The Ethereum Foundation has adopted a dual executive director model to enhance decision-making and execution efficiency, according to Tomasz Stanczak, one of the co-executive directors. In an interview, Stanczak explained that he focuses on external communication and public representation, while the other executive director handles internal communication, operational coordination, and matters related to Treasury and DeFi. The directors maintain communication on key issues but operate independently in daily tasks, with flexibility to adjust roles based on phase and regional needs.
