Why would they even need a blockchain to move money between themselves?
it's unclear to me as well. even if you have a (semi private) public ledger,
it doesn't need to be a blockchain as the units are fiat debt instruments,
not scarce digital assets like Bitcoin.
It's simple guys:
If Barclay's (or any bank for that matter) developed their own block chain that means they would develop their own software and here comes the BarclaysCoin (in a way).....
I will not focus on the BarclaysCoin, but I will focus on what they have already considered -
saving huge on payroll.
Right now Barclay's has 7000 branches worldwide [1].
(Before you read further keep in mind that the numbers I am using it's just examples and may and probably will not reflect to real life data)
Now, let's say that on average there are 10 employees in each branch that get on average $2000 per month salary (plus insurance, etc).
That is a total of:
$140 Million Dollars per month!!!Now, back to the block chain:
If they have their own block chain and client software they will effectively be able to gradually lower their branches (not the electronic banking) payroll expenses to
$0 Dollars per month!!! And that can be achieved simply with the use of Satoshi's technology.
With the use of a block chain and client software there will be no need for cashiers, the customer can deposit and withdraw FIAT through an ATM and transactions will be made within the client software.
Does the above sound like a possible scenario to you?
