@Dusk : You do not always need to see everything to trust something. In a lot of real situations organizations need to check if things are working without showing information, like money or personal details. DUSK is made with this idea in mind. It keeps things correct without showing everything. DUSK uses something called zero-knowledge proofs. This means that DUSK can confirm if transactions are valid without showing the information behind them. DUSK transactions can be checked as valid while the information, about DUSK transactions remains private.
The DUSK approach is really helpful for auditors and regulators because it lets them see what they need to see without making everything public. DUSK is different from systems that try to add privacy later on. Instead DUSK makes sure that everything is kept confidential from the start. This makes things a lot simpler. Reduces the risk of something going wrong.
Smart contracts can be run privately. They are still verifiable on the blockchain. As big institutions start to use blockchain they need systems that can prove they are doing things correctly without having to share all their secrets.
DUSK thinks that privacy should be a part of how things work, not just an extra feature that you can add if you want to. This is what makes DUSK so important for people who care about keeping their information private. DUSK is, about making sure that people can use the blockchain without having to worry about their privacy.
