In August 2022, we shared our initial efforts to develop a modular, open-source Hardware Security Module (HSM) platform tailored for blockchain environments. Today, we are excited to update the community on the progress we’ve made, and why this work is more relevant than ever.
One of the most critical security challenges in blockchain networks is protecting cryptographic keys. While hardware wallets provide a robust solution for individual users, securing validator keys in Ethereum’s consensus layer requires a different approach. Hardware Security Modules (HSMs) are commonly used in secure environments to protect private keys and execute cryptographic operations without exposing sensitive material.
