背景技术
传统的区块链系统仅用于实现数据共享存储，无法实现参与者之间的信息交互。如果需要在区块链上进行信息交互，需要通信参与者之间建立一个专用于信息交互的数据通信通道，使得通信参与者在维护与区块链网络通信之外，还需要维护与所有其他通信参与者的数据通信通道。这种区块链的信息交互方式，增加了区块链系统的复杂性，加大了区块链系统的构建难度，并且在某些网络条件下是不可能实现的。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例1
图1示出本实施例中区块链上用户通信方法的一流程图。该区块链上用户通信方法可应用在以区块链为技术基础的应用系统上，用于进行区块链上任意两个用户之间的点对点通信。如图1所示，该区块链上用户通信方法包括如下步骤：
S10：以键值对方式创建区块链上每一用户的通信地址。
其中，键值(key-value)是一种数据存储方式，值指具体存储的数据，键即其存储的数据的索引，值可以通过查找其对应的键直接获取。键值反映的是一种数据存储的对应关系，由一个键及其对应的值所组成的数据关系对称为键值对。区块链是分布式数据存储、共识机制和加密算法等计算机技术的新型应用模式。本实施例是基于区块链系统实现的，即区块链应以区块链系统来理解。其中，区块链系统本质是一个去中心化的分布式数据库系统。需要说明的是，本实施例中区块链上的用户应理解为在区块链系统上的各个用户节点，即区块链系统上各个相关的终端，该终端可以是通过区块链网络相连的手机、电脑、平板和服务器等终端。
本实施例中，以键值对方式创建区块链上每一用户的通信地址，将区块链上每一用户 的通信地址作为存储的数据对应的索引，也即键值对中的键。通过为区块链上每一用户建立通信地址，能够实现根据区块链上用户的通信地址进行与该通信地址所对应的数据的修改和读取等操作，为后续实现区块链上任意两个用户之间的点对点通信提供了基础。
在一具体实施方式中，如图2所示，步骤S10中，以键值对方式创建区块链上每一用户的通信地址，具体包括如下步骤：
S11：以键值对方式创建区块链上每一用户的用户地址。
其中，用户地址是用于区分不同用户在区块链上的地址字段，任意两个用户的用户地址不相同。本实施例中，以键值对方式创建区块链上每一用户的用户地址，确定区块链上每一用户的地址字段。通过创建的区块链上每一用户的用户地址，可以以该用户地址为基础，设置多种不同功能的地址类型，如数据共享地址和通信地址等。
S12：根据用户地址，以键值对方式创建区块链上每一用户的通信地址，其中，区块链上每一用户的通信地址以键的形式存在，表示为地址前缀+用户地址。
本实施例中，区块链上每一用户的通信地址以键的形式存在，该通信地址对应的值即为通信地址中存储的数据。例如，可以把通信地址看成是用户的邮箱，该邮箱中存有与该邮箱唯一对应的数据即为键值对中的值。若通过键值对的方式实现数据存储时，用户的通信地址即为键，该键对应的值即为该通信地址存储的数据。
区块链上每一用户的通信地址以键的形式存在，具体可以表示为地址前缀+用户地址，其中，地址前缀用于区分该地址实现的功能的标识。例如，区块链上任意一个用户A的用户地址为userAAA，而该用户A的通信地址为MailuserAAA，则通信地址中的地址前缀为Mail，用于表示该地址是作为通信使用的邮箱地址。特别地，也可以不使用地址前缀+用户地址的方式表示通信地址，只要保证系统命名唯一即可，如用户A的通信地址也可以直接用用户地址userAAA进行表示。考虑到命名的规范性和合理性有利于区块链系统的合理设计和功能扩充，本实施例将区块链上每一用户的通信地址均表示为地址前缀+用户地址。
S20：用户A在用户B的通信地址对应的值Mb中写入键Kab，键Kab对应的值为Data1，用户A和用户B为区块链上任意选取的两个用户。
其中，用户A和用户B是区块链上任意选取的两个用户，这里的用户同样应理解为区块链系统上的终端，具体为通过区块链网络相连的终端。用户B的通信地址对应的值为Mb，键Kab和值Data1是一个键值对，这一键值对用于存储用户A在区块链上传送给用户B的数据。
