Privacy on Ergo
Programmable Privacy with Sigma Protocols
Core Idea
"Privacy is not about hiding. It's about control."
Ergo takes a unique approach to blockchain privacy: optional, programmable, and provable. Unlike privacy-by-default chains, Ergo's Sigma Protocols let you prove statements about data without revealing the data itself. You can prove age ranges, balance predicates, or group membership while minimizing disclosure. That supports selective-disclosure workflows, though actual legal compliance depends on jurisdiction, implementation, and the surrounding service provider.
Why Ergo Is Different
Most privacy solutions force a binary choice: full transparency or full opacity. Ergo's Sigma Protocols enable selective disclosure - reveal exactly what's needed, nothing more. This isn't just academic cryptography; it's built into ErgoScript as a first-class primitive. Every smart contract can incorporate zero-knowledge proofs. ErgoMixer provides non-interactive, non-custodial mixing. And because privacy is optional, Ergo remains accessible to regulated entities while empowering individuals.
Key Differentiators
Sigma Protocols: native zero-knowledge proofs in every smart contract
Selective disclosure: prove statements without revealing underlying data
ErgoMixer: non-custodial, non-interactive token mixing
Programmable privacy: build custom privacy logic into dApps
Optional by design: transparent when needed, private when required
