In this embodiment, the first-type blockchain node implementation program 30 can be divided into: a configuration module 310, a connection module 320, a data request module 330, and a receiving module 340.
所述配置模块310，用于获取至少一个第二类型区块链节点的地址信息，并将其写入本地配置文件中。例如，区块链***1可以向所有区块链节点公开一个或多个第二类型区块链节点的地址信息，例如IP地址和端口号信息，假设存在与第一类型区块链节点在同一网段的第二类型区块链节点，则所述配置模块310直接将该第二类型区块链节点的IP地址和端口号信息写入该第一类型区块链节点的配置文件中；假设不存在与所述第一类型区块链节点在同一网段的第二类型区块链节点，则所述配置模块310可以通过端口映射，将某个第二类型区块链节点的地址映射到所述第一类型区块链节点所在网段的虚拟地址，并将该虚拟地址和对应的映射关系作为地址信息写入所述第一类型区块链节点的配置文件中。The configuration module 310 is used to obtain address information of at least one second-type blockchain node and write it into a local configuration file. For example, the blockchain system 1 can disclose the address information of one or more second-type blockchain nodes, such as IP address and port number information, to all blockchain nodes. If the second type of blockchain node is in the network segment, the configuration module 310 directly writes the IP address and port number information of the second type of blockchain node into the configuration file of the first type of blockchain node; suppose If there is no second-type blockchain node in the same network segment as the first-type blockchain node, the configuration module 310 can map the address of a certain second-type blockchain node to The virtual address of the network segment where the first-type blockchain node is located, and the virtual address and the corresponding mapping relationship are written into the configuration file of the first-type blockchain node as address information.

For example, the first-type blockchain node may establish a connection with the second-type blockchain node through a transport layer security (Transport Layer Security, TLS). In order to ensure communication security, the first-type blockchain node and the second-type blockchain node may establish a connection through multiple handshake (Handshake) and TLS mutual authentication.
在一个实施例中，所述连接模块320还可以对所述第二类型区块链节点的合法性进行验证。具体地，所述第一类型区块链节点和第二类型节点可以从对应的证书授权中心(Certificate Authority，CA)获取证明节点身份的数字证书，所述第一类型区块链节点在与所述第二类型区块链节点建立连接后，可以获取所述第二类型区块链节点证明节点身份的数字证书，并通过对应的可信CA验证数字证书合法性。假设通过合法性验证，则所述连接模块320可以将合法性验证结果发送给所述数据请求模块330；假设验证结果为所述第二类型区块链节点的身份不合法，则所述连接模块320将主动断开与所述第二类型区块链节点的通信连接，并记录相关信息。In an embodiment, the connection module 320 may also verify the legitimacy of the second-type blockchain node. Specifically, the first-type blockchain node and the second-type node can obtain a digital certificate proving the identity of the node from a corresponding certificate authority (Certificate Authority, CA), and the first-type blockchain node is in contact with the After the second-type blockchain node establishes a connection, the second-type blockchain node can obtain a digital certificate proving the identity of the node, and verify the legality of the digital certificate through a corresponding trusted CA. Assuming that the legality verification is passed, the connection module 320 may send the result of the legality verification to the data request module 330; if the verification result is that the identity of the second-type blockchain node is illegal, the connection module 320 will actively disconnect the communication connection with the second-type blockchain node and record relevant information.
