Replication Data for: Bitcoin Under Volatile Block Rewards: How Mempool Statistics Can Influence Bitcoin Mining

Bitcoin / MDP + A3C implementation: This repository provides a Python implementation of two analysis tools—one based on a Markov Decision Process (MDP) and one based on Asynchronous Advantage Actor-Critic (A3C)—introduced in the paper. The implementation is intended to evaluate Bitcoin’s security as the block subsidy continues to halve and converges to zero, with a focus on how mempool statistics can influence miner behavior. It models decision-making and incentives under volatile rewards rather than presenting an empirical collection. The scope of the repository is the executable code and experiment framework needed to reproduce and study the paper’s security analysis.
