How? You wrap your gift three times according to the Crypto Santa instructions. Each layer of wrapping has the name of someone at your party.
Onion Routing is the technique used by Tor, a system for browsing the web anonymously, however, instead of data, Crypto Santa anonymizes the exchange of real gifts at your holiday party.
