Co-founder of Ethereum, Vitalik Buterin, reflected on two major crises on social media: the first involving Sam Bankman-Fried and the second involving the OpenAI board. Vitalik's core concept is "public legitimacy." He suggests that individuals and organizations in the crypto field must deeply respect this principle, as the fundamental wrongdoing in both cases is not just taking controversial actions but also neglecting transparent and responsible dialogue with the public. Vitalik believes that large companies should be more open to avoid crises like FTX.
