no mass exit problem
no need for semi-trusted operator

there is a bunch of things similar to plasma:

deposit and exit (but simpler)
tx structure and contract execution can be the same

Scope

look through all optimistic rollup implementations, pick the best
sketch a scope of: which code would need to be added, which one changed?

Deliverables

estimated effort to convert Leap implementation to optimistic rollup.

Gain for the project

reduced complexity of infrastructure
