We definitely need a naming protocol as much as we need a privacy protocol! I agree that Lelantus is a great brand to focus on, it has heralded a new era for the FIRO privacy project. The name changes for the privacy protocol should be reserved for when there is a major change in the code. It is a major flag to people that something has changed. If we changed the name every time a hard-fork occurred the project would be very hard to follow.
How about if we use some of the really cool names that people have come up with above along with Lelantus to create a double barrelled name e.g. Lelantus-Firebird ? Offering names is fun and encourages community engagement. The idea of limiting names to mythical creatures / gods is not a bad one. The superpower of the supernatural being in question can then be related to the new upgrade to the protocol e.g. Lelantus Breksta - (Lithuanian goddess of dusk and dreams) because protecting users identities between burning and redeeming coins is like protecting dreams between dusk and dawn.
I really like the idea of skipping Lelantus v2 and moving straight on to NPP, let’s not make work for the dev team. Only moon boys want to see things moving quickly; to pump the price. FIRO is the best crypto-privacy project of the lot because it is research driven and has a strong set of guiding values. The focus needs to be on increasing the practicable level of privacy and avoiding the threat of censorship. From Reuben’s write-up it appears that NPP, and not Lelantus v2, takes the protocol in the right direction for further improvements to these ends.
