This is exactly correct. Private blockchains create efficiency between large institutions like JP Morgan and other banks who are constantly moving large volumes of money around by eliminating the traditional processes in place required to move that money. A private blockchain is essentially a shared database (distributed ledger) used by an arbitrary number of private institutions, each of whom has an interest in participating to reap efficiency gains by using a shared database that they can trust, more than they would trust a traditional database owned by a single party. It's not game changing innovation in the same way that crypto futurists think of Bitcoin as a new type of decentralized money, it's incremental efficiency for existing processes. It's more accurate to think about this as blockchain technology for JP Morgan than as cryptocurrency in the sense that Bitcoin is an application of blockchain technology. JPM coin is not like Bitcoin, or ripple for that matter.

The important thing to understand here is that JP Morgan thinks about blockchain technology completely differently than libertarian futurists. Blockchain is not a movement for them - it's a technology that reduces friction for things they are already doing.

> it's a technology that reduces friction for things they are already doing.

And there lies the rub, because as far as I can tell, this particular (and no particular) blockchain implementation does not in fact reduce any friction for things they are already doing.

I know people who have worked in this space (fintech permissioned blockchain). Although this was my initial reaction, they tell a different story. One angle to that is along the lines of "you wouldn't believe how bad the thing they use now is".

This is the aveneue of questioning I'd really like to see more detailed discussion on. [Disclosure: I'm agnostic on the potential of blockchain]

Does TPS increase non-trivially in a private chain vs a public chain? If not, will a private chain's TPS at least substantially outpace the TPS of, say, Ethereum within 3-5 years? That is, will JPM's private chain reach 100, or 1k, 10k, 100k, etc TPS?

Assuming TPS reaches a sufficiently high-level (whatever that could be), would a private chain require fewer sysadmin/engineering/etc. folk, compared to what the DTCC model requires?

Does a semi-private chain (where JPM allows other partners or competitors to plug-in) have a faster on-ramp? That is, would it be faster to plug players in than a traditional solution?

Is there a cost reduction somewhere within the audit process? Other processes?

I have these types of questions, but it is difficult to find much substantive discussion on them. Typically, answers are Yes or No, but with little to no detailed explanation as to why.
