Vitalik Buterin, co-founder of Ethereum, has addressed concerns regarding centralization within the Ethereum Foundation, highlighting ongoing governance reforms aimed at enhancing transparency and decentralization. Buterin confirmed leadership changes at the Foundation, which have been underway for nearly a year, and clarified that a recent $13 million ETH sale was not connected to the Foundation. The Ethereum Foundation now holds less than 0.3% of the total ETH supply, significantly reducing perceived risks of centralized control. Buterin also cautioned about vulnerabilities associated with corporate ETH holdings and emphasized the importance of robust governance frameworks to ensure Ethereum's sustainability as a decentralized protocol.
