Play Guide Walkthrough & Setup
CosmosSDK PvP is a Minecraft server launched on Juno (not affiliated with Mojang Studios)
The idea is as follows:
- A Duels Minecraft server (Player vs Player)
- Each player bets X amount of a token (JUNO or axlUSDC)
- These are then deposited into an escrow contract on behalf of both.
- Once both accept, they are teleported into an arena to fight.
- After the battle is over, the loser's tokens will be available for redemption from the winner.
This will be done by modifying my integration plugin found here
https://github.com/Reecepbcups/craft/tree/master/minecraft-integration
This plugin is now in the standalone repo
https://github.com/Reecepbcups/cosmos-minecraft-integration
(Hetzner Cloud VPS or Dedicated).
