Metale(ex.Read2N) is a Web3 lifestyle application that has built-in Game-Fi and Social-Fi elements. Users could prepare NFT for themselves in the form of books. Users could obtain game tokens by reading relevant books and these tokens could be either used in the game or converted into cash. Through Game-Fi, Read2N aims at encouraging hundreds and thousands of people to read and create the DAO of certain literature as the "governance content". Each time of reading would enhance the consensus of this literature in nowadays world and help the author or the producers of the derivative works to construct the corresponding metaverse with this consensus.
