ZK Gaming on Stellar This hackathon is about exploring Zero-Knowledge (ZK) as a real gameplay primitive — not just a buzzword. Your mission is to build a game prototype that uses ZK for something that actually matters to players: hidden information, fair resolution, provable outcomes, private actions, verifiable computation, or any mechanic where “trust me” isn’t good enough. And don’t overthink the scope of the game. It doesn’t need to be an MMO or a full commercial title — a clean, minimal prototype like tic-tac-toe, Sudoku, Battleship, or a simple card/strategy game is totally valid as long as ZK is essential to how it works (not just mentioned in a README). We’re doing this now because Stellar has taken a big step forward for ZK developers with Protocol 25 (X-Ray), which adds protocol-level cryptographic building blocks like BN254 elliptic-curve operations and Poseidon/Poseidon2 hash functions.
