In the old days before the 1980s for sure, bank loans were done based on relationships - the bank manager knew you and had your business. That worked for some, but many loans that could have been weren't issued due to not having a more industrial process. In this modern era, lending officers can see your credit scores and a bunch of data to evaluate the risk of default. Even though I haven't seen the inside of my bank since 2010, I can easily get a loan based on credit data.
I struggle with why would I want to issue loans without either the data or the relationship. Maybe if you have a way to get a person's collateral and credit data on chain via a proxy, you can use that to issue a loan. But that seems like our existing structure with just extra steps...
