EF's new board seat goes to a SEAL: Caversaccio joins Buterin's "security council" 🛡️

The Ethereum Foundation has added Pascal Caversaccio, a co-founder and lead of the crypto security response group SEAL 911, to its four-member board on an initial one-year voluntary term. The Foundation announced the appointment on Wednesday, framing the body as a "security council" tasked with protecting its mission and ensuring compliance as a Swiss foundation.

Caversaccio, known online as "pcaversaccio," joins President Aya Miyaguchi, Ethereum co-founder Vitalik Buterin and Swiss counsel Patrick Storchenegger. The board sets the Foundation's vision and oversees whether management's strategies and decisions remain aligned with its values. The new member is a longtime Ethereum contributor and part of the Foundation's Silviculture Society, an informal advisory group focused on censorship resistance, open-source development, privacy and security. He authored The Ethereum Cypherpunk Manifesto in 2024 and Ethereum Privacy: The Road to Self-Sovereignty in 2025.

The appointment follows the Foundation's June statement describing privacy and security as "non-negotiable protocol guarantees," with its protocol team tasked with turning research, including layer-1 privacy and post-quantum security, into changes that preserve Ethereum's self-sovereignty. Ethereum and Solana led crypto hack losses in the first half of 2026, according to blockchain security firm Blockaid, underscoring the stakes as the Foundation reorganizes around those priorities.
