StellarDev collaborated with NFT Worlds to create an unparalleled survival multiplayer experience on Minecraft, supporting an unprecedented number of players. We achieved this by rewriting essential elements of Minecraft to ensure stability, without affecting standard gameplay mechanics. Our efforts paid off as we successfully handled peaks of over 4,000 concurrent players without any issues, while ensuring that standard gameplay remained unaffected. Additionally, we incorporated a playtime tracking system that accurately recorded players' time in the game, which could not be bypassed by malicious players. Players were also rewarded for their playtime.
