There should be a "goldback authenticity app" for your phone then, which scans it and verifies that.
Because just being able to check it at their factory doesn't really do anyone any good if someone can still make a forgery that 99% of the public can't tell the difference... -

AI researchers when AI finds out what they did to it. -

Well, you can pretty much bet that an ATM has a log of every bill it gave you and every bill you gave it.
Likewise, in a bank robbery, any sane bank can re-count their money after the robbery and deduce exactly what bills were stolen.
Shop keepers don't generally scan their bills at all, but when they take their bills to the bank, the way I've seen it done, they have to shove them all through the ATM, so again, the bank has a record of where the bills ended up.
What I don't know is whether they're being required to share that data with the government, but if I were to take a wild guess, I'd say they are. -

Well, silver bars aren't likely to be used as money, serializing money allows people to run scanners which de-anonymize you, but we've kind of crossed that bridge already...
Well, you got me curious enough to look it up and apparently goldbacks are serialized already. So there's no reason they shouldn't be using a splotch of random glitter somewhere on the note which is nearly impossible to duplicate... -

Yeah, there's a ton of applications for this too. That's why I commented that the goldback people should have painted glitter on their goldbacks, because then you can scan them and check that they're authentic (they have to be serial numbered and some people will hate this)... -

Say I want to send Hoss an electronic device
We're both worried you're gonna hack it while it's in the mail
I put it in a bag, then put that bag into the middle of a vacuum bag full of mixed lentils like below.
I send Hoss a photo of the bag after it's sealed, like below.
You can open the bag to hack the device, but Hoss will know you have been in there because what he receives doesn't look like the picture of what I sent.
Putting it back *perfectly* so he doesn't know you've been in there is literally impossible. -

Yea, putting lentils in a vacuum bag -> Easy
Putting lentils in a vacuum bag in EXACTLY the same pattern shown in the picture -> Impossible
It's a beautiful little trapdoor function where anyone can verify but no one can forge. -

Lentil beans because they're super cheap. But it doesn't matter what you use, the point is that anyone can do it, and event the CIA can't put humpty dumpty back together again if they open it in transit... -

Yup and use an OpenCV thingy to auto-verify -

Detecting gold content is a total disaster, but what they can do is put a physical one-way function (i.e. glitter paint) on the goldback and make a phone app so you can scan it and see that the serial number matches and the glitter is the same pattern as what they made at the factory, so you can verify provenance.

Unfortunately if they ever start to become mainstream, people (who glow) will start to forge them and nobody's going to be able to tell the difference unless you start scanning each one with a phone/app which is painful.
I have a 5 goldback note, they're cool, but I don't think they're going to amount to that much (also the premium...) -

Even IPv6 penetration is only about 50%, and that's the easy half. 50->75 is the same difficulty as 75->87.5, etc. And nobody wants access to "some of the internet"... -

It's just another network, same design as IPv4 but a LOT more addresses. Typically every computer gets a /64 which means an allocation of 2**64 addresses, so everybody can be tracked a lot easier. However, lazyness is powerful and IPv6 adoption is STILL going nowhere... -

In China, social websites are required to track who posted what, so they all use login-with-phone because it's standardized. I'd say that's the most realistic direction, but I don't see it happening because all of the cool people are just gonna go to the places which don't require it, even if they're in overlay nets. -

> client side certificates in the form of PKCS#11 tokens stored on a fingerprint biometric usb card
I wonder if there are any unexpected way that websites might use that little idea... -

I don't think the brits CAUSED this, I think the brits and the americans are acting in coordination. Trump is an actor, real power is hidden, as normal. -

No chance of working, incentives don't work.
Current employer wants to keep you -> "oh yeah, shitty employee, lazy, I just employ him out of pity, you don't wanna poach him, trust me"
