In this paper, we greatly expand the mining strategy space, and consider a class of stubborn mining strategies where a miner performs better by taking long shot gambles. Consequently, we show that the selfish mining attack is not optimal for a large parameter region.
Further, we show how a miner can further amplify its gain by non-trivially composing mining attacks and network-level attacks. We show that surprisingly, in some strategies desirable for the adversary, victims of an eclipse attack can actually benefit from being eclipsed!
