EIP-7702: Ethereum’s Next Step Toward a More Flexible Account Model

ByMarco López

Externally Owned Accounts (EOAs) and smart contracts in Ethereum have traditionally been distinct: EOAs are controlled by private keys and can initiate transactions, while smart contracts can execute code when triggered but cannot initiate transactions.

EIP-7702 bridges this gap by allowing EOAs to execute code, effectively blurring the lines between them and smart contracts. This proposal represents a major step toward native account abstraction, enhancing Ethereum’s usability, security, and programmability.

BLS-HSM for Ethereum: Enhancing Validator Key Security

ByMarco López

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
