Re: Performance question for JSON-LD with vc.js

Dmitri – that also forces all contexts to be (a) accessible and (b) machine readable…neither of which a mandatory requirement of either JSON-LD or VC itself.

Hi Anil,

> When using vc.js, I have observed that if the pre-configured contexts are not loaded, I am unable to even sign/verify the credential. I might have to come up with our own processing code to circumvent this issue.

For security reasons, the vc-js library /does not/ allow loading of arbitrary contexts from the web. You have to explicitly allow-list them, by providing a document loader function tailored to your usecase.
