The one that springs to mind for me is https://chain.com/ https://chain.com/
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.
