Aya Miyaguchi, the Executive Director of the Ethereum Foundation, is stepping down from her role to become the foundation's president.The decision was made around one year ago, but recent criticism of the foundation and Miyaguchi contributed to the timing of the announcement.The Ethereum community has accused the foundation of being too passive in growing the ecosystem and focusing too much on layer 2 networks.The leadership change follows tough competition from other layer 1 networks, such as Solana.
