Blockchain Consensus

In the ever-evolving landscape of blockchain technologies the ability to establish and run experiments on different typologies of local networks is a challenge. The project addresses this by introducing a system that allows user to quickly setup and visualize local Proof of Work (PoW) Ethereum (ETH) networks on Raspberry Pis (RPIs). The report introduces the reader to the concept and use case of RPIs, the characteristics of Ethereum blockchains, and the general topic of blockchain technology. It describes the requirements and discusses the design and implementation of the server-client system. The system was evaluated on several runs for grid, star and circle topologies with 3 up to 9 RPIs showcasing the consensus degradation at varying levels of delays.
