But what about these issues with missing TB?
What happens when SH from 1 to K signs TB, but SH K+1 releases his claiming previous K TBs did not arrive on time? And what if this (K+1)th TB contains transactions conflicting with ones in previous K blocks?
Blockchain does not have any data that would allow nodes to tell 'real' course of action and it would always resolve to some kind of voting between SHs?
