We can avoid computing stationary probabilities on Markov chain, nor stopping times for Poisson processes as in previous analysis. We do apply these techniques to other block withholding strategies in Bitcoin, and then, we consider also selfish mining in Ethereum.0 aOpen access — freely available to read.40uhttps://arxiv.org/pdf/1904.07675v1yRead the full paper (PDF)
