In the world of traditional finance, privacy protection and audit transparency are often two opposing forces. How can we protect traders' sensitive information while also satisfying regulatory compliance requirements? This dilemma has long troubled the entire industry.

The Hedger introduced by the Dusk ecosystem provides a practical solution.

Unlike the traditional blockchain approach of "all information publicly available" or "completely anonymous," Hedger adopts a tiered permission management approach. How does it work? The trading parties first generate verification credentials using zero-knowledge proofs. Sensitive data such as identities and amounts are encrypted and uploaded to the chain. Network nodes only need to verify that the credentials are valid, without needing to see the original data.

Next comes the regulatory or auditing phase. They must first submit an official authorization request to the ecosystem, clearly specifying the scope of the audit and the applicable regulations (such as MiCA clauses). They cannot access data arbitrarily. After confirmation from the trading parties or the ecosystem governance nodes, the auditor can retrieve the de-identified transaction data through a dedicated interface. Importantly, the entire data usage process is recorded, strictly following the "least necessary" principle.

The brilliance of this approach is that it blocks unauthorized data leaks while meeting compliance requirements for financial regulation. Currently, this has been successfully implemented in Hedger's Alpha version.

For EVM applications integrated with Hedger, the good news is that there is no need to develop additional audit modules; they can directly pass the EU financial regulatory review quickly. This feature is also the fundamental difference between Hedger and other privacy tools on the market.
