Ethereum Foundation researcher Danny Ryan announced on the X platform that he has joined Etherealize as a co-creator to help Ethereum develop, and Vitalik Buterin welcomed it. Last September, Danny Ryan, a researcher at the Ethereum Foundation, announced his departure, bringing to an end his seven-year contribution to the Ethereum ecosystem. Ryan stated on GitHub that the departure was for personal reasons and wanted to make room for new opportunities, stressing that the decision did not reflect problems with Ethereum or the crypto industry. Ryan played a major role in key upgrades to Ethereum, having served as the lead coordinator for the Ethereum The Merge upgrade and overseeing the 2021 launch of the beacon chain. Ryan was also actively involved in updates on the progress of the Ethereum improvement proposal.
