Blockchain is the new Buzz word in the financial industry, and if you want to sound cool or prepare for the future of money, you will have to brush up on your Blockchain knowledge. We laugh at the
people, who think they can create centralized permissioned ledgers and then still call it Blockchain tech. A true Blockchain technology has to be public and permisionless and decentralized. These people
try to look cool and wants to distance themselves from Bitcoin, but they are actually cheap imitations of the original idea, which is the public Bitcoin Blockchain.
