This article is the milestone roundup and the thanks letter for the Web3 Foundation program Introduce Gafi Network The last time I write the article on the Heroes and Empires 2021 roundup, I talk about all the goals we achieved and the struggle we faced when we build Heroes and Empire(H&E). At the end of the tunnel, there is the light that I mention about the new technologies that can help us solve all the problems of H&E and other blockchain games, the Substrate. After that, we put our resources to learn and build Gafi Network.
