Nothing about this requires the blockchain though. It's additional complexity for no gain.
You can do that without a blockchain. Have all those orgs publish their accounts in a form that allows for anyone to make copies and to audit that the published versions don't get modified over time.
I have mixed feelings about banks, national banks, lenders, art trading, casinos, pawn shops and such though. I'm a bit worried about tracking private individuals at that extent because of these.
