They are required by law to be up and running again in 24 or 48 hours (don't remember exactly) if anything happens, otherwise, they lose their license. So they have a mirrored data center in a different place. It could be cheaper to just run a full node in every office they have (100+). They already have a database, the SFTP part is for partners they work with, other financial institutes. They haven't moved yet because it's an old system and it's expensive to write a new one. Obviously, it's also expensive to write a new one on the blockchain. All I'm saying is it could be considered in the future because you can create a secure, maybe cheaper solution with it. I think that is something that "could" drive adoption because if companies can save money they are more likely to use it.
