A proof is UNSPENT if it has not been spent yet
A proof is PENDING if it is being processed in a transaction (in an ongoing payment). A PENDING proof cannot be used in another transaction until it is live again.
A proof is SPENT if it has been redeemed and its secret is in the list of spent secrets of the mint.
