SAHEL SSI Architecture and Token

The SAHEL SSI architecture is a modular trust framework that enables the issuance, holding, and verification of digital credentials without centralizing personal data or controlling user identity.

User sovereignty by design

Identity data and credentials always remain under the control of the holder.

Explicit and auditable trust governance

Issuer authorization and credential rules are transparent, verifiable, and time-bound.

Privacy-preserving verification

Credentials can be verified without centralized databases or user tracking.

Responsible use of blockchain

Blockchain is used only to anchor governance and integrity, never to manage identity or users
