@BurnsPhone @jbaylina @gubsheep Actually, this kind of bit arithmetic range proof is a key component in proving balances are non-negative in privacy solutions, including those used in Zcash, Monero and Ethereum-based systems. It may have helped you already.
@BurnsPhone @jbaylina @gubsheep 实际上，这种位算术范围证明是证明余额在隐私解决方案中是非负的关键组件，包括在 Zcash、Monero 和基于以太坊的系统中使用的余额。它可能已经帮助了你。
