Decentralized Identity & Reputation

Self-sovereign identity, verifiable credentials and reputation that resists manipulation.

Identity on open networks must be portable, private and hard to forge. We study decentralized identifiers, verifiable academic credentials and soulbound tokens.

On the reputation side, we model how trust evolves from evidence over time and how reputation can safely weight consensus or peer review.
