As shown in fig. 1, the method includes:
In this embodiment, the initiating node establishes the group according to the blockchain identifier of the participating node, where the blockchain identifier of the participating node may be obtained from the domain name blockchain, or may be obtained by instructing a user to input through a human-computer interface.
When registering a group, an originating node sends a first broadcast message on a domain name block chain, which is digitally signed using a private key of the originating node before sending. The broadcast message includes information (e.g., a blockchain identifier, a public key, an IP address, etc.) of at least one forwarding node for forwarding the message within the group, blockchain identifiers of all participating nodes in the group, identifiers of group communications (for distinguishing groups), and may even include a client file, so that the participating nodes can download and install clients for group communications through the client file. When the broadcast message includes the client file, the information of the at least one forwarding node may be included in the client file.
Further, the accounting node on the domain name block chain verifies the private key signature of the first broadcast message after receiving the first broadcast message, and if the verification is passed, the group is registered on the domain name block chain, and the registration information includes information carried in the first broadcast message.
In this embodiment, the first participating node may be any participating node in the group, and the first participating node may periodically query the group to which the first participating node belongs and the state of the group to which the first participating node belongs on the domain name block chain (for example, whether the group is still maintained, whether the group is disassembled, or whether other participating nodes in the group are online, etc.). Or in other embodiments, the first participating node may also search a group where the first participating node is located from the domain name blockchain under the trigger of the user, for example, a corresponding trigger key (including a virtual key or an entity key) may be set on a user interaction interface of the first participating node, and the user may trigger the first participating node to query the group where the first participating node belongs and/or a state of the group where the first participating node belongs from the domain name blockchain by using the trigger key, where when the group where the first participating node is located is searched, the first participating node searches the group where the first participating node belongs by using a domain name blockchain identifier of the first participating node, and when the group registered on the domain name blockchain includes the blockchain identifier of the first participating node, the first participating node belongs to the group.
Further, after finding the group where the first participating node is located, the first participating node obtains information of at least one forwarding node of the group from the registration information of the group on the domain name block chain.
Optionally, when the registration information of the group includes the client file of the group, after the first participating node queries the group to which the first participating node belongs, the first participating node may obtain the information of the at least one forwarding node by downloading the client.
Optionally, after the first participating node downloads and runs the client, the user may also be asked whether to join the group through the user interface, and the message is received or sent through the client only after the user confirms to join the group.
In this embodiment, the forwarding list of each forwarding node may be configured and issued by the originating node for each forwarding node, and the forwarding list of each forwarding node stores information (e.g., a block chain identifier, an IP address, etc.) of a participating node that each forwarding node is responsible for forwarding. Meanwhile, the initiating node can update the forwarding list of each forwarding node in real time according to the change condition of the members in the group so as to avoid unnecessary forwarding.
When sending the message, the first participating node forwards the message to each forwarding node according to the information of each forwarding node recorded on the domain name block chain, and each forwarding node forwards the message to the corresponding participating node according to the forwarding list of the forwarding node after receiving the message, thereby realizing group communication.
In this embodiment, the initiating node registers the group to the domain name block chain, and records the information of at least one forwarding node in the registration information of the group on the domain name block chain, so that the first participating node in the group can search the domain name block chain to obtain the information of at least one forwarding node in the group, and when sending the message, sends the message to the forwarding nodes, so that the forwarding nodes forward the message to the participating nodes in the group recorded in their respective forwarding lists according to their respective stored forwarding nodes. Therefore, group communication based on the domain name block chain is realized, especially forwarding nodes registered by the initiating node are all considered reliable nodes by the initiating node, and when the message is forwarded, the message can be guaranteed to be forwarded to participating nodes in the group, so that the reliability of the group communication is improved.
