Consent Receipts

I have read about Consent Receipts in the Sovrin document https://www.evernym.com/wp-content/uploads/2017/07/How-Sovrin-Works.pdf. I wanted to check if this has been implemented in any of the indy code yet and If not is it on the roadmap? Are there any examples of how this would work?

You should start with the Aries RFC on this topic:

Evernym has some customers working on consent receipt use cases, but I don’t see any public information on how they are doing it.

The Indy Semantics Working Group regularly discusses this topic. See #indy-semantics on http://chat.hyperledger.org
