Minimal Viable Plasma

If the Plasma operator is enforcing this rule, then there doesn’t seem to be a difference between this and having the Plasma operator refuse to include double spends - users already can’t do anything bad unless the operator is malicious.

I have a question about exited UTXOs. Please correct if the following understanding is wrong.

In Minimal Viable Plasma (ex. GitHub - omgnetwork/plasma-mvp: OmiseGO's research implementation of Minimal Viable Plasma), I think it seems that the child chain does not know which UTXO has been exited, because exit requests can be submitted to Plasma contract directly. So the operator should check exited UTXOs stored in the Plasma contract on the parent chain before accepting transactions on the child chain.
