Nebula Duel

About Nebula Duel​

Nebula Duel is an on-chain zero-player duel game built to incorporate the thrills of duels and combat with the joy and gains of Defi. It aims to provide gamers with an exciting and immersive experience that will keep them entertained and wanting more.

Nebuladuel currently operates in two modes. Users can chose to play in mode 1, where they get to duel agains the in house NebulaDuel Bot or they chose to play in mode 2 where they play agains other players in realtime.

Players can purchase characters, and these characters can be minted as dynamic NFTs that can be exchanged or sold on the marketplace. Dynamic NFTs are NFT's whose metadata can be upgraded. This way character attributes such as health, strength, and attack are all in sync on the game and also the onchain NFT's.

For selling or buying these dNFTs, NebulaDuel also Integrates a marketplace where game characters and dNFTs can be traded. This is to make it more fun and worthwhile for gamers, as only real ERC20 tokens can be used on the marketplace, and this token can be sold for $USDT or any other token.

We opt to build Nebula duel on Cartesi due of the high computational requirement needed to run the game. The nebula duel algorithm is complex and will be very heavy for regular blockchain protocols. Also, running the algorithm on regular protocols will be very expensive for players and the team as a whole. Hence, the best option was to take advantage of the huge computational power available on Cartesi.

So the idea is to run the backend on Cartesi, then consume the data from the backend by querying the subgraph.

Finally NebulaDuel also integrates an in-house relayer system to enable players interact with Nebula duel without needing to pay Gas fees. Transactions on NebulaDuel go through this relayer which submits users transactions on their behalf to the blockchain, thereby paying the users gas fees.

What's next​

The next step for NebulaDuel would be to research on Upgradeability models to implement so as to enable us add more functionalities and keep the game more interesting over time as users taste improve. At the same time we fine tune and also add more features/ animations to whats available now.
