Re: Authorized Issuer Lists

Eduardo, you are correct that the GLEIF vLEI ecosystem
<https://www.gleif.org/en/vlei/introducing-the-verifiable-lei-vlei>
primarily relies on chained VCs instead of trust registries. However GLEIF
will also maintain a registry of qualified vLEI issuers (QVIs). Whether or
not the GLEIF registry will support a standard trust registry protocol such
as the ToIP Trust Registry Protocol Specification is TBD.

It is also worth noting that due to the chaining and some other
requirements, GLEIF vLEIs are not currently compatible with the Verifiable
Credentials Data Model 1.0 spec. They use a different spec called Authentic
Chained Data Container
<https://trustoverip.github.io/tswg-acdc-specification/draft-ssmith-acdc.html>
(ACDC) that is being submitted to IETF. However the lead author, Sam Smith,
is participating as an invited expert in the new W3C Verifiable Credentials
2.0 Working Group in the hopes that ACDC can become a W3C compatible format.
