June 20 (Cointime) - Co-founder of Ethereum infrastructure service Flashbots, Alex Obadia, is leaving the company and warning of challenges ahead. In a letter posted to Twitter, Obadia stated that the system is still vulnerable to centralization from cross-domain MEV and exclusive orderflow. Flashbots proposes blocks for validators running the Ethereum blockchain and was formed to battle negative consequences of MEV extraction techniques. Obadia said he is leaving for personal reasons and believes his vision and values will be better served elsewhere.
