I think that the "who has control of the ledger" question is a serious
hot potato when central banks deal with each other.  This isn't about
their clients and businesses, this is about the fact that they don't
trust each other and want an open ledger that no single one of them, nor
any of the governments they work with/for, can control.

So, no, I don't expect the businesses and ordinary people to ever
see it; this sounds to me like a settlement system to be used
internationally between central banks.
