Dusk Network is redefining blockchain infrastructure with the Zedger protocol. This is not just hype about a new concept, but a practical solution to a longstanding industry challenge—how to meet compliance and audit requirements while protecting user privacy.

Traditional public blockchains either excel at privacy or transparency, but rarely both. The hybrid privacy model adopted by Dusk breaks this binary choice.

**How does the Isolated Byzantine Agreement (SBA) work?**

Dusk divides network nodes into two layers—the verification layer and the privacy layer. The verification layer uses BFT consensus to process transaction validity, achieving fast block times (3 seconds per block). The privacy layer employs zero-knowledge proofs (ZK-SNARKs) to conceal sensitive data. What is the result? Auditors can see transaction links and verify compliance, while users’ specific private information remains hidden. Empirical data shows that compared to pure PoS solutions, this mechanism reduces energy consumption by 70% and enhances resistance to Sybil attacks by three times. CertiK has already approved the security audit.

**How is cross-chain transfer privacy addressed?**

The answer is the Secure Tunnel Swap (STS) protocol. When users want to transfer USDC from Ethereum to Dusk chain, traditional methods expose transaction details, including amounts, during the process. STS differs—using atomic swaps and homomorphic encryption, users only need to disclose an amount range (e.g., "$10,000–$100,000"), with the exact value hidden via zero-knowledge proofs. This approach fully complies with GDPR’s data minimization principles. Currently, STS supports interoperability with major chains like Ethereum and Solana.

The significance of this technical solution is that privacy and compliance are no longer mutually exclusive. Web3 applications can both protect user data and meet regulatory requirements.
