Welcome to PINPON Lab!

The Privacy-Preserving and INtelligent P2P Operations Network (PINPON) Lab is a research group at The King's University focused on developing trustworthy, intelligent, and decentralized computing systems for real-world applications.

Our research brings together blockchain, artificial intelligence, privacy-preserving computing, and peer-to-peer (P2P) networks . We are particularly interested in how these technologies can work together to build systems that are secure, transparent, intelligent, and privacy-preserving .

Our current research includes: Blockchain and P2P Systems, P2P Energy Trading, Privacy-Preserving and Verifiable AI, Zero-Knowledge Machine Learning (ZKML), Tokenization, and Digital Assets.

We welcome students and collaborators who are interested in exploring the intersection of computing, AI, blockchain, privacy, and sustainable technologies .
