Machine learning and block chain are those of hot issues these days. I know there are many parts mathematicians get advantages when analyzing machine learning, but I do not see how mathematicians get advantages on block chain technology.
The only mathematical concept I see is the use of hash function, but there is actually no need for improving this hash function and more importantly this has nothing to do with block chain technology itself.
By now, I am considering blockchain technology is purely dedicated to computer scienctists. Still, I am curious if there are advantages for a mathematician if he wants to specialize block chain technology.
