From Wikipedia:-
A blockchain – originally block chain – is a continuously growing list of records, called blocks, which are linked and secured using cryptography.
Where is the mention of token here? Blockchain is usually used for storing data in a transparent and secure manner free from any type of unauthorized manipulation. It has potential to disrupt many industries like banks, e commerce, social sites etc by making the storing of data better and secure.
Blockchain can certainly thrive without cryptocurrencies.
Blockchain projects funded by institutions are fine without tokens.
