A reputable crypto industry news outlet, The Block, directly reports that Tomasz Stańczak is stepping down as co-executive director of the Ethereum Foundation, naming Bastian Aue as his interim replacement. This source has high authority and relevance, suggesting it is based on verified information likely obtained from the Ethereum Foundation itself. Supporting industry coverage provides context to the leadership restructuring, though not as authoritative. No credible sources contradict the report, and mentions from social media or less formal channels neither dispute nor verify the event. Taken together, the evidence strongly supports the statement’s accuracy, with consistent information across authoritative and relevant reporting.