所述数据请求模块330，用于向其他区块链节点发送数据获取请求。例如，所述数据请求模块330可以向与所在第一类型区块链节点建立通信连接的第二类型区块链节点发送请求获取区块链账本的第一请求信息，还可以发送获取邻居节点列表的第二请求信息。其中，所述第一请求信息可以包括所述第一类型区块链节点存储的区块链的状态信息，例如高度最高的区块的消息摘要(哈希值)。所述邻居节点列表中的邻居节点按照优先级排序，所述优先级是根据所述邻居节点的IP地址所在的网段和所述第一类型区块链节点的IP地址所在的网段确定的。例如，与所述第一类型区块链节点的IP地址在同一个网段的邻居节点的优先级较高。所述邻居节点可以是第二类型区块链节点，也可以是其他第一类型区块链节点。所述邻居节点列表中包括各个邻居节点的标识信息，所述第一类型区块链节点可以根据所述标识信息与对应的邻居节点建立通信连接。所述数据请求模块330可以按照所述邻居节点列表中邻居节点的顺序向对应的邻居节点发送获取区块链账本的请求。具体地，所述第一类型区块链节点向所述邻居节点列表中的第一个邻居节点发送获取区块链账本的请求，如果在预设时间阈值(例如30s)之后所述第一类型区块链节点没有接收到所述第一个邻居节点返回的区块链账本，则所述第一类型区块链节点向所述邻居节点列表中的第二个邻居节点发送获取区块链账本的请求，如果在预设时间阈值之后所述第一类型区块链节点没有接收到所述第二个邻居节点返回的区块链账本，则所述第一类型区块链节点 向所述邻居节点列表中的第三个邻居节点发送获取区块链账本的请求，以此类推，不再赘述。The data request module 330 is used to send data acquisition requests to other blockchain nodes. For example, the data request module 330 may send the first request information for obtaining the blockchain ledger to the second-type blockchain node that establishes a communication connection with the first-type blockchain node, and may also send and obtain the neighbor node list. The second request information. Wherein, the first request information may include state information of the blockchain stored by the first-type blockchain node, such as a message digest (hash value) of the block with the highest height. The neighbor nodes in the neighbor node list are sorted by priority, and the priority is determined according to the network segment where the IP address of the neighbor node is located and the network segment where the IP address of the first type blockchain node is located . For example, a neighbor node that is in the same network segment as the IP address of the first type of blockchain node has a higher priority. The neighbor node may be a second-type blockchain node or other first-type blockchain nodes. The neighbor node list includes identification information of each neighbor node, and the first-type blockchain node may establish a communication connection with a corresponding neighbor node according to the identification information. The data request module 330 may send a request for obtaining a blockchain ledger to the corresponding neighbor node in the order of the neighbor nodes in the neighbor node list. Specifically, the first-type blockchain node sends a request for obtaining a blockchain ledger to the first neighbor node in the neighbor node list, if the first-type blockchain node is after a preset time threshold (for example, 30s) If the blockchain node does not receive the blockchain ledger returned by the first neighbor node, the first type of blockchain node sends to the second neighbor node in the neighbor node list to obtain the blockchain ledger If the first-type blockchain node does not receive the blockchain ledger returned by the second neighboring node after the preset time threshold, the first-type blockchain node will report to the neighbor The third neighbor node in the node list sends a request to obtain the blockchain ledger, and so on, so I won’t repeat it.

此外，本申请还提供一种跨网段互连的区块链网络实现方法。参照图4所示，为本申请跨网段互连的区块链网络实现方法一实施例的流程示意图。该方法的如下步骤：In addition, this application also provides a method for implementing a blockchain network interconnected across network segments. Referring to FIG. 4, it is a schematic flowchart of an embodiment of a method for implementing a blockchain network interconnected across network segments according to this application. The steps of the method are as follows:
步骤S410，所述配置模块310将至少一个第二类型区块链节点的地址信息写入第一类型区块链节点的配置文件中。其中，若所述第二类型区块链节点和第一类型区块链节点在同一网段中，则所述地址信息为该第二类型区块链节点在本网段的IP地址和端口号信息； 若所述第二类型区块链节点和第一类型区块链节点不在同一网段中，则所述地址信息为该第二类型区块链节点映射到该第一类型区块链节点所在网段的IP地址和端口号信息。可以理解的是，同一个第二类型区块链节点在不同网段的映射地址可能相同也可能不同。在其他实施例中，以Mac地址代替端口号信息，也能实现类似的技术效果。In step S410, the configuration module 310 writes the address information of at least one second-type blockchain node into the configuration file of the first-type blockchain node. Wherein, if the second type blockchain node and the first type blockchain node are in the same network segment, the address information is the IP address and port number of the second type blockchain node in this network segment Information; if the second-type blockchain node and the first-type blockchain node are not in the same network segment, the address information is that the second-type blockchain node is mapped to the first-type blockchain node The IP address and port number information of the network segment. It is understandable that the mapping addresses of the same second type blockchain node in different network segments may be the same or different. In other embodiments, replacing the port number information with the Mac address can also achieve similar technical effects.
