Petros Kavassalis: How should a Disposable Identity work? Technically speaking it is made of 2 parts
1. A back-end which gathers a set of Verifiable Credentials (some of them are referred to official identities obtained from authoritative sources) -- these data are stored in the Owner’s mobile wallet.
2. A front-end, which is the mechanism of Verifiable Presentation that creates an actual proof of identity which can be instantly verified (that is to say, the authorship of identity data packaging is verifiable). The “attribute linking” can’t be made by the Service; only the Identity Owner can create and present links between the different Disposable Identities he/she owns, and annex them to an official identity credential.
