Embodiment Construction

[0082] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0083] See figure 1 , figure 1 It is a schematic diagram of a blockchain network structure provided by the embodiment of this application. Such as figure 1 The block chain network structure shown can be applied to a block chain system, and the block chain system can be a distributed system formed by connecting multiple nodes through network communication. The node here may be a server connected to the blockchain network, or a user terminal connected to the blockchain network, and...

Abstract

The embodiment of the invention discloses a data processing method and device, equipment and a storage medium; the data processing method comprises the steps that a first node generates a first preparation message based on a transaction request message, so as to enable (N1) backup nodes to carry out the signature verification of first signature information in the first preparation message, and obtain a second preparation message when the signature verification succeeds, wherein the total number N of the nodes is a positive integer equal to (3f + 1), and the f is the maximum number of illegal nodes; when a second preparation message returned by the 2f backup nodes is received, performing aggregation signature on second signature information in all received second preparation messages to obtain an aggregation message, so that (N-1) backup nodes generate a submission message when successfully verifying the aggregation message; and when the counted number of submitted messages reaches (2f+ 1), executing a request operation corresponding to the transaction request message, and returning a response message to the client. By adopting the embodiment of the invention, the network complexity during consensus can be reduced.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a data processing method, device, equipment and storage medium. Background technique [0002] When the master node in the blockchain network agrees on a broadcast message (for example, a transaction request message or a block to be verified including a transaction request message) based on a consensus algorithm (for example, the Practical Byzantine Fault Tolerance consensus algorithm, referred to as the PBFT algorithm), the block The backup node in the chain network will broadcast the preparation message generated in the preparation phase and the submission message generated in the submission phase to all nodes indiscriminately. It can be seen that the network complexity when using the PBFT algorithm for consensus is high. It should be understood that when the PBFT algorithm is used for consensus, there will be more network interaction during the consensus proces...
