Paper 2023/472 Deep Bribe: Predicting the Rise of Bribery in Blockchain Mining with Deep RL , Technion – Israel Institute of Technology, Technion – Israel Institute of TechnologyAbstract Blockchain security relies on incentives to ensure participants, called miners, cooperate and behave as the protocol dictates. Such protocols have a security threshold – a miner whose relative computational power is larger than the threshold can deviate to improve her revenue.
