Some big banks are gearing up to use a blockchain to track interbank settlements.[1] But this isn't a coin, nor is there mining. It's simply a shared ledger that can't be altered without cooperation between a majority of the parties. All alterations are clearly visible to all parties, which is good for auditing. Only big banks who have signed up for this have active nodes, and they are not anonymous. This is an alter…
Since only the trustworthy bodies can join the party, they can do the job more efficiently by not using any of the trendy blockchain which may technically prevent the fraud but otherwise inefficient. And since there are only banks can join the network, I doubt it can technically prevent the fraud among banks because unlike public cryptocurrencies, it does not give incentives to the banks to spend a lot of computation…

Right, because it doesn't use proof of work, it uses a quorum vote. The banks would still need to form a cartel in order to get a (super)majority of the vote.
