In the digital world, running a business is really troublesome—identity cards, addresses, account information all need to be submitted, and you're worried about being targeted for transfers. Want to follow compliance routes but don't want privacy to be exposed? The tools I've tried are either complicated to operate or their privacy protections are virtually useless. I once thought I had to choose between compliance and privacy.

Until I used DUSK and realized the problem isn't really there. Its Citadel zero-knowledge KYC model completely reverses the approach—you're no longer required to upload ID and address information to the platform; all data is kept in your own hands. When applying for cross-border digital services, I only need to use zero-knowledge proofs to verify "I meet the qualification requirements," without revealing specific identity details. The approval is instant, and the entire process involves no information leakage.

What's even more impressive is the design at the transaction layer. MLSAG ring signatures encrypt your identity and transfer amount, allowing the recipient to confirm the transaction's authenticity and validity, but they can't see who your account belongs to or how much was transferred. Coupled with Bulletproofs range proofs, you can also demonstrate to regulatory authorities that the amounts are legal and compliant—both at the same time.

I've heard that companies using this solution have saved a lot of trouble handling financial compliance, especially in scenarios adapting to European MiCA regulations. As someone with little technical background, I was able to get started in half an hour following the process, and the annual cost is only a few thousand yuan. Now I can confidently handle business and transactions—DUSK is no longer just a privacy tool; it’s more like an infrastructure that helps ordinary people securely establish themselves in the digital economy.
