In my EPF project, I implemented Ethshadow, a configuration generator for simulating Ethereum networks using Shadow, and used it to research improvements to the current state of PeerDAS and to estimate the effects of IDONTWANT on node bandwidth. In this presentation, I will present my findings and make a case for testing using Ethshadow.

Shadow Network Simulations

Previously, when Ethereum client developers wanted to test their ideas on the network layer, they either had to use a simulation tool that could be used only with some programming language or had to do network emulation instead, which requires a cluster of computers to do it at scale rather than running it on a laptop-size machine. This talk will tell you how to simulate an Ethereum network with 100+ nodes on a laptop-sized machine with production Ethereum clients.
