I have build a multiplayer Blackjack game on the blockchain with one smart contract using Phoenix Solidity for data encryption and privacy. Web3.js and React with Tailwind CSS will handle the UI for smooth player interaction.
I have deployed a multiplayer Blackjack game on the blockchain using a single smart contract that integrates the Phoenix Solidity library for encrypting sensitive data. The smart contract handles the entire game logic, including dealing cards, tracking bets, and determining winners, while ensuring that private information like players’ hands remains secure and hidden. This setup allows players to trust that the game operates fairly and securely on the blockchain.
The front-end of the game connects to the blockchain using web3.js or ethers.js, while the interface itself is built using React and styled with Tailwind CSS for a user-friendly and visually appealing experience. Players can join games, place bets, and view results in real-time, with the blockchain managing all interactions in the background. The use of Phoenix encryption guarantees that private data is never exposed on the public ledger, adding an extra layer of security, which is crucial for a blockchain-based game. This project balances the transparency of blockchain with the privacy needed for multiplayer gaming, offering a secure and fair platform for players.
I started with creating the smart contracts using solidity, Fhenix (FOH.sol) hardhat, and then deployed on sepolia for testing. Then, created the frontend with reactJS and Tailwind. At the end, used Helium PoW Faucet to get the tokens for Fhenix testnet and deploying the smart contract over there.
