Hold a PhD Degree

I am a researcher in the domain of blockchain and cryptocurrencies.  After working almost 10 years in this domain, I can say that the potential of blockchain hasn't been used in non-financial sectors. And turns out to be major failure of the technology.  Apart from cryptocurrencies, the second major application of blockchain today seems to be tokenization. And it is also mostly confined to the financial sector. However, through non-fungible tokens, digital artists are able to make some revenues out of it.
