Haha, didn't know it was german, it's often used in polandball comics and it sounds funny in an english phrase.

Anyway I'm keeping a list of all anonymization techniques (here, if you're curious) I'll definitely add navajo (for the time being I added it to my portfolio ).

Could you confirm/deny a few points? (stuff I didn't understand from the whitepaper):
1) the navajo anonymization uses no masternode-like feature, NMG and CSG are actually just run by regular nodes
2) the transaction follows some sort of onion routing so no node beside the sender could possibly link transaction to sender ip unless they work in tandem with other malicious nodes nor run some sort of network analysis.
3)I'm assuming transactions are more or less the same size so it's not possible to distinguish transactions happening at the same time, but there are no artificial delays/salting/padding used specifically to avoid linking network activity to transfers
4) the address of the sender does not appear in the blockchain and it disappear from the network (subchains included) once the transaction is completed but what happens if the NMG or CSG or any other node involved tries to keep knowledge of the transaction or the issuer? And what happens if a malicious NMG CSG pair tries to make coins appear?
5) well this is gossip, but, did you contact the Navajos in the end?

Personally I see navajo sending  technique to be as interesting as bitcoindark teleport, where teleport can evade any network/activity analysis and navajo makes blockchain analysis pointless. I suppose teleport protocol could be built on top of navajo for paranoia level security, that's be interesting to see .
BTW, is there any plan to join supernet, blocknet or the likes?
