Danny Ryan, a researcher at the Ethereum Foundation, announced his departure to end his seven-year contribution to the Ethereum ecosystem. He said on GitHub that the reasons for leaving were personal and to make room for new opportunities, stressing that the decision did not reflect problems with Ethereum or the crypto industry. Ryan has been instrumental in key upgrades to Ethereum, including the launch of the Beacon Chain in 2021 and the implementation of the "Merge" protocol, and he has also been actively involved in progress updates on Ethereum improvement proposals. He said that while the experience of working on Ethereum has been invaluable, he is now ready to take a step back and find a new direction.
