Privacy is Existential Peter Van Valkenburgh - Devconnect

Event: Devcon

Date: Jul 2026

Speaker: Peter Van Valkenburgh Event: Ethereum Day (Devconnect Argentina 2025) Keywords: Privacy, cypherpunk, blockchain, surveillance, MEV Privacy is Existential: though it may not be a right.   Privacy is often treated in cypherpunk circles as a right in itself. But does someone who chooses to act in public really have a right to demand others look away? This talk shifts the focus: from privacy as an individual right to privacy as a structural necessity for the survival of permissionless blockchains. Ethereum and other L1s rightly aspire to be “dumb pipes.” Yet dumb pipes, by definition, have no perspective on what flows through them—and if they did, they wouldn’t stay pipes for long. When validators can see and interpret every transaction, they face two existential risks: the temptation to exploit that visibility for MEV (maximum extractable value), and the liability of becoming complicit in what they observe. From private extraction to public prosecution, visibility itself becomes an attack surface—one that can and will be exploited not only by opportunistic actors, but by nation-states.