具体地，在本实施例中，假设一个第一类型区块链节点在第一网段，一个第二类型区块链节点在第二网段，所述第一网段和第二网段为不同网段，将该第一类型区块链节点的地址表示为a，该第二类型区块链节点的地址表示为b，其中a属于第一网段，b属于第二网段，a与b之间不能直接访问，即第一网段中的第一类型区块链节点和第二网段中的第二类型区块链节点无法直接通信，则可以为该第一类型区块链节点在所述第一网段中分配第一虚拟地址c，为该第二类型区块链节点在所述第二网段中分配第二虚拟地址d，在b和c之间以及a和d之间建立映射关系，将所述虚拟地址以及映射关系写入该第一类型区块链节点的配置文件中。当该第一类型区块链节点访问该第二类型区块链节点时，以第二虚拟地址d作为源地址，b作为目的地址进行访问，即，a要访问b，根据b和c之间的映射关系，变为a访问c，有根据a和d之间的映射关系，变为d访问b。在实际操作中，所述映射关系的建立可以通过哈希函数实现，为保证映射关系的唯一性，构造哈希函数时需同时考虑第一类型区块链节点以及第二类型区块链节点的IP地址、Mac地址和端口号信息。只考虑第一类型区块链节点以及第二类型区块链节点的Mac地址及IP地址，或只考虑第一类型区块链节点以及第二类型区块链节点的IP地址及端口号信息都可以实现类似的功能。本实施例仅以处在不同网段的一个第一类型区块链节点和一个第二类型区块链节点为例，介绍第一类型区块链节点配置信息的相关情况，其他第一类型区块链节点与该第二类型区块链节点和或其他第二类型区块链节点在配置文件的处理问题上可参照上述介绍，在此不再赘述。Specifically, in this embodiment, it is assumed that a first-type blockchain node is in the first network segment, and a second-type blockchain node is in the second network segment. The first network segment and the second network segment are In different network segments, the address of the first type of blockchain node is denoted as a, and the address of the second type of blockchain node is denoted as b, where a belongs to the first network segment, b belongs to the second network segment, and a and There is no direct access between b, that is, the first type of blockchain node in the first network segment and the second type of blockchain node in the second network segment cannot directly communicate, it can be the first type of blockchain node A first virtual address c is allocated in the first network segment, and a second virtual address d is allocated in the second network segment for the second-type blockchain node, between b and c and between a and d A mapping relationship is established between them, and the virtual address and the mapping relationship are written into the configuration file of the first-type blockchain node. When the first type of blockchain node visits the second type of blockchain node, the second virtual address d is used as the source address and b is used as the destination address for access, that is, a must access b, according to the difference between b and c The mapping relationship becomes a to c, and according to the mapping relationship between a and d, it becomes d to b. In actual operation, the establishment of the mapping relationship can be achieved through a hash function. To ensure the uniqueness of the mapping relationship, the construction of the hash function needs to consider both the first type of blockchain node and the second type of blockchain node. IP address, Mac address and port number information. Only consider the Mac address and IP address of the first type of blockchain node and the second type of blockchain node, or only consider the IP address and port number information of the first type of blockchain node and the second type of blockchain node Similar functions can be achieved. This embodiment only takes a first-type blockchain node and a second-type blockchain node in different network segments as an example to introduce the configuration information of the first-type blockchain node, and other first-type areas The block chain node and the second type block chain node and or other second type block chain nodes can refer to the above introduction on the processing of the configuration file, and will not be repeated here.
