Supply Chain Management
I think this is your best bet, as it's one of the best implementations of a blockchain.
Imagine being able to trace your steak back to the farm where it was raised, see the food it was given, see where it was killed, and if any sickness was there at the time, etc. I believe IBM is working on this.
That is the best idea so far Vod! I was talking to my supervisor exactly about this and we can actually go ahead and see if there are existing papers on the same topic. The goal is to publish a paper which will be accepted by IEEE/IFAC organisations.
I would suggest you consider the "Identify Approval on Blockchain". The reason is that going for what Vod has suggested means that you would be researching what some other companies have gotten to the stage or deploying and not only IBM, I had read about LG planning something like that and for words to get out about it, they must have tested it and be sure its a workable solution at the minimum.
Identity verification of the other hand, seems a global problem that have not been solved yet despite the several verifications that have been put in place by various technologies that have come before now and you could be a front line that would be consulted for implementation considering the problem is being faced by both the private sector and public sectors.
As much as I would like to work on that problem, I equally hate the fact that this leads to giving up on the anonymity. The concept really has it's commercial advantages but I'm a bit against with validation inside of a free ecosystem.
Agree that supply chain management or logistics very useful applications, but am afraid there are many projects already doing this, with several PoCs already trialled. Then again, you could use this to your advantage by examining all the case studies and make good comparative analyses.
Another one states are hot and heavy for are electoral rolls, with also several trials concluded or ongoing.
Personally am most interested in accountability uses for charities, especially in the field, with growing popularity for cash-based aid. The UN has at least 7 blockchain trials (5 for supply chain/logistics).
Lots of material for you. I'm also doing something similar, ir considering, but my area is a bit less well trodden (refugee studies) so maybe identity an area for me.
Sounds great! Maybe we should keep in touch and help out each other during the research? Like peer-to-peer reviews.
Message me your telegram or something if you're okay with it.
