 本发明的实施方式
本申请实施例提供的基于共识协议的信息处理方法（为方便描述，可简称本申请实施例提供的方法）可适用于各个领域、各个行业中的各个企业的区块链网络，也可适用于基于共识协议实现信息处理的信息系统等，在此不做限制。为方便描述，下面可以某一个领域和/或某一个行业中的某一个区块链网络为例，对本申请实施例提供的方法进行描述。区块链网络具体可指一个由各节点通过共识协议达成的、具有分布式数据存储结构的网络系统，且根据具体的共识协议的不同，达成全部或部分节点的信息全备份。由于区块链网络在相应共识协议下运行，区块链网络与相应共识协议之间存在既定的配置联系，因此为了基于共识协议能够实现对某些特定信息的拦截，故可通过向共识协议中添加拦截标识信息以使共识协议能够确定出需要拦截的信息，进而对需要拦截的信息进行拦截。其中，上述共识协议包括但不限于工作量证明机制（Proof of Work，PoW）、权益证明机制（Proof of Stake，PoS）、股份授权证明机制（Delegated Proof of Stake, DPoS）、实用拜占庭机制（Practical Byzantine Fault Tolerance，PBFT）以及Ripple共识算法，在此不做限制。
下面将结合图1至图4对本申请实施例提供的方法及相关装置进行说明。参见图1，图1是本申请实施例提供的基于共识协议的信息处理方法的一流程示意图。本申请实施例提供的方法可包括如下步骤101-104。
101、接收信息管理方发送的信息添加指令。
在一些可行的实施方式中，在向共识协议中添加的拦截标识信息之前，区块链网络中的区块链节点可先接收信息管理方发送的信息添加指令。其中，上述信息添加指令中携带有拦截标识信息，上述拦截标识信息用于确定接收到的信息是否属于待拦截信息类型。例如，当区块链节点接收到信息管理方发送的信息添加指令中携带的拦截标识信息为“虚拟账户”，并将拦截标识信息“虚拟账户”添加至共识协议后，共识协议可基于拦截标识信息“虚拟账户”判断区块链节点接收到的信息是否携带有“虚拟账户”信息。当区块链节点接收到的信息中包含有“虚拟账户”信息时，可将区块链节点接收到的信息确定为待拦截信息类型，也就是说此时区块链节点需要对此时接收到的信息进行拦截。其中，上述信息管理方可以是区块链网络的管理设备，也可以是共识协议的开发终端等，在此不做限制。
在一些可行的实施方式中，为了保证信息管理方将上述信息添加指令发送至区块链节点的过程中，上述信息添加指令的指令信息不被篡改，因此信息管理方在生成信息添加指令之后，可对上述信息添加指令信息进行加密处理。例如，信息管理方可采用区块链网络的公钥对上述信息添加指令进行加密得到上述信息添加指令对应的密文信息，并将所述密文信息发送至区块链节点。再例如，信息管理方可对上述信息添加指令进行哈希运算，得到上述信息添加指令的唯一摘要信息。同时采用信息管理方的私钥对上述唯一摘要信息进行加密以得到上述信息添加指令的数字签名，并将上述数字签名与上述信息添加指令的密文信息一起发送至区块链节点。其中，上述唯一摘要信息是将上述信息添加指令进行哈希运算后得到的一个固定长度的唯一的字符串，该字符串的具体表现形式在此不做限制。
在一些可行的实施方式中，区块链节点在接收信息管理方发送的信息添加指令之前，为了防止接收到错误指令或者接收到被篡改的指令，可对上述信息添加指令进行指令有效性验证。当信息管理方将采用区块链网卡的公钥对上述信息添加指令进行加密得到的密文信息发送至区块链节点时，若区块链节点采用区块链网络的私钥对上述密文信息成功解密，则证明上述密文信息没有被篡改，也就是说上述信息添加指令为有效指令。当区块链节点在接收到上述密文信息的同时也接收到上述信息添加指令对应的数字签名时，可采用区块链网络的私钥对上述密文信息进行解密，得到信息添加指令。在通过对上述密文信息进行解密得到信息添加指令之后，对该信息添加指令进行哈希运算得到该信息添加指令对应的实际唯一摘要信息。