步骤S420，所述连接模块320根据所述配置文件中的所述地址信息向对应的第二类型区块链节点发送建立通信连接的请求，并在收到所述第二类型区块链节点的确认回应后，与其建立通信连接。依上述例子，所述第一类型区块链节点可以通过TLS与所述第二类型区块链节点建立连接。为了保障通信安全，所述第一类型区块链节点与所述第二类型区块链节点可以通过多次握手，通过TLS双向认证，从而建立连接。在其他实施例中，所述第一类型区块链节点在与所述第二类型区块链节点建立连接后，可以获取所述第二类型区块链节点证明节点身份的数字证书，并通过对应的可信CA验证数字证书合法性。假设通过合法性验证，则保持连接，允许数据交互，假设验证失败，则自动断开连接。可以理解的 是，所述第二类型区块链节点也可以通过对应的CA对所述第一类型区块链节点的身份进行验证，在此不再赘述。Step S420: The connection module 320 sends a request to establish a communication connection to the corresponding second-type blockchain node according to the address information in the configuration file, and upon receiving the second-type blockchain node After confirming the response, establish a communication connection with it. According to the above example, the first type blockchain node can establish a connection with the second type blockchain node through TLS. In order to ensure communication security, the first-type blockchain node and the second-type blockchain node may pass multiple handshake and pass TLS mutual authentication to establish a connection. In other embodiments, after the first-type blockchain node establishes a connection with the second-type blockchain node, it can obtain a digital certificate for the second-type blockchain node to prove the identity of the node, and pass The corresponding trusted CA verifies the legality of the digital certificate. Assuming that the legality verification is passed, the connection is maintained and data interaction is allowed. If the verification fails, the connection is automatically disconnected. It is understandable that the second type of blockchain node may also verify the identity of the first type of blockchain node through a corresponding CA, which will not be repeated here.
步骤S430，所述数据请求模块330向与其所在第一类型区块链节点建立连接的其他区块链节点发送数据获取请求。在本实施例中，第一类型区块链节点在根据其配置文件中的地址信息与对应的第二类型区块链节点建立连接之后，可以向该第二类型区块链节点发送获取邻居节点列表的请求。所述邻居节点列表中的邻居节点按照优先级排序，所述优先级是根据所述邻居节点的IP地址所在的网段和所述第一类型区块链节点的IP地址所在的网段确定的。例如，与所述第一类型区块链节点的IP地址在同一个网段的邻居节点的优先级较高。所述邻居节点可以是第二类型区块链节点，也可以是其他第一类型区块链节点。在得到邻居节点列表后，所述第一类型区块链节点可以向所述邻居节点列表中的第一个邻居节点发送获取区块链账本的请求，如果在预设时间阈值(例如30s)之后所述第一类型区块链节点没有接收到所述第一个邻居节点返回的区块链账本，则所述第一类型区块链节点向所述邻居节点列表中的第二个邻居节点发送获取区块链账本的请求，如果在预设时间阈值之后所述第一类型区块链节点没有接收到所述第二个邻居节点返回的区块链账本，则所述第一类型区块链节点向所述邻居节点列表中的第三个邻居节点发送获取区块链账本的请求，以此类推，不再赘述。当然，所述第一类型区块链节点也可以直接向根据其配置文件中的地址信息建立起连接的第二类型区块链节点发送获取区块链账本的请求，本实施例选择先获取邻居节点列表再向邻居节点发送获取区块链账本的请求仅为减少同步区块时的网络延迟，以从整体上提高区块链***性能，并非对发明内容进行限定，在此不再赘述。Step S430: The data request module 330 sends a data acquisition request to other blockchain nodes that have established connections with the first type of blockchain node where it is located. In this embodiment, after the first type of blockchain node establishes a connection with the corresponding second type of blockchain node according to the address information in its configuration file, it can send to the second type of blockchain node to obtain neighbor nodes List request. The neighbor nodes in the neighbor node list are sorted by priority, and the priority is determined according to the network segment where the IP address of the neighbor node is located and the network segment where the IP address of the first type blockchain node is located . For example, a neighbor node that is in the same network segment as the IP address of the first type of blockchain node has a higher priority. The neighbor node may be a second-type blockchain node or other first-type blockchain nodes. After obtaining the neighbor node list, the first-type blockchain node may send a request to obtain the blockchain ledger to the first neighbor node in the neighbor node list, if it is after a preset time threshold (for example, 30s) If the first type blockchain node does not receive the blockchain ledger returned by the first neighbor node, then the first type blockchain node sends to the second neighbor node in the neighbor node list A request to obtain a blockchain ledger, if the first type of blockchain node does not receive the blockchain ledger returned by the second neighbor node after the preset time threshold, the first type of blockchain The node sends a request for obtaining a blockchain ledger to the third neighbor node in the neighbor node list, and so on, and will not be repeated. Of course, the first type of blockchain node can also directly send a request to obtain a blockchain ledger to a second type of blockchain node that has established a connection based on the address information in its configuration file. This embodiment chooses to obtain neighbors first. The node list then sends a request to obtain the blockchain ledger to neighbor nodes only to reduce the network delay when synchronizing blocks, so as to improve the performance of the blockchain system as a whole, and is not a limitation on the content of the invention, and will not be repeated here.
