Hardware

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.

However, there has been a notable absence of open-source HSMs supporting BLS signatures, the cryptographic scheme essential for Ethereum validators. Recognizing this gap, Decentralized Security initiated the development of an open-source BLS-HSM
