This is the artificially colorized version of a historical picture of an unemployed American worker during the Great Depression showing his social security number tattooed to his arm.

More details about the picture here.

The first thing that came to my head when I saw this was Bitcoin, our own modern version of something we cannot forget. I’m talking about the seed phrase that allows one to make Bitcoin transactions from their wallet.

There must be somebody in the world who has tattooed their seed phrases somewhere in their body. I’m not sure they’d have asked a tattoo artist to do it. That would expose the seed and consequently defeat the purpose.

Even if you decide to do it yourself Memento style, there would be a risk of exposure during vacations on the beach/pool side or in moments of intimacy.

Maybe the ultimate solution would be to tattoo a poem containing the seed words in a sequence only known to yourself.

Just don’t forget the sequencing algorithm.

Well, that will be a topic for another post.
