The world’s most advanced paper backup hardware device is at your fingertips

[@nihalatwal]

This is the most marvelous RasPi project I've seen. Thanks a lot for putting in the effort. I hope this project becomes popular and more people adopt it, or even adapt the idea for other devices :)

[@sunknudsen]

Thanks for the kind words Nihal!

Consider beginning w/ 'Use Case' as not academic. In the growing realization financial decentralization is inevitable, ponder the demographic. Great content!! Go go go

[@0xGramajo]

Awesome content as always. Donated because you deserve all this. Hopefully one day we get that coldcard episode, been loving that product.

[@sunknudsen]

Thanks for the push Juan! Coinkite got in touch and should send over a few devices for review. The episode will likely not make it into the Bitcoin series but I am looking forward to publishing shortly.

[@liafdrah3920]

Bro, you are incredible…This video sparked some amazing ideas in me and I can’t thank you enough for what you are doing

[@edrumsense]

Just... AWESOME! watching this from My Raspi4 I am waiting for this video since the first time you announced it "Damn it Sun!" :-) thanks!

[@sunknudsen]

Pleasure! Happy the episode (and research) is finally out.

You are such a nerd! I love it!

Great project! Kudos!

why are the signed releases on the video have been removed from the reference material

[@archetypaltrader6166]

I have begun this project and was wondering what happened to the signed release section in the reference material, seems like they have been removed. with limited tech experience I think you could do a a series on this project alone. Really focus on each step to help people build out this project. I've rewatched a dozen times and is still hard to grasp

[@sateshmahadeo4366]

I want to make something like this with a RPi 2. It has no wireless hardware, so it is great for airgapped applications. It has a 900 MHz cpu and 1 GB of ram. What do you think of this?

[@dannyspencer1719]

Hey Sun, Love the content, any way the sweatshirts will be up for sale again? Thanks

[@sunknudsen]

Hey Danny, thanks for the push and for your enthusiasm towards DO NOT TRACK sweatshirts. I might put together limited runs that I would fulfill without using third parties (except Stripe in the context of credit card payments). It would be a labour of love for the privacy guides community with no intention to earn revenue, just break-even. Btw, are others reading this comment interested? Price point would be around 40 USD plus shipping.

[@dannyspencer1719]

@@sunknudsen I'm in whenever you do a run, thanks!

[@sl0229]

Hey Sun. Great content as always! I'm only interested in creating encrypted qr codes with the raspberry Pi. Can I then skip a few steps (e.g. 8, 9 and 10)?

[@sunknudsen]

Hey, if you only want to create encrypted paper backups of strings you type in without having the device verify integrity of BIP39 mnemonics, I believe you can skip steps 5 (if using HDMI display), 7 (if you don’t need Shamir Secret Sharing), 8, 9, 11, 12, 13, 18 and 19.

[@bmw525service]

Hi Sun you mentioned in a previous video using a waterproof paper for the QR code print outs. What are you using for print your QR codes on.

[@sunknudsen]

Hey David, the paper backups shown on the episodes were printed using a SELPHY CP1300 printer. The paper has a plastic finish that is water resistant. IMPORTANT DISCLAIMER: one has to destroy the cartridge after printing sensitive images because it may contain a negative of what has been printed. For increased waterproofing, I store hardware wallet and paper backup pairs in aLOKSAK driving-certified bags.

[@BenWeeks-ca]

Yupo paper should work if you can find a version that can be printed on. It's synthetic.

[@mad-c4o]

Hi, Sun! I was thinking why can’t we use any modern smartphone as air-gapped device for crypto anything. I mean now with secret seed you can restore your wallet on the disconnected from any network smartphone, do your things and erase the device (or not). It’s much cheaper than hardware wallets and easier than DIYing Raspberry Pi. And this solution seems like secure as others. Even more secure due simplicity for average user. Also smartphones easy to destroy in case of emergency, also it doesn’t bring any attention as hardware wallets, good encryption by default (on iPhones). What do you think?

[@ghittons9350]

Hi Sun, is it possible to adapt this project for an old pc, I explain better, I have an old pc to which I removed the wifi card and bluetooth and I installed Linux, and I would like to know if it were possible to replicate this fantastic project even there, thanks in advance.

[@sunknudsen]

Hey, I don’t see why not. It would require some work as a few steps are Raspberry Pi-specific. That said, Raspberry Pi OS is based on Debian (and uses APT) so I would start there.

[@edrovfazzcarz1355]

Hi Sun, awesome video ( again), kind of dumb question sorry, I can see you use a trezor, I have Ledger is the concept with the Pi compatible with Ledger?

[@sunknudsen]

Thanks for kind words… so far, project only support Trezor hardware (with very limited COLDCARD support).

[@Boehmroth]

Can anyone tell me, if that project is still available? Or is it maybe replaced by Superbacked?

[@sunknudsen]

Hey! Reference material for this project is still available on GitHub. That said, Superbacked is its successor.

[@ricmagx]

Could we replicate this on Tails? For us "no raspberry Py" users

[@sunknudsen]

Hey Ricardo, unfortunately, I do not believe it is possible without significant patches. My gut feeling is it wouldn’t be as secure either given objective is to develop an amnesic operating system that is also no able to connect to the Internet. The Raspberry Pi hardware is very suited to this kind of project.

[@ricmagx]

@@sunknudsen Thank you, One last question. In ten years if my family does not have the RP, how would it be able to access the keys? What kind of instructions? Sorry to much of a question, maybe a next video...

[@jeanmichelsarr6040]

What is the difference with a paper wallet ?

[@sunknudsen]

Not sure I understand your question, but generated paper backups are encrypted adding an extra layer of privacy and security (among other features).

[@damiansetunge8463]

Bruh you just made all my security units at uni wayy more cooler

[@CanesFan65]

WAY TOO COMPLICATED for the average person. Maybe great for someone YOUNG and ambitious but not for us old folks. Until this stuff becomes much easier to understand most people will not be willing to do this. After all - NOT EVERYONE has the technical knowledge and some of us who do have technical day jobs and would rather RELAX after work than deal with all the effort involved in doing this. I bought a raspberry pi3+ a couple years ago and now it sits in the closet doing nothing. There actually DOES come a point in time where you DO NOT want to have to keep LEARNING SOMETHING NEW - especially TECHNICAL Stuff.

[@sunknudsen]

Feel you… I am pretty much there as well. That said, when one has time, this stuff is fascinating!

Interesting… thanks for sharing this valuable feedback. Trying to be as authentic as possible and I tend to use that word in real life. That said, this content should be watchable in an academic context. Will give this one some thought.
