As I have said before, you cannot have blockchain without bitcoin, and this article by professor Saifedean Ammous, published in the prestigious American Banker, expounds this fact nicely.
"Men who try and separate blockchain from bitcoin are inevitably software vendors desperately trying to sell their services, trying to separate the inseparable because they can’t come up with business models where they interact directly with bitcoin. They also tend to be statists with a fervent belief in the absolute authority of government and implicit legitimacy of the money it mandates everyone accept in payment."
This is the answer on many threads here, he found simple words to explain why bitcoin have a future, and why trols are trolling.
For now bank sector is without answer, but they will try something for sure. Its just question when and what, probably they already have plans.
Saifedean Ammous never said that you cannot have blockchain without bitcoin. His article neither says that nor implies that:
http://www.americanbanker.com/bankthink/blockchain-wont-make-banks-any-nimbler-1079190-1.htmlHis article merely claims that any non-bitcoin blockchain would be "extremely costly and inefficient." That opinion may or may not be accurate. But you keep putting words in his mouth completely different from what he said.
You also quote this:
"Men who try and separate blockchain from bitcoin are inevitably software vendors desperately trying to sell their services, trying to separate the inseparable because they can’t come up with business models where they interact directly with bitcoin. They also tend to be statists with a fervent belief in the absolute authority of government and implicit legitimacy of the money it mandates everyone accept in payment."
But those aren't his words either. That quote is from some writer at Coindesk:
http://www.coindesk.com/central-bank-fail-digital-currency/ Contrary to that quote, there are many examples of non-bitcoin blockchains. Other cryptocurrencies use blockchain. Anybody can use Google to identify other existing uses for blockchain beyond cryptocurrencies.
Look, professor Saifedean Ammous doesn't have a monopoly on opinions about blockchain. And it's not mature that you say "trols are trolling" just because people disagree with you.
