The problem ERummy solves

The ERummy's contract designed for generating and shuffling a deck of cards on a blockchain platform significantly enhances the online experience of playing Indian Rummy. This popular card game, often played between 2 to 6 players, hinges on fair and unbiased card distribution, which is a challenge in digital formats. By leveraging Fully Homomorphic Encryption (FHE)-based blockchain technology, the contract ensures a provably fair shuffling mechanism. The use of on-chain randomness guarantees that the card sequence is both unpredictable and tamper-proof, addressing key concerns about fairness and integrity in online gaming.

Moreover, the transparency inherent in blockchain technology allows players to verify the authenticity of the shuffle and deal, fostering trust in the game's digital ecosystem. This is particularly important for Indian Rummy, a game that relies heavily on skill and strategy, where the secrecy of each player's hand is crucial until cards are revealed during gameplay. By ensuring that the card distribution is both fair and secure, the contract considerably elevates the reliability and enjoyment of playing Indian Rummy online. This approach not only benefits Indian Rummy but can also be adapted for other card games, making it a versatile solution for online card gaming platforms. With this innovation, players can enjoy their favourite card games with the enhanced assurance of fairness and privacy, bringing the traditional card table experience into the digital age.

Challenges I ran into

While developing the blockchain-based card shuffling solution for Indian Rummy, one of the primary challenges encountered was ensuring true randomness in the card distribution process. Traditional methods of random number generation on blockchains often fall short in terms of security and unpredictability, which is crucial for card games that depend heavily on fair play. To overcome this, the project leveraged the unique capabilities of Fully Homomorphic Encryption (FHE)-based blockchain technology. This approach allowed for the generation of cryptographically secure random numbers, ensuring that the shuffling process was both fair and tamper-proof. Another significant hurdle was adapting the card shuffling logic, traditionally written in languages like JavaScript, to Solidity's unique programming environment and constraints. This required careful rethinking of data structures and control flow to fit within the gas limitations and syntactic requirements of Solidity. The solution was achieved through a combination of innovative coding practices and a deep understanding of blockchain technology's nuances. This meticulous approach not only solved the initial challenges but also set a new standard for implementing card games on blockchain platforms, ensuring an enhanced level of trust and fairness in online gaming.
