Developer showcases Kalion, a zero-knowledge proof-based Asteroids game on Stellar that enables off-chain computation with on-chain verification. The project demonstrates how ZK proofs can handle complex, computationally intensive tasks like 60 FPS gameplay over 10 minutes, proving fair play while minting Kalean tokens to winners.
A developer presents Kalion, an Asteroids game built on Stellar using Risc Zero ZK proofs to solve the blockchain scalability problem for complex computation. Protocol 25 introduced cryptographic primitives enabling off-chain compute with on-chain verification. Kalion runs 60 FPS gameplay for up to 10 minutes with physics, deterministic rules, and anti-cheat mechanisms. Game tapes are sent to GPU provers (Boundless Network or Vast AI) which generate Groth16 proofs verified on-chain. Players earn Kalean tokens based on high scores. The project is fully open-source with CLI farming tools, autopilot bots, and extensive documentation. The speaker emphasizes this pattern extends beyond gaming to high-frequency trading, complex financial interactions, and any computationally heavy workload needing fair settlement guarantees.
