Every Bitcoin Nova transaction, by default, obfuscates sending and receiving addresses as well as transacted amounts. This always-on privacy means that every Bitcoin Nova user's activity enhances the privacy of all other users, unlike selectively transparent cryptocurrencies (e.g. Z-Cash).
Bitcoin Nova is fungible. By virtue of obfuscation, Bitcoin Nova can not become tainted through participation in previous transactions. This means Bitcoin Nova will always be accepted without the risk of censorship.
