プレゼンテーション・グラフ
An example verifiable presentation presented schematically. There are two major components:
A verifiable presentation, and its proof.
The presentation consists of some metadata (here, terms of use),
and a verifiable credential with its proof.
The credential also has metadata, including a date of issue and an issuer, and a claim,
in this case that "Pat" is an alumnus of "Example University"
(which is also the issuer of the credential).
The proof of the credential and the proof of the presentation have similar structure:
A signature with a nonce, date, algorithm used, and a public key for the proof's creator.
