On April 17th, Ethereum core researcher Danny Ryan said in an interview that Ethereum hopes to achieve resistance to quantum computing within three to five years. He expects Ethereum 2.0 to be put into use by the end of 2019 or early 2020. The new test network is scheduled to be put into use in the next quarter. Ryan said: "One of our design goals in Ethereum 2.0 is that there is a reliable way to achieve resistance to quantum computing for at least three to five years." He also said that he and his development team plan Ethereum 2.0 was launched in phases.
