Ethereum Foundation Co-Executive Director Tomasz shared his original motivation for getting involved in Ethereum development. In his early years, he was purely driven by technological exploration, wanting to create on-chain tools to solve problems he encountered. It was this curiosity that led him to delve deeply into Ethereum's technical architecture. Through studying the details of the Yellow Paper and practical development on the EVM, he gradually grew from a technology enthusiast into a core builder of the Ethereum ecosystem. In this process, small ideas driven by personal needs eventually evolved into contributions to the entire Ethereum network. It is this passion for technology and spirit of practice among developers that has continuously propelled the evolution of the Ethereum ecosystem.
