As an underlying currency, there is nothing stopping other businesses creating a competitive market, just as businesses use fiat currencies in the old economy to service their profits and losses. From a business viewpoint, blockchains are a great opportunity for businesses that are willing and able to adopt them. Databases with immutability create transparency between businesses and their consumers, so much so that there is no longer a need for trust.
