Add makefile to create identities and issue/receive claim #11

Closed nedgar closed 1 year ago

nedgar commented 1 year ago

Adds a Makefile to:

create the identities for JohnDoe and AliceWonder
issue the claim (issued by JohnDoe for AliceWonder)
receive the claim (copy the claim file from JohnDoe/claims to AliceWonder/received-claims)

One related Q: should we rename received-claims to just claims, so that verification can be done against directly issued claims, not just received claims?

FYI @jimthematrix @Chengxuan

I changed the claim-related targets to be less declarative (more imperative) so they can be run again as needed, and more easily interleaved with other steps e.g. publishing on-chain.

Example usage:

make clean identities
publish JohnDoe's state to blockchain (per README)
make issue-claim
re-publish JohnDoe's state to blockchain
make receive-claim
launch the verifier UI; download claim QR code to ~/Downloads/challenge-qr.png
make respond-to-challenge
generate the ZK proof

Suggestion: The makefile uses jq to extract the public ID for a given a name, to avoid hardcoding IDs into the makefile. This could be simplified if the claim subcommand supported a --holder-name arg (in addition to --holder).

Edit: nm, this would simplify the claim command a bit, but wouldn't help beyond that given the use of IDs in the claim filenames.
