Current Position & Biography
Antonio Sanso is a researcher at the Ethereum Foundation. His personal website identifies that role, and the Foundation’s cryptography-team page describes his focus on isogenies, elliptic curves, public-key cryptography and cryptanalysis. His public professional profile lists Basel, Switzerland as his location. This profile concentrates on his research role rather than treating older descriptions of his work at Adobe as a current appointment.
Notable Contributions
Sanso’s EthCC 2026 presentation addressed post-quantum transaction signatures for Ethereum. Its published description examines the engineering requirements of that transition and discusses account abstraction as a route for experimentation and potential future protocol support. Those are research and implementation directions, not a claim that Ethereum has already completed a post-quantum migration. The topic links mathematical cryptography to the concrete problem of how users authorize transactions.
Why Katharos.ai Is Following Them
Katharos.ai follows Sanso because changes to cryptographic foundations can affect a blockchain long before users notice a difference in its interface. A signature scheme must be evaluated not only for mathematical security but also for costs, compatibility and the practicalities of migration. His work provides a useful point of reference for distinguishing careful preparation from unsupported claims that a system is already protected against every future threat.
Areas to Follow
Post-quantum signatures, elliptic-curve research, cryptanalysis and Ethereum’s cryptographic engineering. Coverage will distinguish proposals, prototypes, protocol decisions and deployed features. Particular attention will go to the gap between demonstrating a technique and integrating it into systems with existing accounts, applications and operational constraints.
Reporting Scope
Switzerland reflects the location Sanso lists on his public professional profile, not an inference about nationality or the location of every Ethereum Foundation activity. Reporting concerns public technical work and conference contributions. It does not imply endorsement by the Foundation, a guarantee that software is secure, or investment advice about a digital asset.
