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 random number consensus recommendation method BCMR (a blockchain consensus method by random number, or blockchain choose method by random number) is given, which 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 random number x:

[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, there are Z nodes P that 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 2 、x 3 ,...,x i ,...,x z ; that is, P i holding x i .

[0028] Step 2. Node P pushes data blocks to o...

Abstract

The invention provides a blockchain random number consensus choosing method for a ledger. The method comprises the following steps: all specific nodes in a consortium respectively produce random numbers xi, the random numbers xi are mutually synchronized among all specific nodes; each specific node computes a function f1 for all random numbers xi to acquire reference values M of all random numbers; in each specific node, a candidate ledger function value J is computed by the reference value M and the random number xi through a function f2; the node Pi having f2(xi, M) satisfying the preset feature and holding the random number xi is taken as a candidate ledger; and the candidate ledgers are mutually synchronized among all specific nodes, and the ledger is chosen.

Description

technical field [0001] The invention relates to a block chain technology, which is a block chain random number consensus recommendation method. 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. [0003] Among the three types of b...
