Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
Fig. 1 is a flowchart of a group communication method based on a domain name block chain according to an embodiment of the present invention, where the method is applied to a domain name block chain, and the domain name block chain includes an initiating node and a participating node of a group, where the initiating node establishes the group and registers the group to the domain name block chain, the participating node is a member of the group, and the participating node of the group includes the initiating node. As shown in fig. 1, the method includes:
In this embodiment, the initiating node may obtain the blockchain identifier of the node participating in the own group from the domain name blockchain, or may instruct the user to input the blockchain identifier of the node participating in the group through the human-computer interaction interface.
The information of the client in this embodiment at least includes a download address or a client file of the client and a hash value corresponding to the client. In this embodiment, the obtaining manner of the client information may be set, for example, the initiating node may extract and obtain preset client information from its own data storage unit, or may instruct the user to input the information of the client through a user interface.
Optionally, the first broadcast message in this embodiment may further include an identifier of a group established by the originating node, so as to distinguish the group from other groups registered on the domain name blockchain.
Further, after the originating node generates the first broadcast message, in order to ensure the security of message propagation, the originating node uses its own private key to sign the first broadcast message, and sends the signed broadcast message to the domain name block chain. And after receiving the first broadcast message, the accounting node on the domain name blockchain verifies the private key signature of the first broadcast message, if the verification is passed, the group is registered on the domain name blockchain, and at least the blockchain identifications of all the participating nodes in the group are recorded in the registration information, so that the information of the client end used for communication in the group can be even included in the group identification.
In this embodiment, the first participating node may be any participating node of 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 (for example, whether the group is still maintained, whether the group is broken away, or whether other participating nodes in the group are online, etc.), or in other embodiments, the first participating node may also search its own group 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 the user interaction interface of the first participating node, and the user may trigger the first participating node to query its own group or its own group status from the domain name blockchain through the trigger key, which is, of course, only for illustration and is not a sole limitation to the present invention.
And 103, the first participating node acquires the information of the clients of the group from the domain name block chain, and downloads and installs the clients according to the information of the clients.
For example, assuming that the information of the client included in the first broadcast message includes a download address of the client, the first participating node may automatically download the client according to the download address, or may download the client according to an instruction of the user after querying the user.
It should be noted that, although in this embodiment, the first participating node is assumed to directly acquire the information of the group client and download the client after querying that the blockchain identifier of the first participating node is included in the blockchain identifiers of the participating nodes of the group, a more humanized setting may also be added in the actual application, for example, in other embodiments, the first participating node may also query whether the user joins the group after querying that the group where the first participating node is located, and if the user indicates to join the group, the client of the group may be further downloaded and installed. Of course, this is only one embodiment and not all embodiments of the invention.
And step 104, when the first participating node sends a second broadcast message in the group, the first participating node sends the second broadcast message to the client, so that the client acquires the IP addresses of other participating nodes in the group, and sends the second broadcast message to the other participating nodes in the group according to the acquired IP addresses.
In this embodiment, a possible implementation manner is that the IP address data of the group participating node is stored in the client of the group, and when the first participating node sends the second broadcast message, the client sends the second broadcast message to other participating nodes of the group according to the IP address stored in the client. In this embodiment, a preferable design may be that the client periodically acquires and updates the IP address corresponding to each participating node in the group from the domain name block chain, so as to ensure the validity of the IP address stored in the client. Another preferable design may be that the client periodically acquires and updates the IP addresses of the online participating nodes in the group from the domain name blockchain, so that the broadcast message of the first participating node is only sent to the online participating nodes, thereby avoiding resource waste.
Another possible implementation manner is that when the first participating node sends the second broadcast message, the first participating node temporarily acquires the IP address of the group participating node from the domain name block chain through the client. And sending the second broadcast message to other participating nodes in the group according to the acquired IP address.
In this embodiment, the initiating node sends a first broadcast message for registering the group on the domain name blockchain, where the first broadcast message includes blockchain identifiers of all participating nodes in the group and information of clients for communicating in the group, so that the group is registered on the domain name blockchain; when a first participating node in the group inquires on a domain name blockchain that a blockchain identifier of the first participating node is contained in blockchain identifiers of participating nodes in the group, information of a client of the group is obtained from the domain name blockchain, and the client for communication in the group is downloaded and installed according to the information of the client, so that when the first participating node sends a second broadcast message in the group, the client can obtain IP addresses of other participating nodes in the group by sending the second broadcast message to the client, and the second broadcast message is sent to other participating nodes in the group according to the obtained IP addresses. The embodiment realizes the group communication based on the domain name block chain, and particularly, each participating node can directly send the message of the participating node to other participating nodes in the group without using a centralized node to forward the message, so that the problem of high forwarding pressure of the centralized node is avoided when the group size is large, the problem that the group cannot communicate due to the failure of the centralized node is avoided, and the reliability of the group communication is improved.

For example, the initiating node may receive notification messages for each participating node to join the group within a long period, and record information of online participating nodes in the group on the domain name block chain according to all the received notification messages when the period time arrives. Or the initiating node does not receive a notification message sent by a participating node, the online message of the participating node is recorded on the domain name block chain, and the instantaneity of the message on the domain name block chain is improved.
In this embodiment, the initiating node may also maintain the IP address of the online participating node, for example, the initiating node may periodically detect the IP addresses of the participating nodes in the group, and when it is found that the IP addresses of the participating nodes change, update the IP address of the participating node recorded in the domain name block chain in real time. So as to ensure the validity of the IP address of each participating node recorded on the domain name block chain.
