Our decentralized application (dApp), named Mississippi, is a fully on-chain PVP roguelike game, whose innovation lies in introducing new modes of interaction and solutions to technical challenges within the blockchain gaming sector.

### Innovative Utility or Service:
- **Fully On-Chain Operation**: Unlike the current state of GameFi, all game logic and data in Mississippi are stored on the blockchain, ensuring transparency and fairness in the gameplay process.
- **Privacy-Protected Real-Time Communication**: Achieving real-time communication with privacy in player-versus-player (PvP) battles is a significant technical challenge. We have independently designed a "commit and reveal" mechanism to ensure the encryption of player strategies, preventing front-running actions by viewing on-chain data, thereby enabling fair and effective competition.
- **Interoperability with On-Chain Assets**: By "extracting" equipment from loot, which grants players specific attributes for each round, such as increased speed from boots. We are pioneering Autonomous Worlds by integrating with existing game assets and logic, such as Lootverse, and experimenting with co-creation with regular players.

### Problems Solved or Needs Addressed:
- **Enhanced Interactivity and Fairness**: By deploying the game fully on the blockchain, we offer a fair and visible gaming process different from traditional centralized server games, solving the problem of cheating and increasing trust among players.
- **Enhanced Player Engagement**: By allowing players to form alliances for collaborative construction, transportation, warfare, and customize their management approach, and even build their on-chain states, we have added depth and increased player engagement in the game.
- **Technical Innovation**: By solving the technical challenges of real-time communication and privacy protection in PvP battles, Mississippi brings innovative solutions to the blockchain gaming sector, promoting the application and development of blockchain technology in gaming.

In summary, Mississippi is not just a game; through its innovations in blockchain technology and smart contract applications, it addresses the issues of transparency and fairness in games, while providing players with a new world full of challenges and fun, showcasing the vast potential of blockchain in the gaming sector.
