One Privacy Layer, Three Primitives

Stealth Addresses

Unlinkable recipients

One-time addresses per interaction. No one can link your wallet to your activity.

Pedersen Commitments

Hidden amounts

Cryptographic commitments hide values while remaining mathematically verifiable.

Viewing Keys

Compliance without surveillance

Selective disclosure lets auditors verify without exposing data to the public.

From Exposure to Revival

11 categories died because users were exposed. We're building the antidote.

The Problem

Transparent blockchains expose everything

The Solution

One privacy layer with three primitives

The Result

Dead categories come alive again

11 Sponsor Tracks

Every Dead Category, Resurrected

Each sponsor track gets a dedicated privacy application built with real cryptography — not mocks, not simulations of the core primitives. Click any track to see the full death & revival story.
