Built with World ID

Privacy-preserving human review workflows powered by World ID.

AppealLayer uses World ID to help companies receive appeals from verified humans without turning the process into KYC, a public identity check, or a crypto-native trust exercise.

Positioning

What AppealLayer can say

Built with World ID. Powered by World ID. Built for the World ecosystem. Those are accurate and strong.

Positioning

What AppealLayer should not say

Not endorsed by World, not World-certified, and not built by World unless that becomes officially true later.

Positioning

What goes on-chain later

Only cryptographic receipt hashes and Merkle roots. Never statements, evidence, reviewer notes, or raw nullifiers.

Positioning

Independent by design

AppealLayer is an Enstellis SRL product and is not operated by, endorsed by, or officially affiliated with World Foundation, Tools for Humanity, or World.

Privacy model

World ID provides the primitive. AppealLayer provides the workflow.

The user proves unique humanness. AppealLayer binds that proof to a specific decision, enforces one-human-one-appeal logic, and hands the company a clean operational case to review.

Users prove they are a unique human, not who they are.
AppealLayer should not store raw nullifiers in normal application tables.
Private appeal details remain off-chain even if receipts are later anchored.
Architecture

The core design is privacy-preserving by default.

1

Tenant-scoped action for better privacy boundaries

2

Decision-bound signal hash for case-specific proof binding

3

HMAC nullifier digest for duplicate checks without raw nullifier storage

4

Receipt hashes today, World Chain anchoring later
