This helps a lot. It is merely a shared ledger. The magic is that it also can be trusted in the hands of your worse case enemy. This allows dispensing with all forms of intermediary intervention.
After all we trust banks because their capital is so huge as to make yours irrelevant and difficult to confiscate without exponential damage. Now we eliminate people completely and leave the transactions in the hands of the principals only with so called block-chain technology.
Of course this matters hugely. All our money happens to be electronic now to start with. Blockchain allows us to forget the bank.
As noted this is slowly working its way into the whole fabric of the industry and will resolve with no banks and loan brokers handling everything else. Capital pools will simply buy broker generated product.