步骤S440，所述接收模块340接收从其他区块链节点返回的数据。所述其他区块链节点可以是本地配置文件中的地址信息对应的第二类型区块链节点，可以是从该第二类型区块链节点获取的邻居节点列表对应的其他第二类型区块链节点或第一类型区块链节点。返回的数据可以是区块链账本，可以是邻居节点列表，也可以是其他数据信息。在本实施例中，假设所述数据获取请求为区块链账本获取请求，则该请求中可以包括请求发送方，即所述第一类型区块链节点中所存储区块链的状态信息，请求接收方，即所述其他区块链节点，可根据所述状态信息，确定所述第一类型区块链节点需要的区块链账本，生成区块链账本数据包，将其返回给所述第一类型区块链节点。例如，假设根据所述第一类型区块链节点发送的请求中的区块链的状态信息确定所述第一类型区块链节点存储的区块链中高度最高的区块为第68区块，而所述其他区块链节点存储的区块链中高度最高的区块为第89区块，则所述第一类型区块链节点需要的区块链账本为第69-89区块，所述接收模块340 可以接收到包含第69-89区块的区块链账本数据包。Step S440: The receiving module 340 receives data returned from other blockchain nodes. The other blockchain nodes may be second-type blockchain nodes corresponding to the address information in the local configuration file, and may be other second-type blocks corresponding to the neighbor node list obtained from the second-type blockchain node Chain node or first type blockchain node. The returned data can be a blockchain ledger, a neighbor node list, or other data information. In this embodiment, assuming that the data acquisition request is a blockchain ledger acquisition request, the request may include the request sender, that is, the state information of the blockchain stored in the first type blockchain node, The request recipient, that is, the other blockchain nodes, can determine the blockchain ledger required by the first type of blockchain node based on the status information, generate a blockchain ledger data packet, and return it to the all Describe the first type of blockchain node. For example, suppose it is determined that the block with the highest height in the blockchain stored by the first type blockchain node is the 68th block according to the state information of the blockchain in the request sent by the first type blockchain node , And the block with the highest height among the blockchains stored by the other blockchain nodes is the 89th block, then the blockchain ledger required by the first type of blockchain node is the 69-89th block, The receiving module 340 can receive a blockchain ledger data packet containing blocks 69-89.
本实施例提出的跨网段互连的区块链网络实现方法，通过将第二类型区块链节点的地址信息写入各个第一类型区块链节点的配置文件中，各个所述第一类型区块链节点可以根据其配置文件中的所述地址信息与对应的所述第二类型区块链节点建立连接并完成信息交互，从而克服位于不同网段的区块链节点无法直接通信的技术问题，实现跨网段互联的区块链网络。相对创世区块中的信息，各个所述第一类型区块链节点的本地配置文件中的配置信息更易于进行灵活增删和修改，因此利用该区块链网络实现方法，还便于对区块链***进行扩展和变更。例如，在其他实施例中，该方法还可以包括：In the implementation method of a blockchain network interconnected across network segments proposed in this embodiment, the address information of the second-type blockchain node is written into the configuration file of each first-type blockchain node. The type of blockchain node can establish a connection with the corresponding second type of blockchain node according to the address information in its configuration file and complete information interaction, thereby overcoming the inability of blockchain nodes located in different network segments to communicate directly Technical issues to realize a blockchain network interconnected across network segments. Compared with the information in the genesis block, the configuration information in the local configuration file of each of the first-type blockchain nodes is easier to add, delete, and modify flexibly. Therefore, using this blockchain network implementation method is also convenient for block The chain system is expanded and changed. For example, in other embodiments, the method may further include:
