Is Stubborn Mining Severe in Imperfect GHOST Bitcoin-like Blockchains? Quantitative Analysis. (arXiv:2302.00210v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
GHOST, like the longest-chain protocol, is a chain selection protocol and its
capability in resisting selfish mining attack has been validated in imperfect
blockchains of Bitcoin and its variants (Bitcoin-like). This paper explores an
analytical-model-based method to investigate the impact of stubborn mining
attack in imperfect GHOST Bitcoin-like blockchains. We first quantify chain
dynamics based on Markov chain and then derive the formulas of miner revenue
and system throughput. We also propose a new metric, "Hazard Index", which can
be …
