accounting

While blockchain theoretically unlocks "triple-entry accounting", hashing all accounting activity to a public ledger is problematic for businesses. 

Application of ZKP feels like the solution, but trust of the tech and practical implementation is a massive hurdle.

Has anyone seen interesting ideas on this front?
