As I wrote above, there is really solid proposal to fix this issue: https://gist.github.com/callebtc/ed5228d1d8cbaade0104db5d1cf63939
It doesn't seem to be a definitive solution yet, but it's a way forward.
I would not use the word "proof" alone since it gives a false sense of security, because the exact value of the outstanding balance cannot be verified. What can be verified is that this amount is within a range.
