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 always-on privacy coins that hide everything, Ergo's Sigma Protocols let you prove things about your data without revealing the data itself. You can prove you're over 18 without showing your birthdate. Prove you have sufficient funds without revealing your balance. Prove membership in a group without identifying yourself. This is privacy that works in the real world - where sometimes you need to prove compliance while protecting your details.
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
