Privacy

Privacy on Ergo is broader than ErgoMixer. This hub collects live tools, proof-of-concept protocols, user-facing guides, and technical foundations without adding every privacy-related page to the sidebar.

Some entries below are not listed directly in the sidebar because they are research notes, proof-of-concept pages, historical projects, or cross-section references. They remain discoverable here and in the full project directory.

Tools & Projects

| Page | Status | What you'll find | | --- | --- | | ErgoMixer | Live / runnable | Non-custodial mixing, Android guide, safety notes, identifiability notes, FAQ, and token page. | | SigmaJoin | Proof of concept | Research protocol for outsourced, non-interactive mixing based on ZeroJoin ideas. | | SCypher | Unverified project | Blockchain-hosted seed phrase encryption and recovery utility; security/privacy-adjacent rather than a transaction privacy tool. |
