Let me guess: they want to copy Bitcoin but not everyone can participate
(only approved banks). They want to copy bitcoin but not everyone can mine
(only major banks). They want to copy bitcoin but not everyone can see all transactions
(filter to your own transactions only?). Yeap, it will end up with a close system in a centralized database just like they have right now.
Bitcoin is about losing control to anyone and open access.
- - If not everyone can participate they will remove the consensus code and add some sort of centralized authentication.
- - If not everyone can mine it they will again have some sort of centralized authentication.
- - If they remove the mining entirely, the currency creation will be either pre-mined with some banks at start or distributed based on a some specific rule that will favor the big starting banks. Having no mining will also remove all incentive to validate the transaction, make the whole thing weak and prone to double spend attack.
- - If they don't want everyone to see all the transactions, it will be close network with restricted access. A single bank could leaked out the entire blockchain, I'm not sure they really want to go in that direction!
