Yes blockchain has good name among all new inventions, blockchain is being use in so many fields now
In what fields is the blockchain technology currently being used? I personally haven't seen much of this at all. Most of what you read is either hot air or just a marketing stunt because blockchain has become a buzzword.
People with understanding of blockchain and no direct bias because of their investment know that it's not better than a database. Brad Garlinghouse even said that it's less efficient than a database, and he knows his shit better than anybody else.
Correct, there are not many fields that currently uses blockchain, I suppose people think that it has million uses because of million ICOs saying that.
Completely right, about database.
This is another widely spread misconception , blockchain can not be used as database in most cases, it will just be too " heavy" to be rational to use. But it can be used as additional component to databases , to make a hybrid database .
