The rating agencies merely track your transactions and provide a source for agencies.
The score is an data model that is refined over time.
This would be the ability to use multiple factors as part of the model (just like big banks currently do) and possibly include non-credit data in the model (like SoFi & Upstart) use.
Time: you need a lot of historic data over time to feed your model before you can claim any sort of accuracy
Public blockchain: Expect someone sucking this up in a firehose and can soon relate an I'd to a physical person. Well, then I'm no better than shitty Equifax...
