Essentially, blockchain is a peer-to-peer network that relies on frequent communications within the consensus network. However, major blockchains are primarily designed in stable wired communication networks running in advanced devices. Hence, the performance and security level degradation caused by communication is negligible. While this is not the case for high dynamic wireless connected digital society that is mainly composed of massive wireless devices. Especially through the upcoming 5G, majority of valuable information exchange may be through wireless medium.

To apply blockchain in wireless environments, it is important to identify the communication procedures and roles in wireless blockchain system; and how much communication resource is needed to run a wireless blockchain network (WBN) securely. Moreover, it is an interesting topic that how the communication resource provision affects the blockchain performance such as scalability, throughput, latency and security level. The answers relate to the wireless blockchain network topology (e.g., tree, mesh, etc.), communication protocols (e.g., grant-based or contention-based), routing and scheduling.

This tutorial is comprised of three parts with the following clear objectives:

  1. Present the concept of wireless blockchain networks, with different network topology and communication protocols, for various commonly used blockchains. Present the relationship between the communication (in terms of spectrum and power provision), and the wireless blockchain network performance (in terms of scalability, throughput and latency, and security).
  2. Present MAC procedure the role of wireless blockchain network. Explain the delay caused by queueing, scheduling and transmission following MAC and the reason why blockchain system performance and security may face a bottleneck.
  3. Present the limitations for existing blockchain application in wireless networks, in terms of network behaviour modelling, consensus process modelling and so on, in addition to the related mathematical methods of analysis.
