Robbed Withdraw
摘要
In this article we show that Theorem 2 in (Lie et al. in Mathematical Research for Blockchain Economy, MARBLE 2022. Springer, pp. 233–251, 2023) contains a gap. We then show that an undesirable phenomenon, which we call the robbed withdrawal, can happen as a consequence. Finally, we provide an almost necessary and sufficient condition for the avoidance of the robbed withdrawal phenomenon and use it to show that Wombat Exchange is safe against the robbed withdrawal.
