If the balance is negative enough to subtract from any real users balance it will be visible to at least that user.

- patio11 13y agoI pre-compute two trees T1 and T2, which sum to my claimed total. T1 has a fake user with a negative balance who is visible to @nullc. T2 has a fake user with a negative balance who is visible to @legit_user. If I show @nullc T2 and @legit_user T1, you will both perceive my books as balancing, unless you collude with each other. I can greatly reduce the odds of you successfully colluding by choosing @legit_user to be someone who, e.g., has not logged in in a year, or who hasn't ever bothered to open this verification page.

People should really go read the original discussion. One fun way to address the root commitment is to just commit to it in the coins being proven in the balance.