同时，采用信息管理方的公钥对接收到的数字签名进行解密，得到信息管理方发送的信息添加指令对应的唯一摘要信息。将上述实际唯一摘要信息与上述唯一摘要信息进行对比，如果两者信息一致，则证明上述密文信息和上述数字签名没有被篡改，也就是说上述信息添加指令为有效指令。可选的，在对上述密文信息和/或上述数字签名进行解密之前，也可先判断上述信息管理方发送的信息添加指令中是否包含区块链节点的身份标识。如果上述信息添加指令中不包含区块链节点的身份标识，则说明上述信息添加指令不是发送至区块链节点的指令信息，此时区块链节点不对上述信息添加指令做任何处理。相反，如果上述信息添加指令中包含区块链节点的身份标识，则证明上述信息添加指令时发送至区块链节点的指令信息，此时区块链节点可对上述信息添加指令进行指令有效性验证。其中，上述身份标识可以是特定的数字、字母以及字符的一种或多种组合，具体表现形式在此不做限制。需要特别说明的是，验证上述信息添加指令中是否包括区块链节点的身份标识信息的过程可根据实际应用场景确定，在此不做限制。
102、当上述信息添加指令为有效指令时，响应上述信息添加指令并将上述拦截标识信息添加至上述第一共识协议中以得到第二共识协议。
在一些可行的实施方式中，由于现有的共识协议都是以固定且不可修改的形式配置与区块链网络中，仅根据不同的应用场景采用不同的共识协议对信息进行处理。因此，当上述信息添加指令为有效指令时，可响应上述信息添加指令并将上述信息添加指令中携带的拦截标识信息添加至第一共识协议中得到第二共识协议，以使上述第二共识协议能够识别区块链节点接收到的信息中是否包含上诉拦截标识信息。其中，上述第一共识协议可以为在特定应用场景下对应的共识协议，上述第二共识协议为在上述第一共识协议基础之上添加了拦截标识信息之后生成的具备识别出拦截标识信息能力的新的共识协议。需要特别说明的是，上述第二共识协议与上述第一共识协议的区别仅限于上述第二共识协议可识别出区块链节点接收的信息中是否包含上述拦截标识信息，第二共识协议与第一共识协议部署于区块链网络上的配置信息等完全一致，在此不再赘述。
在一些可行的实施方式中，在将上述信息添加指令中携带的拦截标识信息添加至上述第一共识协议中时，可在更新上述第一共识协议的过程中通过向上述第一共识协议中增加识别拦截标识信息的命令，以达到在不影响上述第一共识协议原功能的情况下在上述第一共识协议中添加拦截标识信息的识别功能，并将添加识别功能后的第一共识协议确定为第二共识协议。或者，可选的，可将识别上述拦截标识信息的功能生成识别功能脚本并将该识别功能脚本部署于上述第一共识协议中以得到第二共识协议。当基于上述第二共识协议识别区块链节点接收到的任一信息中是否包含上述拦截标识信息时，上述第二共识协议通过上述识别功能脚本的脚本路径，调用上述识别功能脚本以识别区块链节点接收到的信息中是否包含上述拦截标识信息。需要特别说明的是，上述识别拦截标识信息的命令和上述识别功能脚本中均包含上述拦截标识信息，且包含的拦截标识信息可作为具体识别过程中的识别依据。同时，在将上述信息添加指令中携带的拦截标识信息添加至上述第一共识协议中的具体方式包括但不限于上述所示的实现方式，具体可根据实际应用场景确定，在此不做限制。
103、当接收到信息发送方发送的待处理信息时，基于上述第二共识协议确定上述待处理信息是否属于待拦截信息类型。
