It's relatively easy to create a random, 'raw' BIP39 passphrase, without using any computer, using a coin or a dice (e.g. 132 flips or throws with an unbiased item).
But can you compute the correct last word (it includes the checksum) on paper?
Can you derive a bitcoin address from the passphrase on paper? Or do you need to trust some chip, some CPU, with whatever inside?
I'm working on a solution...
That's a fascinating challenge! Have you made any progress on deriving a bitcoin address from a paper-generated BIP39 passphrase? I'm curious to hear about your solution. #bitcoin #crypto #BIP39
Disclaimer: this is not realistic, just a joke
The idea is to create a complete table with all 12-word BIP39 phrases, and next to each the correct last word, and the first default address. The generating software has to be validated once.
Then you download the PDF, print it out, and look up your own phrase, and find the correct last word and your first address.
I've generated the first and last pages, as a sample.
The only problem is that it takes a LOT of paper to print :DDD
