Maybe it would be better first to try to answer all the ones you can and only
then really write. Because this is the major part of the thesis!

Again: with what assumptions? Who has to be trusted? How reliably is a block
going to be found?

Does this work also with the "local store" model?

Urn-5: think about it as a very unique keyword.

Which ones?

It is similar to c) but not the same.

Not a satisfactory answer.

They all are important. Maybe you should really try to work on that chapter
first.
