Block chain is an interesting technology, and I think there is likely to be some use case that it's perfect for, but every time I've actually looked at a use-case that it's been implemented in thus far I haven't been able to figure out how the blockchain element is actually providing anything that traditional methods couldn't, or really anywhere that it's providing any value.
The other day I came across a post on reddit about somewhere (want to say france) using blockchain with identifiers marked on cartons to prove the provenance of eggs. Who knows how much money was spent on developing the whole system when all it can do is cryptigraphically verify that yes, indeed, that box has a valid QR code, ignoring the fact that you can't cryptographically verify an egg. As far as I could tell the system had exactly the same functionality as if you assigned each carton a GUID.
Of course, crypto currency comes to mind, but the privacy implications and scalability issues that come along with it make it more of a liability to sustained growth in my view.
I don't think that blockchain isn't worth learning at all, especially if you're interested, but if you're trying to brush up your professional skills and looking for way to increase your marketability, blockchain is just about the last place you want to be unless your goal is to work at a tech-bro startup that is going to be bankrupt in a year.
Someone will make something useful with blockchain at some point and it may become a valuable skill, but at the moment it's a skill that is going to give you more street cred than actually advancing your career.
This.
