I think what they are doing with storing people's ID's on the blockchain is to help prevent fraud and also use the "ID" what people chose to give, so Open Bazaar "team" can then allocate a percentage score for the seller, the better the info the higher the score, EG: some people might just store a copy of a utility bill, while other may choose to put a driving licence (or some other higher rated document with a picture).
The ability to be able to store information, such as Identity is going to shake up the internet reselling (along with many more uses, as i posted that link as a example of how ID's stored on the blockchain, can be used for) in a very positive way, it is great to think the Identity Sidechain I/O Coin is working on has got some much potential and it really at the forefront of this new way of helping people to shop online more safely. Plus the other fantastic opportunities that will arise.
One thing that springs to mind is the current situation with the mass immigration in Europe, ho amazing it would be if "immigrants" people who flee their homeland due to wars, could quickly and easily be identified using the blockchain, if would certainly speed up the processing of applications and also give the governments a much more streamlined system when trying to ID people.
Whos ever idea it was to create this Identity Sidechain deserves a medal of achievement. I hope some top government official who deals with immigration learns about the IOC Identity Sidechain and understands how groundbreaking and perfectly it can replace the current, out of date systems that are in place now.
