Detailed Description
In order to make those skilled in the art better understand the technical solutions of the present invention, 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a block chain based group to-do function implementation method according to an embodiment of the present invention, where the embodiment is applicable to a case where a first node generates and sends a group to-do transaction request, and a designated second node receives and completes the group to-do transaction request, the method may be executed by a block chain based group to-do function implementation device, and the block chain based group to-do function implementation device may be implemented in a hardware and/or software manner, and may generally be configured in a block chain system having a data processing function. As shown in fig. 1, the method includes:
s110, the first node generates a group transaction request to be handled.
Since the group to-do function is realized by adopting a block chain-based decentralized mode, the invention can be executed by nodes in a block chain system consisting of all group members in an instant messaging group, and for the convenience of understanding the nodes executing different functions in the invention, all node names in the following embodiments of the invention are explained herein.
The first node is a user node initiating a group to-do transaction request; the second node is all user nodes except the first node in the instant communication group; the target second node is a target user node in the second node to which the group pending transaction request is directed, namely the user node which needs to respond and complete the group pending transaction request.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The reason for realizing the group to-do function based on the block chain is that the processing of the group to-do data can be transferred from the central server to each user node in the communication group based on the block chain in consideration of the computer technology used by the block chain, so that the influence on the group to-do function during the instant communication traffic peak can be effectively avoided.
The group to-do transaction request may include node identifiers corresponding to a plurality of first target group members that need to complete backlog.
It is understood that the node identifier is identification information for distinguishing each node, and may be a unique communication certificate code matched with each group member in the instant communication group.
Optionally, the group pending transaction request may further include at least one group pending item to be completed, and a first encrypted ledger book sequence number obtained by encrypting the first node local ledger book sequence number.
In one embodiment, the group backlog may be filling an online form, uploading a document, receiving a group file, and the like, and the specific group backlog request content may be generated according to the actual needs of the user, which is only illustrated here.
The accounting book sequence number is a sequence number used for identifying a group to-do block chain accounting book locally maintained by each node, and the group to-do block chain accounting book locally maintained by each node has a unique accounting book sequence number. When each group member of the instant messaging group joins the group, the account book sequence number matched with each group to-be-handled block chain account book is generated while the group to-be-handled block chain account book locally maintained by each node is generated, and the account book sequence numbers of all nodes in the communication group are stored in the group to-be-handled block chain account book locally maintained by each node in the communication group.
An optional generation mode of the accounting book sequence number may be that, according to the related data information of the instant messaging group, a secure hash algorithm is adopted to calculate and obtain the accounting book sequence number matched with each node.
And S120, the first node broadcasts the group to-do transaction request to the block chain system, and updates a locally maintained group to-do block chain account book according to the group to-do transaction request.
It can be understood that the group pending transaction request may be broadcast in a manner that the group pending transaction request is forwarded to each second node in the instant messaging group through the server. At this time, the server only needs to forward the group transaction request to be handled, and data of the group transaction request to be handled does not need to be processed.
S130, when each second node receives the group to-do transaction request, if the group to-do transaction request is determined to point to a local node, after the group to-do transaction request is determined to be a legal request, the locally maintained group to-do block chain account book is updated, and after the group to-do transaction request is executed, a transaction completion request is generated and broadcast to the block chain system.
In a specific implementation manner, the node identifier in the group pending transaction request may be obtained by analyzing the group pending transaction request, and it may be determined whether the node identifier in the group pending transaction request is the same as the local node identifier, that is, whether the group pending transaction request is directed to the local node. And if the node identifier in the group pending transaction request is the same as the local identifier, indicating that the group pending transaction request points to the local node.
In an embodiment of the present invention, a second node of the group pending transaction request directed to the local node may be used as a target second node.
Further, the target second node may verify whether the group pending transaction request is a legal request by verifying whether an account book sequence number in the group pending transaction request exists in a locally maintained group pending block chain account book.
Specifically, the first node may encrypt the local account book sequence number, add the encrypted local account book sequence number to the group pending transaction request, and broadcast the group pending transaction request to the blockchain system. The target second node can analyze the sequence number of the encrypted account book in the group to-be-handled transaction request through a secret key pre-stored in the group to-be-handled block chain account book maintained locally, and verify whether the group to-be-handled transaction request is a legal request or not by using the analyzed sequence number of the account book.
After determining the group pending transaction request, the target second node may update the locally maintained group pending block chain ledger book according to the group pending transaction request.
After the target second node completes the group to-do transaction request, a transaction completion request may be generated and broadcast to the blockchain system for the first node and other target second nodes to receive the transaction completion request.
According to the technical scheme of the embodiment of the invention, the group to-do transaction request is generated by the first node and is broadcast to the block chain system, the group to-do transaction request is verified and processed by each second node, and the transaction completion request is generated after the group to-do transaction request is completed and is broadcast to the block chain system, so that the group to-do function in the instant messaging group can be realized based on the block chain, the related operation for realizing the group to-do function is distributed to the user nodes, and the condition that the group to-do function is influenced when the instant messaging flow is in a peak is avoided.

Optionally, when each group member joins the instant messaging group, after each node generates a group to-do blockchain ledger book, the same secret key for decrypting the encrypted ledger book sequence number may be stored in the local group to-do blockchain ledger book of each node.
And S2100, after determining that the group to-do transaction request is a legal request, the target second node updates the locally maintained group to-do block chain account book according to the to-do matters in the group to-do transaction request and the first encrypted account book sequence number.
