The blockchain has near infinite potential/applications beyond Bitcoin, if banks are trying to get in on it, it's safe to say that it's very solid tech. Also, Satoshi was nominated for a Nobel Prize for his work on Bitcoin and usually they only award these for truly game-changing achievements. (In the end, they decided Satoshi was not eligible since his identity is not known.)
It might sounds bizzare today but Adolf Hitler was nominated for the Nobel Peace Prize in 1939. A lot of strange and odd individuals were once 'nominated' for Nobel Prize.
Nobel nomination is nothing fancy, you can be nominated because someone in Swedish Parliament likes you.
