Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0037] The present invention provides a consensus method suitable for wireless blockchain networks, such as figure 1 As shown, this method can make the entire block chain network through workload proof calculation, physical carrier sense and setting transmission rules between nodes when the transmission information between miner nodes in the wireless blockchain network is uncertain and the channel is unstable. All nodes in the block chain network reach a consensus within the optimal number of rounds. This technology solves the node consensus problem in the wireless blockchain network, and avoids the fork problem in the blockchain network to a certain extent.

[0038] like figure 2 As shown, the specific examples are as follows:

Abstract

The invention discloses a consensus method suitable for a wireless block chain network. The consensus method comprises the following steps: (1) a leader election stage: electing a unique leader minernode in the wireless block chain network; (2) a block proposal stage: generating and broadcasting a new block by the leader miner node generated in the election stage; (3) a block verification stage:verifying the new block by other miner nodes and feeding back a verification result to the leader miner node; and (4) a block chain updating stage: the leader miner node deciding whether to update thelocal block chain according to the verification information of other nodes to achieve a consensus. According to the method, under the conditions that transmission information between miner nodes is uncertain and a transmission channel is unstable, through methods such as proof of work calculation, physical carrier sensing and setting of inter-node transmission rules, all nodes in the whole blockchain network reach consensus in the optimal operation round number, and the bifurcation problem in the block chain network is avoided to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of distributed networks, and in particular relates to a consensus method suitable for wireless blockchain networks. Background technique [0002] Since the birth of Bitcoin in late 2008, cryptocurrencies and related blockchain technologies have attracted increasing interest from academia and industry. As the underlying technology behind Bitcoin, blockchain is essentially a distributed database system that keeps track of all transactions that occur in the network and is replicated at every participating full node in the blockchain network. The core technology of the blockchain is a distributed consensus protocol. [0003] Although blockchain has been widely used in finance, logistics and other fields, its application in the field of mobile services is still very limited. This is because there are two relatively big challenges to be dealt with in the wireless network environment. One is to solve the problem ...
