Tomasz Stańczak, Executive Director of the Ethereum Foundation, has resigned amid ongoing internal power struggles, according to a post by Ethereum consensus layer core contributor Greg. Stańczak's departure highlights the challenges within the Foundation, which has faced difficulties in implementing reforms due to organizational inertia and the absence of key figure Vitalik Buterin over the past year. Stańczak, who has a background with Nethermind, Flashbots, and venture capital, initially sought to drive internal reforms but faced resistance. Despite disclosing potential conflicts of interest, his efforts were not widely accepted, leading to questions about his conduct from some community members. Stańczak's resignation underscores the need for the Ethereum Foundation to bring in leadership with strong business acumen to address inefficiencies and stalled projects.
