Implementation method of blockchain consensus protocol based on wireless air computing

Abstract

A method for implementing a block chain consensus protocol based on wireless air computing includes a base station and N wireless terminal nodes in a wireless block chain network, and the base station communicates with the terminal nodes through a wireless channel. The method includes: Step 1. At the beginning of each round of consensus, the base station broadcasts the update request information to all terminal nodes; Step 2. Each terminal node packs a block, calculates and generates a block hash value and sends it to the base station ; Step 3. The base station receives the linear superimposed signals of all terminal nodes, processes them through calculation and forwarding technology and broadcasts them to all participating consensus nodes; Step 4. The terminal nodes use a two-stage hash verification method to determine whether consensus is reached; The terminal node sends confirmation information to the base station to complete the current round of consensus. The invention reduces the influence of noise transmitted in the wireless channel through coding and wireless air computing technology, and realizes an efficient and reliable block chain consensus protocol.

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
