Z9S is a Metaverse, MMO-based (massively multiplayer online), blockchain-integrated world. Within Z9S Metaverse contain 3 cores (1) NFT items; (2) interactions between users within the Metaverse fully functioning as a second world; (3) contributions from the Community including in-game contents (new features for Z9S) and external activities around the game (streaming, YouTube videos, viral marketing campaigns). All 3 mentioned core principles revolve around 2 tokens of Z9S: governance token - $ZNM and in-game currency token - $Z9C. Therefore, players can earn real profit through playing or building Z9S. In other words, Z9S is a Game-Fi where real players can actually ‘play-to-earn' sustainably.
