An Incentive-Compatible Semi-Parallel Proof-of-Work Protocol
Mustafa Doger, Sennur Ulukus
Parallel Proof-of-Work (PoW) protocols have been suggested in the literature to improve the safety guarantees, transaction throughput and confirmation latencies of Nakamoto consens…
Double Spending Analysis of Nakamoto Consensus for Time-Varying Mining Rates with Ruin Theory
Mustafa Doger, Sennur Ulukus, Nail Akar
Theoretical guarantees for double spending probabilities for the Nakamoto consensus under the -deep confirmation rule have been extensively studied for zero/bounded network dela…
Dynamical Dorfman Testing with Quarantine
Mustafa Doger, Sennur Ulukus
We consider dynamical group testing problem with a community structure. With a discrete-time SIR (susceptible, infectious, recovered) model, we use Dorfman's two-step group testing…
Group Testing with Non-identical Infection Probabilities
Mustafa Doger, Sennur Ulukus
We consider a zero-error probabilistic group testing problem where individuals are defective independently but not with identical probabilities. We propose a greedy set formation m…
