Hi,

I hope you won't mind me asking this question but I couldn't find any info about it online.

Basically memorizing long onion address is inhumane so people rely on vanity address + copy pasting it somewhere, both being security issues but understandable practical compromise.

So why not using things like bitcoin's BIP39 (example link) to turn those long random strings into human readable forms? Anyone can memorize a list of 50 words with enough time and technique.

Is it because of a loss of entropy? Would the list of words be too long like 500 words? I'd be surprised given it's heavily used in cryptocurrencies and nobody's stealing money by guessing seeds.

I'm sure the people behind the tor project have thought about this already and are super smart but I was interested in the reasons :)

Have a nice day!
