Years later we put a newer version of this chip with a secure element into Bitcoin bills.[1]
Hand waiving a lot of the details, each note basically becomes a hardware wallet with some additional features to prevent double spending.

- garbthetill 1y agoThis is cool, I thought of something similar, didnt know someone implemented it and the swizz like bank note design is neat. but its still has flaws imo and just makes it a novelty rather than something practical or useful, for example unless the vendor has change, you would have to spend your btc cash denomination as a whole or exchange it for fiat. what if both the vendor & customer didn't have internet access, how would they check if the cash hasn't been used? idk if you can write back to an rfid that may solve some problems
- jama211 1y agoWith respect, this gives me serious ick. Black mirror vibes.
- va1a 1y agoIt's a hardware wallet that just looks cool. Where's the "black mirror vibes". There's not much nefarious tech here.
- jama211 1y agolooks at the crypto community and gestures broadly
- akimbostrawman 1y agoThe ick and black mirror vibes comes from the technical fact that bitcoin is non fungible and publicly traceable by design making it a surveillance states dream. Luckily there are superior alt coins that don't have that flaw.
- jama211 1y agoErr, actually the ick factor for me was the crypto bro mentality and the general seedy nature of the state of crypto and those who use it.

- akimbostrawman 1y agoTurns out if you only look at people trying to turn a profit you will find bad people. It's like complaining about investment being seedy because you only watch wallstreetbets. That should be the point where the intellectual curious hacker should try to broaden there horizon beyond the superficial surface. I don't see the seedy nature you try to apply to a whole industry if anything i experience the opposite.

- Nextgrid 1y agoAre you involved in the project? I assume this is essentially a paper-thin HSM/Yubikey, right? Is there any way I can use these as general-purpose HSMs outside of bitcoin/cryptocurrency contexts? Just as a novelty. Let's say I just want to store a private key on it and use it for SSH/etc authentication - would that be possible?
