Playing around with ZK proofs for games Been exploring how ready the tools are for building client-side ZK games. Started with the simplest thing possible - a number guessing game where the browser proves if you're right/wrong without revealing the answer. Looked at RISC0, Cairo/Starknet, but Groth16 + SnarkJS seems perfect for this. The proofs are so tiny they literally fit in a cast (~256 bytes). Just UI mockups so far, but excited that proof generation works on phones in 2-5 seconds. No cryptography PhD required. Maybe we can finally build fun games with hidden state?