本实施例中，区块链系统是一个去中心化的分布式数据库系统，拥有数据共享性以及 数据不可篡改性的特点，区块链上有任意两个用户：用户A和用户B。基于区块链系统，用户A在用户B的通信地址对应的值Mb中写入键Kab。该键Kab对应的值是Data1，即用户A想要用户B接收到的数据为Data1。其中，这里的写入操作具体为修改操作，通过修改操作将键Kab添加(写入)到值Mb中。通过在用户B的通信地址对应的值Mb写入键Kab，实现了将数据对应的键Kab写入到值Mb中，以使用户B可通过值Mb获取到A用户传送过来的数据(即键Kab对应的值为Data1)的目的，从而使得用户A与用户B在区块链上实现点对点通信。
在一具体实施方式中，如图3所示，步骤S20中，用户A在用户B的通信地址对应的值Mb中写入键Kab，键Kab对应的值为Data1，用户A和用户B为区块链上任意选取的两个用户，具体包括如下步骤：
S21：用户A以键值对方式向区块链上写入键Kab和与键Kab对应的值Data1，其中，键Kab＝数据前缀+用户B的用户地址+用户A的用户地址。
其中，数据前缀与地址前缀类似，数据前缀是用来区分数据的标识，数据前缀可以用时间戳加上用途标识来表示。例如，可以采用时间戳和Commu(即Communication的缩写)这一用途标识作为键Kab的数据前缀，表示该键Kab建立的时间以及该键的用途(这里指该键用于通信)。在确定数据前缀后，可将该数据前缀结合用户B的用户地址和用户A的用户地址，以唯一确定键Kab。可以理解地，数据前缀也可以采用其他方式表示(如直接使用Commu而无需携带时间戳，用于表示该数据用于通信)，只要能唯一区分该数据前缀代表的键即可。
本实施例中，在区块链系统上，用户A以键值对方式向区块链上写入键Kab和与键Kab对应的值Data1。其中，若键Kab是首次写入区块链系统，则该写入操作具体为创建操作；若键Kab已存在且用户A仍想继续使用该键Kab，则该写入操作具体为修改操作，不对键Kab作更改，修改键Kab对应的值Data1。其中，键Kab具体可以表示为键Kab＝数据前缀+用户B的用户地址+用户A的用户地址，也可以表示为键Kab＝数据前缀+用户A的用户地址+用户B的用户地址，键Kab还可以表示为其他方式，只要满足用户A能够将键Kab写入到值Mb中且用户B可以根据自身的通信地址获取到键Kab即可。
S22：用户A在区块链上读取用户B的通信地址，根据用户B的通信地址获取对应的值Mb。
本实施例中，用户A在区块链上读取用户B的通信地址，当用户B的通信地址表示为键MailUserBBB时，用户A在区块链上读取用户B的通信地址即为键MailUserBBB。由于 用户B的通信地址和对应的值Mb是以键值对方式进行存储的，则用户A根据用户B的通信地址即可获取该键(用户B的通信地址)对应的值Mb。
S23：用户A将键Kab添加到值Mb中，更改后的值Mb将写回到区块链上。
本实施例中，用户A在读取用户B的通信地址对应的值Mb时，执行修改指令，将键Kab添加到值Mb中，可以表示为Mb+Kab。将键Kab添加到值Mb后，Mb发生了更改，更改后的Mb将写回到区块链上。需要说明的是，区块链系统有两个概念：区块和当前数据状态(fabric中的world state，比特币中的UTXO)。区块中是历史交易信息，当前数据状态是由所有的历史交易所得到的系统数据状态。本实施例中所有的创建或修改等操作，都是通过发送一个交易，经过区块链系统本身的验证，得到一个区块。最终区块链上所有用户根据区块将交易执行，实现对当前数据状态的修改。另外，交易动作会包含在一个区块中，一个区块中可能有多个交易；读取操作不会产生区块，不算交易；区块链系统会按照一定的时间间隔产生区块，每个区块中包含这个时间间隔中所有的交易。本实施例中将键Kab添加到值Mb中是区块链上的一个交易，经过区块链系统本身的验证，在该交易所在的时间间隔结束后，该交易将被打包到该时间间隔的区块中，最后区块链上所有用户根据该区块将键Kab添加到值Mb这个交易执行，实现对当前数据状态的修改，即成功将更改后的Mb写回到区块链上。