在一些可行的实施方式中，在得到上述第二共识协议之后，当区块链节点接收到信息发送方发送的待处理信息时，区块链节点可通过上述第二共识协议判断上述待处理信息中是否包含上述拦截标识信息。其中，上述信息发送方包括但不限于交易发起平台、身份验证平台、用户管理平台以及产品供应方等，在此不做限制。若上述待处理信息中包含上述拦截标识信息，则确定上述待处理信息属于上述待拦截信息类型。若上述待处理信息中不包含上述拦截标识信息，则确定上述待处理信息不属于上述待拦截信息类型。需要特别说明的是，由于上述待处理信息有多种信息来源，因此当信息发送方将上述待处理信息发送至区块链节点时，上述待处理信息的信息表现形式可能与上述第二共识协议中的拦截标识信息的信息表现性质不一致。例如，当上述拦截标识信息为二进制字符串时，上述信息发送方发送的待处理信息可能为数字与字母的组合形式，两种信息表现形式无法进行比较识别，此时上述第二共识协议不能基于上述拦截标识信息确定上述待处理信息是否属于待拦截信息类型。因此，当区块链节点接收到信息发送方发送的待处理信息时，可判断上述待处理信息的信息表现形式与上述第二共识协议中的拦截标识信息的信息表现形式是否一致，若一致，则基于上述第二共识协议确定上述待处理信息是否属于待拦截信息。若不一致，则可对上述拦截标识信息或者上述待处理信息进行信息处理以使上述拦截标识信息与上述待处理信息的信息表现形式一致，进而基于上述第二共识协议确定上述待处理信息是否属于待拦截信息。
在一些可行的实施方式中，在基于上述第二共识协议确定上述待处理信息是否属于待拦截信息类型时，可基于上述第二共识协议中的拦截标识信息从预设信息库中确定出与上述拦截标识信息语义一致，且属于上述待拦截信息类型的至少一个目标信息。其中，上述预设信息库中的信息可以是基于互联网、数据库或者其他存储空间中获取的常见拦截信息，也可以是由信息发送方、信息接收方以及信息管理方预先指定的拦截信息，具体来源不做限制。当区块链节点接收到信息发送方发送的待处理信息后，可确定上述待处理信息中是否包含上述至少一个目标信息中的任一目标信息，当上述待处理信息中包括上述任一目标信息，则确定上述待处理信息属于上述待拦截信息类型。当上述待处理信息中不包含上述至少一个目标信息中的任何目标信息时，可确定上述待处理信息不属于上述待拦截信息类型。在基于预设信息库中的至少一个目标信息来确定上述待处理信息是否属于上述待拦截信息类型时，多个目标信息可扩大上述待拦截信息类型的范围，从而提升确定上述待处理信息是否属于待拦截信息类型的准确度和全面性，适用性更高。
104、当上述待处理信息属于上述待拦截信息类型时，基于上述第二共识协议拦截上述待处理信息。
在一些可行的实施方式中，当基于上述第二共识协议确定信息发送方发送的待处理信息属于上述待拦截信息类型时，可基于上述第二共识协议拦截上述待处理信息。可选的，在具体的待处理信息拦截过程中，上述第二共识协议可选择不对上述待处理信息进行验证。也就是说，当上述待处理信息属于上述待拦截信息类型时，即使区块链节点接收到上述待处理信息，由于上述第二共识协议不对上述待处理信息进行验证，因此上述待处理信息在未得到第二共识协议的验证的情况下，区块链节点不会将上述待处理信息写入区块链，也不会通过区块链网络将上述待处理信息发送至任一信息接收方，从而达到拦截上述待处理信息的目的。在上述第二共识协议拒绝对上述待处理信息进行验证的情况下，区块链节点可删除上述待处理信息以降低区块链网络资源消耗。可选的，区块链节点在删除上述待处理信息之后，或者在上述第二共识协议拒绝对上述待处理信息进行验证的情况下，可生成拒绝指令并将该拒绝指令发送至上述信息发送方。其中上述拒绝指令可以是数字、字母以及其他符号的一种或多种组合序列，在此不做限制。此外，当上述拒绝指令中包含有修改指示信息时，上述信息发送方可在接收到上述拒绝指令之后，根据上述拒绝指令中修改指示信息来修改上述被拦截的待处理信息，并将修改后的待处理信息重新发送至区块链节点。
在一些可行的实施方式中，当上述待处理信息不属于上述待拦截信息类型时，可基于上述第一共识协议和或者上述第二共识协议中的既定协议内容对上述待处理信息进行验证。例如，当上述第一共识协议和上述的第二共识协议PoW机制时，可基于上述待处理信息中所指示的工作量为上述信息发送方提供相应的报酬。当上述第一共识协议和上述第二共识协议为重要程度证明机制时，可基于上述待处理信息中所指示的信息发送方的重要程度来分配相关资源。当区块链节点基于上述第一共识协议或者上述第二共识协议对上述待处理信息进行验证处理之后，可将得到的结果信息写入区块链网络中进而通过区块链网络将上述结果信息发送至与区块链网络连接的各信息接收方，其中，上述信息接收方包括但不限于账户管理平台、数据结算平台以及信息发布平台等，在此不做限制。
