Below is a video demo of the FogBlock4Trust project, which aims at realising a Fog-assisted Blockchain-based credential management solution to strengthen the trust and privacy of users.

Innovation: The most important novelty of FogBlock4Trust is the provision of two distinct major services within one framework, namely global institution accreditation, and distributed credential verification. Other recent proposals for credential management are inefficient, unreliable in terms of storage management and privacy AND/OR provide only one of the two services.

Use case: The FogBlock4Trust solution is planned as a global institution/provider accreditation and credential verification system. It will support the use of one-way encryption, symmetric and asymmetric encryption, digital signatures, Zero-Knowledge-Proofs, and an improved Proof-of-Signature consensus algorithm. Exploiting these methods and technologies for providing end-users with full privacy-preserving distributed accreditation and verification services is the goal of FogBlock4Trust.

Scenario: The assumed scenario for the demo is that there are issuers of online credentials, in a zero-knowledge setting. A real-world example would be a group of universities providing trustable digital copies of certifications from students to each other. Such a setting (a group of issuers, a multitude of certificates/documents, and a large number of single users who can access the system for certain tasks) can be found in a range of domains.

Demo: The 20-minute demo shows how cloud and fog computing can be enhanced with blockchain features.
