And as agents move onchain, identity is no longer just for users—it becomes essential for systems that act, interact, and execute autonomously.
What You Can Build with PPAL
With PPAL, developers can build:
- Unified user profiles across dApps
- Reputation systems
- Sybil-resistant voting
- Private credential verification
AI agent identity layers
For agents specifically, this enables:
- persistent identity across applications
- verifiable behavior over time
- controlled interaction with contracts and systems
Key Capabilities
1. Identity Resolution
Developers can query a user or agent’s PPAL identity:
- Resolve linked wallets
- Check permissions
- Verify attributes
For agents, this means systems can:
- recognize trusted agents
- validate capabilities
- ensure correct interaction flows
2. Permissioned Access
Access can be controlled programmatically:
if (user.hasVerifiedCredential(“KYC”)) {
allowAccess();
}
This extends naturally to agents:
- allow agents to act within defined limits
- restrict execution based on permissions
- enforce rules across applications
Agents operate with defined authority, not unrestricted access.
3. Selective Disclosure
Applications can request only what is needed:
- Age verification
- Token ownership
- Reputation score
Without exposing:
- Wallet balances
- Full transaction history
For agents, this is critical.
They can:
- prove eligibility
- verify trust
- execute tasks
Without revealing sensitive data or strategies.
4. Cross-App Identity
With PPAL:
- One identity works across applications
- No repeated authentication
- Seamless user and agent onboarding
For agents, this means:
- persistent identity across systems
- continuity of behavior
- reusable trust and reputation
Agents don’t restart from zero—they evolve.
Example Use Cases
DeFi Protocol
- Accept users or agents with verified liquidity history
- Maintain privacy of wallet balances
- Prevent bot attacks using identity scoring
Agents can:
- execute trades within defined limits
- build verifiable performance history
- operate continuously across markets
GameFi
- Persistent player identity across games
- Transferable achievements
- Anti-cheat reputation systems
For agents:
- AI-driven characters with identity
- persistent progression
- verifiable interaction history
Integration Stack
PPAL integrates directly with Lithosphere infrastructure:
- Lithic contracts (.lithic)
- EVM compatibility layer
- DNNS identity resolution
- LEP100 standards
This allows developers to build applications where:
- identity is structured
- execution is controlled
- interaction is verifiable
Across both users and agents.
Why Developers Should Care
PPAL reduces:
- friction
- redundancy
- security risks
And increases:
- user retention
- trust
- composability
For agent-based systems, it enables:
- persistent identity
- verifiable behavior
- scalable interaction
Final Thought
Identity is no longer just a user feature.
It’s a system requirement.
As agents become active participants onchain, developers need:
- identity that persists
- permissions that are enforceable
- interaction that is verifiable
PPAL provides that foundation.
Identity is no longer something you build around.
It’s something you build on.
