Re: Clarifications between EUDI wallet and EBSI

Hi Nikos,

ARF needs to be generic =>  Please note that ARF clarifies that the term "certificate" does not mean only X.509 certificates, but it includes also other formats of certificates, such as in Distributed Ledgers” => so DIDs are covered

Indeed, EBSI and EUDI wallet are completely separated. EUDI ARF does not mention DIDs at all and I believe this is on purpose.

Best,
