Problems solved by technology

[0003] In short, a single consensus algorithm has become less and less applicable, and there are various problems in the face of growing blockchain applications, which has led to the exploration and attempt of various new consensus methods, composite consensus algorithms Gradually attracting more and more attention, these combined consensus methods are not universal for specific application scenarios on the one hand, and on the other hand, there are still bottlenecks in consensus efficiency
[0004] Therefore, a consensus verification method suitable for general blockchain application scenarios is needed to solve the problem of low efficiency of blockchain consensus verification and improve blockchain consensus performance

[0061] In another example, such as figure 2 Shown is a system structure diagram of the multi-party collaborative cross-validation mechanism of the present invention. Adopting the scheme of the present invention has the advantage of improving the efficiency of consensus verification. Moreover, this manner is only an illustration of a preferred example, but is not limited thereto. When implementing the present invention, the implementation style can be changed according to the user's demand for blockchain functions. In the process of the present invention, the core components related to the completion of the present invention include blockchain cache database, state database, random number contract, threshold control contract, node control contract, round control contract, verification times threshold contract and accident control contract , and the specific realization of these core components of the present invention is summarized as follows:

specific Embodiment 3

[0072] image 3 It shows a round of two-group multi-party cross-consensus verification process of the present invention. The present invention is not limited to the two-group consensus verification process, and the number of groups can be adjusted according to actual application scenarios. The number of rounds for selecting verification nodes is set with a lower limit and an upper limit. The lower limit In order to ensure that the blockchain transaction failure rate is lower than the minimum round of 33%, the upper limit is an optional round configured according to actual needs. The present invention selects two sets of verification processes to be the optimal choice for most blockchain application scenarios. Too many groups may lead to a predictable verification sequence. At the same time, the present invention can also extend multiple rounds of multi-group multi-party crossover for massive nodes. Consensus verification method. The specific implementation process of the cons...

Abstract

The invention discloses a block chain multi-party cooperative cross consensus verification method, which comprises the following steps: in a whole block chain network, setting a round of two groups of consensus verification processes, randomly selecting verification nodes as a first group of verification nodes, obtaining data needing to be verified by a system, verifying the data by the verification nodes, and verifying and supervising the verification nodes by the remaining nodes. After verification is completed, messages are broadcasted to the whole network, then the second group of nodes verify the data, the first group of verification nodes perform verification supervision, and at this time, multi-party message transmission cooperation is completed twice, a multi-party cooperation cross verification mechanism is realized in the process, and a block chain data index is formed after verification of the two groups of data is passed, and storing the processed block chain data index into a block chain cache database, and broadcasting a data verification passing result to the whole network. According to the one-round two-group multi-party cooperative cross consensus verification method, the nodes of the whole network are grouped, the verification overhead is reduced, and the consensus efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a multi-party cooperative cross-consensus verification method and system of block chains. Background technique [0002] With the development and application of blockchain technology, currently commonly used blockchain consensus methods, such as POW, POS, BFT, Paxos, Raft, etc., these commonly used consensus algorithms have become unsuitable due to the problems of low performance and high energy consumption. apply again. Therefore, in the process of technical practice, various new consensus methods have been proposed for the specific application scenarios of the blockchain. Most of these new consensus methods come from the combination and update of existing consensus methods and are not universal. [0003] In short, a single consensus algorithm has become less and less applicable, and there are various problems in the face of the growing blockchain applications, ...
