I see that that was indeed considered what we call paper today, unlike
the ancient Egyptian papyrus.

Some sheets
Since paper as we know it today doesn't even exist so long that can't
be true. Maybe you are pointing to the few surviving papyrus texts?
Most have not survived.
I've personally seen paper ballots from elections in the Senate of
ancient Rome. Admittedly, this was 15 years ago so I can no

Sorry for the lame tracking links; that's apparently a setting
automatically enabled by SendGrid which I'm using to send out on my custom
email domain. Hopefully they're disabled now and below are showing the
original URLs as I had pasted them, else I give up, lol.

The EEPROM notes are intriguing to me, and if that's an option you're
considering, I went ahead and tossed up some old code onto a gist if you're
interested. It's a crude example of storing PGP private key in flash (vs.
SRAM) using a little PROGMEM hack for the Arduino Uno:

So I guess all that leaves us with at this point is laser welded
inscriptions onto a block of metal, installed backwards as the cornerstone
of the next monument being preserved by a historic society.
It’ll be the next iteration of 3D printing: MIaaB (Metal Inscriptions as a
Backup).

Paper tape had a high error rate (& tear rate). It chaffed & built
dirt on reader, & absorbed finger grease & misread whether optical
or capacitive readers. Mylar (plastic) was better,
I think, paper tapes as in the years 70 would be the best media for this

Thank you for sharing this Francesco.
Yes, having a secure, durable offline backup is important.
Coming from the Bitcoin space, we've already explored many options in an
effort to allow users easily to back up private keys.
I have to say the effort involved in your method seems unrealistic for

I decided to back up my secret gpg key with pencil and paper,
