Explainer video Energy Loan

This video explains how the city of Gent (Belgium) and Howest University realized a proof of concept for a blockchain-enabled solution that makes applying for energy support easier, quicker, and more efficient.

Using Self Sovereign Identity

The Energy Loan proof of concept is built upon the concept of ‘self-sovereign identity’ that is enabled by a blockchain solution. The interaction between users/citizens and organizations is managed via an identity wallet, which stores verifiable credentials for the users.

Citizens choose which wallet provider they wish to use. The credentials are issued by organisations via trusted issuer registries, so that the credentials can be cryptographically verified. No personal data is stored on the blockchain, but the blockchain solution enables an individual’s credentials to be verified in a privacy-friendly way.

The pilot is using the European Blockchain Services Infrastructure (EBSI), in which the decentralised identifiers (DIDs) of the issuers are stored on a blockchain. They are listed in a Trusted Registry, so that verifiers can verify the signature on the Verifiable Credentials of the citizens.
