Introducing PPAL — The Next Evolution of Identity in Web4
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.
