mining-game
coalition-formation

Model Proof-of-Work mining as a strategic game among heterogeneous miners, analyse Nash equilibrium hash rate allocation, simulate 51% attack incentives as a coordination game, and explore mining pool formation through coalition game theory.

Commitment schemes and strategic credibility

cryptography-and-gt
commitment
stackelberg-games
mechanism-design

An analysis of how cryptographic commitment schemes enable credible strategic commitments in games, connecting hash-based commitment protocols to Stackelberg leadership, the value of commitment, and equilibrium refinement through binding mechanisms.

Secure multi-party computation as a game-theoretic problem

cryptography-and-gt
secure-computation
secret-sharing

Model secure multi-party computation as a game where parties have private inputs and incentives to deviate, implement Shamir’s secret sharing in R, and visualize threshold schemes and security guarantees interactively.

Secure Multi-Party Computation and Game-Theoretic Incentives

cryptography-and-gt
secure-computation
mechanism-design

Implement Shamir’s secret sharing and a secure multi-party computation protocol for sealed-bid auctions in R, analysing how MPC enables commitment to truthful strategies and incentive compatibility.

Zero-knowledge proofs — game-theoretic foundations

cryptography-and-gt
zero-knowledge-proofs
interactive-protocols
computational-complexity

Zero-knowledge proofs modelled as interactive games between a Prover and Verifier, with simulations of the graph colouring ZKP protocol demonstrating completeness, soundness, and zero-knowledge properties.
