摘要: Proof of Work (PoW) powered blockchains currently account for more than 90% the total market capitalization existing digital currencies. Although security Bitcoin has been analysed extensively, most analyses use restricted models that do not take parameters such as network delays or block intervals into and allow a comparison different blockchain instances with consensus parameters. In this thesis, we provide quantitative framework based on Markov Decision Processes (MDP) to analyse PoW various against selfish mining double spending attacks. We devise optimal adversarial strategies double-spending real world delays, sizes generation capture through stale rate consider impact eclipse Additionally, perform practical analysis Ethereum Stellar where describe vulnerabilities in discuss current state network.
