Status of specs and implementations

Hello CCG community! :)

I am Cosma and I have been following the VC developments over the last few
weeks. As of now, I found many specifications covering different aspects
and layers of the SSI infrastructure, but I found it difficult to fully
understand the commonalities and differences.

There have been previous cross-community works such as this:
https://github.com/decentralized-identity/decentralized-identity.github.io/blob/master/assets/crosscommunity-architecture-survey-oct-2020.pdf

Although there have been several changes, I couldn't find anything newer
than the above chart (Oct 2020). I think that having an updated version
would help newcomers (like me) see the big picture and find their way to
contributing more easily (I am doing my Computer Engineering MSc thesis).

Do you know if there is a current version or WIP of the said overview?

Regards,
Cosma
