AFAIU, a PubKeyHash is the hash of a public key, which a public address is derived from.
When I have a policy like this …
I wonder what level of security that would provide. For example, is it possible for an adversary who knows a plausible set of public addresses to derive a set of corresponding PubKeyHash? Would it therefore be possible for this adversary to mint tokens based on the PubKeyHash? I guess not, because mkPolicy requires the minting Tx to be signed by the owner of the PubKeyHash.
In Cardano, how does a PubKeyHash relate to an ADA address?
