An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems
International Economic Review, EarlyView.ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

Parallel Algorithm for Approximate State Graph Exploration With Restricted Memory Footprint
Concurrency and Computation: Practice and Experience, Volume 38, Issue 1, January 2026.ABSTRACT We investigate the performance of algorithms that explore large state graphs of finite state machines without input by following paths. To improve on anchor‐based and candidate‐based explorations and to avoid the performance overhead of full anchor lists and the tuning sensitivity of timeout‐based methods, we propose and analyze exploration ...
