Project Description

A decentralized roulette platform focused on ensuring fair play, privacy, and trust using Nillion and Sign protocol.
There are 2 parts to this projects:

1. Securely play roulette and other casino games, with all computations happening securely and privately on Nillion. Also attesting each move in Blackjack by using Sign Protocol, and our custom schema hooks help us attest each move by knowing current and previous move of the user.
2. When the user logs in our application, we query data from our schema to check whether the user is banned from our application or not. Also, we take care that malicious users cannot access the user's IP address and wallet address, by using nillion to securely compute the hash of users' details, and returning only the hash.

What problems does your project solve? How does it preserve privacy for users?

The online casino industry has grown significantly, attracting millions of users worldwide. However, with real money at stake, concerns about fairness and cheating often arise.
Users may worry whether the games are manipulated or if their personal data is secure. Similarly, game developers face the challenge of ensuring trust in their platforms while combating potential hackers and cheaters.

How does the project use Nillion? Describe and link to any Nada programs

We have used nillion's blind computation protocol to store the user's bet details and the array of possible winning combinations (dependent on the number on which the ball is going to land in the roulette). Then the nada_secret program processes these variables and the result of the spin is returned. This removes a major vulnerability, as the bets of the users are handled secretly and blindly in the nillion-devnet.
Apart from this blind computation, we have also added a feature of hardware banning. In this we extract the player's respective ip address and wallet address, and send it to the nillion-devnet for generating a unified harware ban identifier, and then store it. This way, no sensive personal information about the players is revealed, as after the secure computation, only the hash is retured back, which is publicly visible.
We used these nada programs

Is there anything else you want to share?
