MPhil Graduate Advances Cross-Chain Interoperability with Game-Theoretic Innovation

Paa Kwabena Dankyi, a recent MPhil graduate from KNUST Computer Engineering, has developed an approach to distributed systems through his thesis, “Reward-Based Dynamic Leader Node Selection for Cross-Chain Interoperability: A Game-Theoretic Alternative to RAFT.” 

His research introduces a novel game-theoretic framework for leader election in peer-to-peer networks, integrating trust scoring and incentive-driven mechanisms to enable dynamic, efficient leader selection across heterogeneous blockchains.

This innovation improves latency and scalability in cross-chain environments while ensuring secure, reliable communication across blockchain and IoT networks. His work holds strong potential for real-world impact, particularly at the intersection of decentralised systems and the Internet of Things.

He extends special appreciation to his supervisors at the DIPPER Lab–KNUST, whose guidance, mentorship, and unwavering support—especially during the final stages of his research—were instrumental to the successful completion of his work.

Mr. Dankyi’s success was made possible in part through the support of the KNUST Engineering Education Project (KEEP). True to its commitment to academic excellence, KEEP empowers students to achieve their full potential, and Mr. Dankyi is deeply grateful for the encouragement and support he received throughout his academic journey.

He aims to advance research in intelligent distributed systems, AI-driven trust mechanisms, and resilient IoT–blockchain integration. He also plans to explore applications in robotics, electronics, and embedded systems, to develop scalable, secure technologies with tangible, real-world impact.
