节点在投票过程中向参赛节点支付一定数量的投票额，例如1个投票币，即将投票节点向参赛节点支付投票币的支付交易作为一次投票交易。
根据本公开实施例，在用户注册时，线上艺术画廊可根据预先设置的算法直接向该用户的账户中增加第二设定数值；即，该用户可以参加第二设定数值次的投票活动，之后则需要由用户充值，以及参与验票或者创建数据块来获取奖励，利用该奖励来继续参与投票活动。
根据本公开实施例，验票节点还可响应于系统中的其它节点确认当前数据块生成，根据第三设定数值增加验票节点对应的账户余额。由于在分布式系统中，节点越多，数据链越稳定；因此，为了让投票系统更加稳定，则需要更多的节点参与，即需要更多的验证投票行为，将投票记录打包进数据块加入系统中。但是验票节点并不会做义务的劳动，因此，分布式投票系统可建立奖励机制，验票节点竞争验票。例如，验票节点每新生成一个新的数据块，奖励100枚艺术币，该艺术币可以在线上艺术画廊中使用，用来购买数字画作或用于其他交易行为。
根据本公开实施例，奖励机制使得验票节点有动力验证及记录投票行为，越来越多的验票节点加入，也使得区块链结构更稳定，同时，由于投票行为的增加，数据块数增加，区块链增长，使得区块链中记载的投票行为更难以被篡改，而由于每个节点都能看到区块链的整个账本，使得投票过程更为公开和透明。
根据本公开实施例，当线上艺术画廊发起例如艺术作品评优活 动的投票活动之后，各参赛节点在上传艺术作品的同时或之后，还可请求对艺术作品进行版权登记；系统中的其它节点还可作为登记节点，对艺术作品进行版权登记。如图3所示，版权登记的方法可包括步骤301-步骤302。
在步骤301中，参赛节点广播版权登记请求信息，版权登记请求信息包括艺术作品的数字内容标识。
根据本公开实施例，参赛节点可基于第二预设算法以及艺术作品的内容信息，生成艺术作品的内容标识；以及基于第三预设算法、艺术作品的内容标识以及艺术作品的版权所有人标识信息，生成数字内容标识。
在实施中，艺术作品的版权所有人标识信息为参赛节点的公钥。
在步骤302中，登记节点响应于接收到版权登记请求信息，确定数字内容标识为系统中的唯一值；以及，根据版权登记请求信息生成艺术作品的版权登记记录，并将版权登记记录存储在系统中。
根据本公开实施例，登记节点在确定数字内容标识为系统中的唯一值之前，还可确定版权登记请求信息还包括艺术作品的版权所有人身份信息，艺术作品的权利声明信息，艺术作品的作者身份信息以及艺术作品的版权所有人地址信息中的至少一个。即，登记节点验证版权登记请求信息中的信息完整。
根据本公开实施例，版权登记请求信息还可包括参赛节点根据自身的秘钥为版权登记请求信息生成的签名信息；则在步骤在步骤302中，登记节点根据版权登记请求信息生成艺术作品的版权登记记录之前，登记还可根据预先获取的参赛节点的公钥信息以及版权登记请求信息的签名信息，确定版权登记请求信息由该参赛节点编辑生成；其中，参赛节点的秘钥与参赛节点的公钥唯一对应。
结合具体实例对本公开实施例中的分布式投票方法进行详细说明。
如图4所示，其为本公开实施例中的分布式投票方法的又一种流程图，该分布式投票方法可包括步骤401～步骤405。
在步骤401中，区块链中的验票节点监测到区块链中的投票节 点发起投票数据时，验证投票数据是否有效；该投票数据由投票节点针对参赛节点编辑。
步骤401和步骤101的具体实施方法和实施原理一致，详细描述请参考图1及步骤101的相关内容，此处不再赘述。
在步骤402中，区块链中各节点尝试寻找与当前数据块的随机散列值相匹配的随机数，以创建当前数据块。
为保证区块链的数据稳定可靠，需要尽可能的增加区块链中的节点数量，因此，在实施中，需要更多的区块链设备参与验证投票，将投票交易写入区块链。
在实施中，区块链中各节点尝试寻找一个随机数(Nounce)，该随机数与当前数据块的随机散列值相匹配。经过多次尝试，区块链中一个节点可以找到一个随机数满足上述要求，从而获取到创建一个区块(Block)即当前数据块的权利。该节点将找到正确随机数的事件广播至区块链中的其他节点。
