How does ErgoMixer provide privacy?

ErgoMixer uses a CoinJoin++ protocol that allows users to mix their coins with others without trusting a central party. It leverages Ergo's Sigma protocols to create complex spending conditions that ensure privacy while maintaining security.

What are Sigma protocols?

Sigma protocols are a class of zero-knowledge proofs that allow proving knowledge of a secret without revealing it. Ergo's ErgoScript natively supports Sigma protocols, enabling complex privacy-preserving applications without trusted setups.

How do stealth addresses work on Ergo?

Stealth addresses allow receivers to publish a single address while senders generate unique one-time addresses for each payment. This breaks the link between the published address and on-chain transactions, enhancing receiver privacy.

Is Ergo privacy optional or mandatory?

Ergo provides optional privacy features. Users can choose when to use privacy tools like ErgoMixer or stealth addresses based on their needs, maintaining flexibility while ensuring regulatory compliance when needed.

What makes Ergo's privacy different from other chains?

Ergo's eUTXO model naturally provides better privacy than account-based systems. Combined with native Sigma protocols, optional privacy tools, and no trusted setups, Ergo offers a unique balance of privacy, transparency, and compliance.