S30：用户B基于用户B的通信地址对应的值Mb中写入的键Kab，获取值Data1。
本实施例中，由于用户B的通信地址对应的值Mb已被更改，用户B基于自身的通信地址对应的值Mb能够获取由用户A写入到值Mb中的键Kab，能够根据键Kab获取该键Kab对应的值Data1。可以理解地，值Data1即用户A发送给用户B的数据，用户B根据用户A在用户B的通信地址中添加的键Kab，通过区块链系统读取自身的通信地址对应的值Mb获取键Kab，再根据键Kab和值Data1是一个键值对的关系获取值Data1。通过键值对以及结合区块链系统的方式，实现了区块链上任意两个用户点对点进行通信的功能。该区块链上任意两个用户点对点进行通信可以理解为在区块链系统上虚拟出了一条通信通道，并实现所有用户之间的数据通信。用户只需要维护与区块链系统的网络通信，即可实现数据共享存储和所有用户间的数据通信，可以有效地简化应用系统的构建难度，降低系统复杂性，在不增加区块链系统复杂度的前提下，解决了区块链上用户进行通信的问题。
在一具体实施方式中，如图4所示，步骤S30中，用户B基于用户B的通信地址对应的值Mb中写入的键Kab，获取值Data1，具体包括如下步骤：
S31：用户B读取用户B的通信地址，获取值Mb。
本实施例中，用户B是区块链上除用户A外的任意一用户，用户B读取自身的通信地址，由于用户B的通信地址是值Mb对应的键，用户B基于区块链系统通过自身的通信地址读取到该键相对应的值Mb。
S32：用户B从值Mb中获取键Kab。
本实施例中，在步骤S23中用户A已将键Kab添加到值Mb中，值Mb在键Kab添加后发生了更改，用户B从更改后的值Mb中获取键Kab。可以理解地，若从用户B的通信地址对应的值Mb中读取到键Kab,由于键Kab是用户A给用户B发送的数据存储在区块链上的索引，说明区块链中存在用户A给用户B发送的数据。
S33：用户B根据键Kab获取键Kab对应的值Data1。
本实施例中，根据键Kab和值Data1是一个键值对的关系，直接根据键Kab获取键Kab对应的值Data1，以读取用户A发送给用户B的数据Data1，从而实现用户A与用户B之间点对点数据交互。
可以理解地，步骤S20是用户A通过区块链给用户B写入数据的过程，而步骤S30是用户B通过区块链获取用户A发送的数据的过程，基于步骤S20和S30可在区块链上实现用户A向用户B发送数据，且用户B接收用户A的数据的点对点通信过程，无需另行创建专用于信息交互的数据通信通道，无需增加区块链系统的复杂性和构建难度。
在一具体实施方式中，步骤S20之后，即在用户A在用户B的通信地址对应的值Mb中写入键Kab，键Kab对应的值为Data1之后，该区块链上用户通信方法还包括如下步骤：基于用户B的通信地址检测到对应的值Mb发生更改，用户B获取与值Mb发生更改相关的提醒信息。
本实施例中，在值Mb发生更改后，用户B将会根据自身的通信地址检测到对应的值Mb发生更改，此时，用户B将获取与值Mb发生更改相关的提醒信息。具体地，可以是通过执行预先设定的定时检测程序，每隔一时间间隔便自动检测通信地址对应的值Mb，并比较两次检测到的值Mb是否发生更改，若发生变更，则向用户B发送与值Mb发生更改相关的提醒信息。如将上一时间间隔结束时刻的值Mb和当前时刻时间间隔结束时刻的值Mb进行比较，若两个时间点的值Mb不同，则认为值Mb发生了更改。在值Mb发生变化之后，执行发送与值Mb发生更改相关的提醒信息的指令，能够使用户B及时获取数据更新的消息，及时收取数据Data1。
在一具体实施方式中，如图5所示，步骤S30之后，即在用户B基于用户B的通信地址对应的值Mb中写入的键Kab，获取值Data1之后，该区块链上用户通信方法还包括如下 步骤：
