Who is mining? If it is just the bank people mining, than I don't see, why they would need a blockchain.
Who can look at it? If it is just the bank people looking at it, than I don't see, why they would need a blockchain.
Is there a white paper about it? Are they actually know, what they are talking about, or are they just throwing around words?
Blockchain technology could be useful for banks. I guess that would be only a distributed transaction processing system what would make transaction processing more resilient, faster and cheaper. But if they release a coin as well, they can use that as an internal or intra-bank currency with some pre-arranged exchange rates to local currencies so they can save time and money as they can use their own common currency when doing business between each other, and with the automated transaction of Ethereum they can automate the whole procedure, so no human intervention needed.
Yes, there is CoinDesk article on the subject: http://www.coindesk.com/global-investment-banks-back-blockchain-initiative/
They may just create interbanking blockchain accepted and supported by all the financial institutions (governments approved). Lol. At least they are finally embracing blockchain tech.
