Good luck getting me to spend my precious universal, uncontrollable, money for some shitty bank coupons. Looks like the banks have passed through the "Bitcoin can't be money!" phase and entered the "I'll create my own alt-coin!" phase. Good luck with that.
And it shall end up like all other alts so far
Reminds me of the intranet fad in the 90s, "this internet thing looks interesting, but we'll create our own safer and controlled version!"
Everyone who make a little reasoning can understand that the (commercial) banks will use blockchain or the technology used to build it,
not for creating their own coins. Everyone which think a little can understand that this is impossible. We will have millions of coins and all the (commercial) banks in discussion with all the other (commercial) banks to accept their coin. So every (commercial) bank will passe all its time in discussion to reach the needed collaboration with all the banks which collaborate about its coin. The same thing for other millions remaining. Then everyone of those will find the way that their coins have legal value. For this needed the permission of the Central Bank of the country. So other discussions with the Central Banks of every country; which will want the "why" of this choice. I can't find one. I think even the banks. So probably this permission cannot be given. In other words, the result will be an imaginable mess and an absurd situation where everyone cannot understand everyone.
Every (commercial) banks it is not so stupid to do or even wonder this. They work with the money and such kind of work need to much intelligence. If they do such work (with money) and survive or have profits from that, mean that are intelligent and not at all stupid.
So, who think that the (commercial) banks are working to know or implement the technology in which is based the creation of blockchain to create a new personal digital coin is in big wrong.
They are studying blockchain to implement its technology not to create some clone or another digital coin. The technology of blockchain, named peer to peer realize, if applied,
big reduction of costs. This is the reason of their study of blockchain. This is the power of peer to peer and from this reason is called disruptive. Remain to be understand the field (within the commercial bank) in which it will be applied but I think that the probability is to high that can be applied firstly at the transactions made from the bank. Aiming to reduce the costs connected with those. Anyhow this is a guess and as such remain to be verified.
It is a totally other thing the question treated from the OP. This is the case of the creation of e new coin. But it will be a coin created by and for the Federal Reserve, which is totally another typo of bank and have totally different duties. The digital coin created by the Federal Reserve (if it will be created) will have legal power. It will be like or will replace us dollar (according to the decisions taken by this bank). Will be owned by the state of USA and will be national legal currency of USA. With or within the us dollar. Will have formal power and will be not like the million other altcoins created by one or a group of developers who, in most of the cases, create the altcoin only to make some money and to forget it.
Everyone will be "forced" to use it. This national digital coin will serve for every relation with the Authorities, in this national digital coin will be every salary of everyone (whether it will be private or public the work which will be rewarded), this national digital coin will be used by every merchant etc. So everyone who want to live normally in USA will be "obligated" to use it. No one will ask to leave bitcoin because bitcoin is regulated in USA. But for sure will use this new digital coin created by and for Federal Reserve.
IF IT WILL BE CREATED AND IF WILL HAVE FORMAL POWER GIVEN BY FEDERAL RESERVE. THERE ARE ONLY DISCUSSIONS. THIS DOESN'T MEAN THAT FOR SURE WILL BE CREATED.
