The main pillars of his research include: consensus analysis and modelling (looking at the quality of consensus achieved in real-world situations, the effects of incentives and inequality effects of reward distribution), cryptoeconomics inequality, centralisation, asset circulation and hoarding), large-scale blockchain analytics and forensics, design of token-based economies.