在步骤403中，若检测到有节点创建当前数据块，则除创建该当前数据块的节点之外的其他节点检验该当前数据块是否满足预先设置的工作量证明共识机制。
本在实施中，当区块链中的其他节点检测到有节点创建当前数据块后，则验证当前数据块是否满足预先设置的工作量证明(Proof of Work，POW)共识机制。其中，POW共识机制可以根据相关技术中的方案实现，在此不作限定。
在步骤404中，若满足，则除创建该当前数据块的节点之外的其他节点信任并接纳该当前数据块。
在实施中，若当前数据块满足POW共识机制，则其他节点确定当前数据块是经过该节点的诚实劳动得到的，从而信任并接纳当前数据块。否则，不信任该当前数据块。
为使区块链中各节点有动力参与验票，在实施中，线上艺术画廊中可以预先设置算法，为创建当前数据块的节点的账户中增加第二数值。例如，在某个验票节点先找到随机数时，线上艺术画廊允许该验票节点将此段时间内的交易记录在区块中。同时，此段时间内的交 易中还包括一个特殊交易即奖励，该特殊交易的输入内容为空，输出内容为第一个找到随机数的验票节点的地址，这样线上艺术画廊可以为创建当前数据块的节点的账户奖励，比如100枚艺术币。之后，该节点的用户可以在线上艺术画廊中进行欣赏艺术作品，购买艺术作品的所有权或者其他交易行为。
可见，根据本公开实施例，通过奖励机制可以吸引越来越多的区块链节点参与验票和建立新区块，这样可以保证区块链结构更稳定。同时，由于投票行为的增加以及区块数增加，可以使区块链增长，进而使得区块链中记载的投票数据更难以被篡改。
需要说明的是，在实施中，步骤402～步骤404与步骤401的执行顺序不作限定，即步骤402～步骤404可以先于或者后于步骤401，还可以与步骤401同时执行，本实施例不作限定。
在步骤405中，若投票数据有效，则智能合约生效，该智能合约的内容为将投票节点与参赛节点之间的投票交易写入当前数据块。
步骤405和步骤102的具体实施方法和实施原理一致，详细描述请参考图1及步骤102的相关内容，此处不再赘述。
至此根据本公开实施例，通过设置奖励机制，可以吸引更多的区块链节点加入验票和建立新区块，这样可以保证区块链增长，且保证投票数据不被篡改，提升投票过程的安全性。并且，区块链中各节点将投票节点的投票交易写入区块链，这样区块链中的所有节点可以查阅投票信息，从而增加投票过程的透明度，可以提升投票过程的可信度。
如图5所示，其为本公开实施例中的分布式投票方法的再一种流程图，该分布式投票方法可包括步骤501～步骤505。
在步骤501中，参赛节点向区块链广播版权登记请求。
在实施中，在多个用户通过区块链设备(即参赛节点)共同发起投票活动或者线上艺术画廊发起投票活动时，用户可以通过相应的区块链设备上传艺术作品。在上传艺术作品的同时，用户可以通过版权登记请求明确艺术作品的归属，其中版权登记请求可以包括版权所有人的地址、版权所有人的身份信息、版权所有人的签名、版权声明、 艺术作品的数字内容标识中的一种或者多种。版权声明还可以包含数字内容的基本信息和/或艺术作品的权利状况说明。数字内容的基本信息包括数字内容概述和/或评价。
在实施中，版权所有人的签名，是指利用版权所有人的私钥对一段任意数字(例如：艺术作品的数字内容，艺术作品的数字内容标识)进行加密运算的结果。并且，通过公钥可以对签名进行验证，验证通过，则说明被签名的数字内容是由公钥所有者发布的和可信的；否则表示被签名的数据是伪造的和不可信的。私钥和公钥是一一对应的，在版权所有人注册在过程中生成，其长度可以是256位(bit)或者以上。
在实施中，版权所有人的地址，可以是预先生成的，当用户在线上艺术画廊中注册时，可以得到一个该版权所有人的地址。本实施例中，版权所有人的地址可以利用版权所有人的公钥生成，例如地址可以是版权所有人的公钥自身，也可以是根据一个hash算法，对版权所有人的公钥进行hash生成的公钥hash值，还可以是包含公钥的一段脚本等多种形式，并且保证是全网唯一。
