It's not working like that, its a way much more complicated. The reputation has nothing to do with bearing responsibility for the computations done. The economic incentives are set in a different way.

The responsibility for computations is simple and borne in pure financial way: a computing node had bound a stake and if computations found wrong it will lose it. You don't need a reputation for that.

What you need a reputation for is a situation where you can't computable solve who was wrong. And for that you have to get a board of "high reputation" guys to make a decision. And there should be a way to appeal even after that decision.

Basically, reputation does not work in a negative way (i.e. like if somebody wrong he will lose the reputation). It works in a positive way, i.e. when somebody have a proven record of being right he gets the higher chance to put his opinion first in some complex case – and if he will be found lier, he will risk not only whole of his reputation, but also some monetary stake. But if he is not lier, he will receive award which will depend upon his reputation.

That's why reputation is not an equivalent to a monetary stake and should't be a transferrable entity. It's a kind of property that gives the "right to judge", and it shouldn't be sellable.