由于在将拦截标识信息添加至上述第一共识协议得到上述第二共识协议之后，上述第二共识协议会一直确定区块链节点接收到的任何待处理信息是否属于待拦截信息类型，因此当不需要拦截包含上述拦截标识信息的待处理信息时，需要删除上述第二共识协议中的拦截标识信息。请参见图2，图2是本申请实施例提供的基于共识协议的信息处理方法的另一流程示意图。本申请实施例提供的基于共识协议的信息处理方法的另一流程示意图中包括如下步骤201-203。
201、接收信息管理方发送的信息删除指令。
在一些可行的实施方式中，当不需要拦截包含上述拦截标识信息的待处理信息时，可接收信息管理方发送的信息删除指令。其中，由于上述第二共识协议中可能包含多个拦截标识信息，因此上述信息删除指令中需要包含具体的拦截标识信息以删除上述第二共识协议中对应的拦截标识信息。例如，当区块链节点将多个拦截标识信息“虚拟账户”、“密码”添加至上述第一共识协议得到第二共识协议后，基于上述第二共识协议可拦截包含有“虚拟账户”、“密码”信息的待处理信息。当不需要拦截包含有“虚拟账户”信息的待处理信息时，信息管理方可生成包含有“虚拟账户”信息的信息删除指令以删除上述第二共识协议中的拦截标识信息“虚拟账户”。需要特别说明的是，当信息管理方生成上述信息删除指令时，可对上述信息删除指令进行加密处理，具体实现方式可参见步骤101中所示，在此不再赘述。
202、当上述信息删除指令为有效指令时，响应上述信息删除指令并删除第二共识协议中的拦截信息标识以得到第三共识协议。
在一些可行的实施方式中，在信息管理方生成信息删除指令并将上述信息删除指令发送至区块链节点后，区块链节点可对上述信息删除指令的身份标识和/或指令有效性进行验证，具体实现方式可参见步骤101中所示，在此不再赘述。当上述信息删除指令为有效指令时，区块链节点可响应上述信息删除指令并基于上述信息删除指令中所包含的拦截标识信息删除上述第二共识协议中对应的拦截标识信息，进而得到第三共识协议。例如，当上述第二共识协议中包含拦截标识信息“虚拟账户”、“密码”，也就是说在基于上述第二共识协议拦截包含有“虚拟账户”、“密码”信息的待处理信息时，如果上述信息删除指令中包含有“虚拟账户”信息时，可删除上述第二共识协议中的拦截标识信息“虚拟账户”。在此基础上得到的第三共识协议中只包含拦截标识信息“密码”，也就是说此时上述第三共识协议只拦截包含有“密码”信息的待处理信息，不再对包含“虚拟账户”信息的待处理信息进行拦截。
203、当接收到信息发送方发送的待处理信息时，基于上述第三共识协议对上述待处理信息进行处理。
在一些可行的实施方式中，由于区块链节点在响应上述信息删除指令并删除上述第二共识协议中与所述信息删除指令对应的拦截标识信息之后，得到的第三共实现协议中可能还包括至少一个其他拦截标识信息。因此，此时接收到信息管理方发送的待处理信息之后，可基于上述第三共识协议中的拦截标识信息对上述待处理信息进行拦截。或者当删除上述第二共识协议中唯一的拦截标识信息时，可基于此时得到的第三共识协议或者上述第一共识协议对上述待处理信息进行处理，具体处理方式可参见步骤104中所示，在此不再赘述。
在本申请实施例中，在将信息添加指令中携带的拦截标识信息添加至共识协议后可得到具备确定接收到的信息是否属于待拦截信息类型的共识协议。当接收到信息发送方发送的待处理信息时，可基于新的共识协议拦截属于待拦截信息类型的待处理信息，进而提升信息处理水平。同时，通过信息删除指令可删除共识协议中的拦截标识信息，从而灵活调整待拦截信息类型，灵活性强，适用性更高。
