A comment on Ask HN: Are there any blockchain startups selling a product successfully?.
They manage balances. Sounds easy, just a database column?
The problem with storing balances is securing it against unauthorised users. i.e. Hacker, DB admin.
A blockchain can be used for this, as the requests to change a balance all have to be signed. And it's very hard to re-write the blockchain history.
