The staking mechanism reminds me of LP. More u buy off the pool more commission goes to the provider. And here, more is locked away for staking, much reward u can potentially grab. What concerns me is how can we change the code to be able to drain the coins being staked from the network to a personal wallet. Squeamish face of yours must have found a way to somehow exploit the network when it reaches maturity or great usage.
Please formulate your question more precisely. UMI does not support stacking so it is not clear what do you mean and what information you would like to find out.