S40：用户B在用户A的通信地址对应的值Ma中写入键Kba，键Kba对应的值为与值Data1相对应的值Data2。
其中，用户A的通信地址对应的值为Ma，键Kba和值Data2是一个键值对，用于存储用户B在区块链上传给用户A的数据。值Data2与值Data1相关联。例如键Kba的数据前缀在这里可以使用时间戳，以突出进行反馈的时间。本实施例中，基于区块链系统，用户B在用户A的通信地址对应的值Ma中写入键Kba。该键Kba对应的值是Data2，即用户B想要给用户A发送的根据Data1反馈的数据为Data2。其中，写入操作为修改操作，通过修改操作将键Kba添加(写入)到值Ma中。可以理解地，本步骤与步骤S20相似，本步骤为用户B在接收到用户A发送的值Data1后，反馈发送数据(值Data2)的过程。通过在用户A的通信地址对应的值Ma写入键Kba，实现了将数据对应的键Kba写入到值Ma中的目的。
S50：用户A基于用户A的通信地址对应的值Ma中写入的键Kba获取值Data2。
本步骤与步骤S30相似，本步骤为用户B在接收到用户A发送的值Data1，后，反馈发送数据(值Data2)后，用户A基于区块链系统读取用户B根据值Data1反馈过来的数据(值Data2)的过程。本实施例中，由于用户A的通信地址对应的值Ma已被更改，用户A基于自身的通信地址对应的值Ma中的由用户B写入的键Kba，能够根据键Kba获取该键对应的值Data2。可以理解地，值Data2即用户B反馈给用户A的数据，用户A根据用户B在用户A的通信地址中添加的键Kba，通过自身的通信地址获取键Kba，再根据键Kba和值Data2是一个键值对的关系获取值Data2，完成用户B根据用户A发送的值Data1反馈给用户A的值Data2。通过键值对的方式以及结合区块链的特点，实现了区块链上任意两个用户点对点进行通信的功能。可以理解地，即在区块链系统上虚拟出一条通信通道，实现所有用户之间的数据通信。用户只需要维护与区块链网络的通信，即可实现数据共享存储和所有用户间的数据通信，可以有效地简化应用系统的构建难度，降低系统复杂性，在不增加区块链系统复杂度的前提下，解决了区块链上用户进行通信的问题。
需要说明的是，区块链具有数据共享和数据不可篡改等特点，基于区块链上的用户通信应该对区块链上用户通信的数据进行加密保存和设置有限授权访问，以保证区块链上用户通信的信息安全，在区块链上只有授权的用户才能够解密被加密的用于通信的数据，实现在区块链上的用户通信。
本实施例所提供的区块链上用户通信方法中，首先以键值对方式创建区块链上每一用 户的通信地址，创建基于区块链的用于区块链上用户进行信息交互的通信地址，结合区块链系统以及键值对的性质和特点，为后续区块链上用户信息交互的实现提供基础。然后用户A在用户B的通信地址对应的值Mb中写入键Kab，键Kab对应的值为Data1，用户A和用户B为区块链上任意选取的两个用户，通过利用键值对的特点将用户A要发送给用户B的值Data1对应的键Kab写入到用户B的通信地址对应的值Mb中，使得Mb中包含有值Data1对应的键Kab，通过以键值对方式创建的通信地址及其对应的值实现了将数据从A用户发送到B用户的功能。最后用户B基于用户B的通信地址对应的值Mb中写入的键Kab，获取值Data1，用户B通过自身的通信地址以及根据键值对的特点，读取通信地址中包含有用户A发送过来的值Data1对应的键Kab，实现了基于区块链系统本身的区块链上用户通信功能。本实施例所提供的区块链上用户通信方法即在区块链系统上虚拟出一条通信通道，实现区块链上任意两个用户之间的数据通信。用户只需要维护与区块链网络的通信，即可实现数据共享存储和所有用户间的数据通信，可以有效地简化应用系统的构建难度，降低系统复杂性，在不增加区块链系统复杂度的前提下，解决了区块链上用户进行通信的问题。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
