According to what you explained, block chain is good in the process of ID verification. It should be able to handle different types of ID in an efficient way.
However, we probably cannot use block chain for online voting. Or, to be more accurate, online voting itself could not assure the fairness of election. The issue does not lie on the technology part, but on the human part.
Technically, with the use of block chain or some other things, we are able to make sure that the transmission of information is secured.
When it comes to the human part, there is one important voting standard that could not be met by online voting: a voter's voting process should not be witnessed by any second person, so that the second person knows how the voter votes.
Think about this scenario. John wants his classmates Mike and Tom to vote for politician Richman, and offers 20 bucks to each of them. If it's a traditional voting process as what we have now, Mike and Tom vote in private booths at the voting station. John is not able to verify whether they actually vote for Richman as they promised.
However, if the voting takes place online, John would be able to sit next to Mike and Tom in front of their home computers, witnesses they vote Richman on the screen, then pays them 20 bucks each.
