One last idea. Sorry to spam the thread. I think Boolberry is the best so far, because it stands out from the 100s of coins. If you are going to pick something new, it really needs to be weird enough to stand out. But not so weird that it doesn't improve upon Boolberry. You need a noun, so ciphering doesn't qualify in its traditional definition. Boolberry can appeal to the normal people very much. Even they don't know what Bool means, they know blueberries and blackberry. They won't know what it is, but curiosity killed the cat. As you can see, boolberry has grown on us and we started to like it. So that means it is brandable.

iono.org is available

Problem is people might think oh no instead of ion, ionosphere, and i dunno.

dunno is another idea, but it isn't normally a noun. A name that states the anonymity is usually negative. I also thought of alibi, hoodini, sleight, etc..

Edit: also pixie
