Method for realizing blockchain consensus protocol based on wireless over-the-air computing

Abstract

The invention relates to a method for realizing a blockchain consensus protocol based on wireless over-the-air computing, which comprises a base station and N wireless terminal nodes in a wireless blockchain network, and the base station and the terminal nodes are communicated through a wireless channel. The method comprises the following steps that: step 1, at the beginning of each round of consensus, the base station broadcasts update request information to all terminal nodes; step 2, each terminal node packs out a block, calculates and generates a block hash value and sends the block hash value to the base station; step 3, the base station receives the linear superposition signals of all the terminal nodes, processes the signals through a calculation forwarding technology and broadcaststhe signals to all nodes participating in consensus; step 4, the terminal node determines whether a consensus is reached or not by adopting a two-stage hash verification method; and step 5, each terminal node sends confirmation information to the base station to complete the current round of consensus. Through encoding and wireless air computing technologies, the influence of noise transmitted ina wireless channel is reduced, and an efficient and reliable block chain consensus protocol is realized.

Problems solved by technology

However, in this process, the encoding, decoding and transmission of the hash value will involve high calculation and transmission overhead

Especially in wireless networks, the hash values ​​generated by different nodes need to be transmitted to the base station through orthogonal wireless channels, and then broadcast to all nodes. The wireless resource usage in these two stages increases linearly with the number of participating nodes. In a large-scale network scenario, it will cause high transmission delay and affect the efficiency of the consensus protocol
