Lucre coins are blinded, which means that the mint does not
know what coin it just issued, and cannot relate the new coin
to the old, thus cannot discover that Bob has been paid by
Carol.
When the mint issues a coin to Bob, it employs a public
blinding factor supplied by Bob. Bob then applies a secret
deblinding factor, to reveal the real coin, which the mint
cannot recognize as the one it issued.
