The Ethereum documentary (Vitalik: The Story of Ethereum) held its offline premiere in Hong Kong on October 10. Xiao Feng, Chairman and CEO of HashKey Group, attended the premiere with community members, and before the screening reviewed the story of Vitalik’s participation in the co-construction of the Chinese Ethereum community ecosystem in Shanghai from 2015 to 2017. Xiao Feng said: “The goal of Ethereum is to allow everyone to freely participate, contribute and share the value of blockchain technology while protecting privacy and security. Over the years, this young man who loves to wear T-shirts and program has not changed his original intention, and the Ethereum network he has promoted has not changed. This network that can be collaborated on on a large scale by strangers will become an important force in promoting global social and economic development. I hope young people can gain something from this documentary.”
