Since the birth of Ethereum, public chains have sprung up. However, the lack of business application scenarios makes the story of public chains questionable. On October 24, 2019, the state promoted the blockchain technology to the national strategic level. Blockchain technology has attracted much attention. The domestic public chain has become a hot spot for a while, and the traditional Internet giants have also laid out one after another. The trend of blockchain’s real economy has become unstoppable, and the integration of public chain and alliance chain has become a hot topic. In order to help people understand the current situation and future of public chain more clearly, and provide industry insights for industry peers, Token insight has the honor to invite Qi Zhou, founder and CEO of QuarkChain and other public chain leaders to discuss what changes will happen to the public chain in 2020.
