In the 9th NFT Guild Roundtable, held on October 5, 2022, we continued the NFT Verification standard discussion.

Our dilemma is this: we have a need to prove ownership of a token policy. As deliberated previously, the owner pubkey hash is visible in regular token scripts, so we discussed using this proof.

After thought and exploration, however, we see that this is not available in minting policy scripts (smart contracts). We are therefore back at the start.

How can we prove policy ownership for both types of policies?
