I have a problem where two parties may each submit transactions from one account simultaneously, kind of like a race condition. Let’s call them $T_1$ and $T_2$. This would result in a chance that the miners will select $T_1$ or $T_2$.
In most settings, this is a problem, but it could be fine in my setting as long as the parties who submit these transactions can see both transactions in the mempool. Would both $T_1$ and $T_2$ be visible to the parties?
