In Web3, identity is fragmented. Wallets are isolated. Users are forced to choose between privacy and usability. And applications struggle to understand who users are—without compromising decentralization.
PPAL (LEP100-14) changes that.
PPAL—Programmable Privacy-Aware Linking—is a foundational identity primitive within the Lithosphere ecosystem designed to unify identity across wallets, applications, and chains, without sacrificing privacy.
The Problem
Today’s blockchain identity model has limitations:
- One wallet = one identity (not realistic)
- No native way to link multiple identities securely
- Privacy is binary: either fully public or fully anonymous
- No programmable identity logic
The PPAL Solution
PPAL introduces a new paradigm:
- Link multiple wallets and identities
- Control visibility at a granular level
- Program how identity behaves across apps
- Preserve privacy using cryptographic proofs
Instead of exposing identity, PPAL allows selective revelation.
What Makes PPAL Different?
PPAL is:
- Composable → Works across all Lithosphere applications
- Programmable → Identity rules are defined via smart logic
- Private by design → No unnecessary exposure of user data
- Cross-chain ready → Designed for a multi-chain world
Why It Matters
PPAL unlocks:
- Unified user experiences across dApps
- Trustless reputation systems
- Private yet verifiable credentials
- AI agents with persistent identity
Welcome to Web4
In Web4, identity isn’t a wallet.
It’s a layer—intelligent, programmable, and privacy-first.
PPAL is that layer.
