The word "Bitcoin" has become tainted within culture. Bitcoin is commonly associated with things like Silk Road, MT Gox, ect..all sorts of scandals. So, when marketing bitcoin, people are now talking about "blockchains" and not "bitcoins"
Yeah, I can understand that. But many of these articles say that X bank wants to develop their own blockchain. That's what I don't get...how it would be secured. Plus, it's a central authority which defeats one of the primary purposes of Bitcoin. None of the articles has addressed that aspect either.
It will be secured inside their own private networks by their own servers, as private intranets are secured being somewhat isolated from the internet... R3CEV is developing some sort of collaborative blockchain type project joined by large 25 banks (I'm guessing inter-bank transactions and settlements blockchain)

Who said financial institutions will have to embrace bitcoin blockchain without going through their own painful mistakes and failures first.