在实施中，区块链设备利用预先设置的哈希算法对数字内容(即艺术作品)作哈希运算，得到数字内容哈希值。之后，区块链设备利用预先设置的哈希算法(或者另一个哈希算法)对数字内容哈希值和版权所有人标识信息(如，版权所有人的地址)作哈希运算，得到数字内容标识，即数字内容标识＝hash(数字内容hash值+版权所有人标识信息)。
在实施中，哈希算法可以为安全哈希算法(Secure Hash Algorithm，SHA1)或者信息-摘要算法5(Message-Digest Algorithm 5，MD5)。当然，技术人员还可以选择其他算法来替代哈希算法，在实现上述方案的情况下，相应的方案和算法同样落入本申请的保护范围。
在步骤502中，在版权登记请求通过校验后，区块链中的各节点根据该版权登记请求构造版权登记事务。
在实施中，如图6所示，区块链中各节点在接收到版权登记请 求后，对该版权登记请求进行校验，可包括步骤601-步骤603。
在步骤601中，区块链中各节点检测版权登记请求中的内容是否完整。
参见图7，区块链中各节点可以获取参赛节点广播的校验信息。其中检验信息至少包括数字内容、带有数字签名的字符串和公钥(对应步骤701)。然后，各节点基于预设的哈希算法对数字内容进行哈希运算，可以得到数字内容的第一哈希值(对应步骤702)。之后，各节点利用该节点的公钥解密带有数字签名的字符串，得到数字内容的第二哈希值(对应步骤703)。最后，各节点判断第一哈希值和第二哈希值是否相等，若第一哈希值和第二哈希值相等，则各节点确定版权登记请求中的内容完整(对应步骤704)，否则不完整。
在步骤602中，若完整，区块链中的各节点判断版权登记请求中的数字内容标识是否为区块链中的唯一值。
基于数字内容标识的计算公式，各节点可以得到版权登记请求对应的数字内容标识，各节点将校验信息中的数字内容标识与各自区块中的数字内容标识进行匹配，从而确定校验信息中的数字内容标识是否为唯一值。
在步骤603中，若是，则区块链中的各节点确定版权登记请求通过校验。
在实施中，若数字内容标识为唯一值，则各节点确定版权登记请求由广播该版权登记请求的节点编辑且是可信的，即各节点确定版权登记请求通过校验，这样可以保证版权登记的真实性、正确性和合法性。之后，区块链中的各节点可以根据版权登记请求，构造版权登记事务。构成版权登记事务的方案可以参考相关技术，在此不再赘述。
在步骤503中，区块链中的各节点将版权登记事务存储到区块链。
在实施中，区块链中的各节点可以将版权登记事务存储到区块链，这样该版权管理事务将很难被更改，进一步保证了版权管理事务的不可更改和时间证明的唯一性。
由于版权登记时，在区块链中还没有该版权的相关信息，即该 版权是新增的，因此本实施例中各节点将版权管理事务中包含的输入内容设置为空，输出内容设置为版权所有人的地址。这样，在版权登记后，区块链中记录了该艺术作品的版权是属于该版权所有人的。
在步骤504中，区块链中的验票节点监测到区块链中的投票节点发起投票数据时，验证投票数据是否有效；该投票数据由投票节点针对参赛节点编辑。
步骤504和图1中的步骤101的具体实施方法和实施原理一致，详细描述请参考图1及步骤101的相关内容，此处不再赘述。
在步骤505中，若投票数据有效，则智能合约生效，该智能合约的内容为将投票节点与参赛节点之间的投票交易写入当前数据块。
步骤505和图1中的步骤102的具体实施方法和实施原理一致，详细描述请参考图1及步骤102的相关内容，此处不再赘述。
根据本公开实施例，通过为艺术作品登记版权，并保证版权在区块链中唯一存在，防止艺术作品被抄袭，可以保证线上艺术画廊中艺术作品版权的公信力。并且，本实施例中区块链中各节点将投票节点的投票交易写入区块链，这样区块链中的所有节点可以查阅投票信息，从而增加投票过程的透明度，可以提升投票过程的可信度。
