edit: didn’t like my analogy I’d prefer you posted something constructive rather than just saying “doesn’t need blockchain”. Of course it doesn’t. Storing data doesn’t require a relational database, or a key value store either. All have pros and cons. Saying “doesn’t require blockchain” is obvious and adds no value. It’s like coming into a workshop explain what a saw is and saying “other cutting tools also exist”. You seem to be making the leap that because I’m explaining what something is without saying whether or not I think it’s the right move that I think it is. I don’t know whether or not it was cheaper and more effective for JPMC to fork ethereum or to build their own accounting system from scratch and I doubt you have the correct information to make that assumption either. Maybe JPMC doesn’t have a team capable of writing accounting software (seems unlikely). What’s more likely is they are looking for headlines because they know blockchain is hyped technology. It would have probably not made the news if they announced they were adding another settlement system beyond Zelle, ACH, and wire. So, they probably chose this because they think it will reduce costs and move their stock price while building a bespoke software accounting system would have been more costly and wouldn’t have provided as much hype. Businesses don’t make decisions about technology completely based on its technical merits. Many times they choose technology because someone recommended to them, or it’s cheap, or they can’t build it themselves, or that’s not their primary business, etc.

We can make a good guess -- they're already a bank, so they're already running the same accounting system this project requires.

  This system is both accounting and transfers. All their other transfer systems (ACH, wire, Zelle) are run by third parties. As mentioned, we don’t know what the cost of building their own transfer system would be. In the long term, using someone else’s code for your bespoke project typically means you run up against “square peg round hole” issues so it’s likely they are just deferring engineering costs.

    > All their other transfer systems (ACH, wire, Zelle) are run by third parties. Those are systems for transferring money from JP Morgan to another bank. This system doesn't do that; it can only transfer money from JP Morgan to JP Morgan. That is much easier for JP Morgan to do, and they already have their own system for it.

      That is wrong. Please re-read the article.

        OK, I read the article. It says > the coin is only available to JP Morgan’s institutional clients without really expanding on anything. But, JP Morgan has an official announcement out about this, which is much more informative than this article is. It says: > How does it work? > In step 1, a J.P. Morgan client commits deposits to a designated account and receives an equivalent number of JPM Coins. In step 2, these JPM Coins are used for transactions over a blockchain network with other J.P. Morgan clients (e.g., money movement, payments in securities transactions). Finally in step 3, holders of JPM Coins redeem them for USD at J.P. Morgan. and it says: > Only institutional customers passing J.P. Morgan KYC can transact with these coins So, in order to make any transaction using JPM Coins, you need to be a JP Morgan customer who's passed their KYC checks. Parties who are not clients of JP Morgan cannot purchase, receive, or redeem coins. What part of what I said was wrong? What language from the article were you thinking of?

        > Those are systems for transferring money from JP Morgan to another bank. This system doesn't do that; it can only transfer money from JP Morgan to JP Morgan. In theory, anyone who passes KYC can transfer money in token format to anyone else on the network. There is a major issue with the network which is that it seems as if only JPMC can actually redeem the tokens for dollars.
