Problems solved by technology

However, Bitcoin requires a lot of time-consuming calculations to determine the bookkeeper, which is an inefficient method for determining the bookkeeper, and does not meet the requirements of the alliance chain
However, the current method of recommending bookkeepers in the alliance chain is not random, so it has the characteristics of centralization

Embodiment 1

[0023] Embodiment 1, figure 1 A blockchain multidimensional random number consensus recommendation method BCMMR (a blockchain consensus method by multidimensional random number, or blockchain choose method by multidimensional random number) is given. This method is suitable for the recommendation of bookkeepers in alliance chains.

[0024] The specific steps are as follows:

[0025] Step 1. Any node P in the alliance generates a set of vector random numbers X i (x i，1 , x i，2 ,...x i，j ,...x i，m ):

[0026] In the time △(△=|t k -t k+1 |,t k is the start time of a certain referral, t k+1 is the start time of the next recommendation), among the N nodes P in the alliance, Z nodes P are actually online, and the Z nodes P generate corresponding random numbers X respectively;

[0027] That is, at time t i (time t i at t k to t k+1 between), the actual online node is P 1 ,P 2 ,P 3 ,...,P i ,...,P z ; Then, the corresponding random number generated is X 1 (x 1，1 ,...

Abstract

The invention provides a multi-dimensional random number consensus election method of a block chain. The method comprises: all specific nodes in an alliance generate one group of vector random numbers Xi (xi, 1, xi, 2, ..., xi, j, ..., xi, and m) randomly and respectively; the random numbers Xi (xi, 1, xi, 2, ..., xi, j, ..., xi, and m) are synchronized mutually among all specific nodes; for each specific node, component average value calculation is carried out, comprehensive average value calculation is carried out, and then random number average value calculation is carried out; for each specific node, distances between the random number average values and the comprehensive average values are compared and a node Pi that has the minimum or maximum distance and has an average random number value is selected as a candidate account keeper; and the candidate account keepers are synchronized mutually among all specific nodes and the same account keeper elected by all nodes is used as an account keeper.

Description

technical field [0001] The invention relates to a block chain technology, which is a method for determining candidates by using a multi-dimensional random number consensus. Background technique [0002] Blockchain technology is currently a popular technology, which can be divided into three categories: public chain, alliance chain and private chain. The public chain has no central server. The nodes participating in the public chain can freely access the network according to the rules of the system. The nodes work based on the consensus mechanism. Bitcoin is a typical public chain. The consortium chain is composed of nodes with preset participating members, and node network access and exit are carried out within the consortium. Private chains are generally established within an enterprise, and the operating rules of the system are set according to the requirements of the enterprise. Members entering the private chain are still controlled and formulated by the center. [000...
