Learnings from running Web3Signer at scale on Holesky
This document describes the infrastructure setup for running validation at scale using Web3Signer, which we put in place at Kiln to run our ~100k Holesky validators.One of the goals was to assess the feasibility of running validators from multiple geographical locations while keeping guarantees from Web3Signer. Initially, we adopted a straightforward approach, and this post covers some pitfalls that came up with it and the eventual enhancements we implemented. We extend our heartfelt gratitude to the ConsenSys team for their unwavering support, providing custom flags to Web3Signer that enabled us to tweak its threading model.
