Questions about DIDs and Identity Credentials

Hi there,

First of all a lot of thanks for writing the specifications. The followings
are my questions about DIDs and Identity Credentials.

1. What is the difference or relationship between Identity Credentials [1],
Verifiable Credentials [2], and Verifiable Claims [3]? I haven't read all
the specifications thoroughly yet but they all seem to deal with the same
thing.

2. Is the Credential defined in 2. Terminology of the Identity Credentials
specification the same with one in the context of Credential Management
Level 1 [4]? If so and everything goes well, I can store my digital
passport in the form of Credential defined in the terminology in my mobile
browser through navigator.credentials.store using some Identity Provider,
and use it to identify myself in other countries. Also, I can manage my
credentials on my browser without installing 3rd party app. Does it make
sense?

3. Needless to say, DIDs and Identity Credentials match perfectly with
blockchain environment. Is there any blockchain project that makes good use
of them?

Thanks,
