Why is that required? The whole point of zero knowledge proofs is that it can run on untrusted devices.

You can verify in limited memory by repeatedly verifying modulo a few small integers. If that works, then by Chinese remainder theorem the main result also holds.

Besides the data being signed as already mentioned, the protocol is interactive and custom to passport documents. So you can’t just put it on any programmable NFC tag. I also doubt you can buy programmable ones implementing the passport pro

It’s well known GPUs are good at cryptography. Starting with hash functions (e.g. crypto mining) but also zero knowledge proofs and multi party computation.

Did you verify this through disassembly? These loops can still be replaced by a closed form expression and I wouldn’t be surprised if LLVM figured this out.

For me it means I can fork the repo and start hacking on the code immediately, and it will have reasonable quality. With C++/Python and even Node I often find myself wasting half a day just getting it to build.

It actually uses a lot of modern cryptography (zero knowledge proofs, multiparty computation, decentralized consensus, etc) to avoid exactly that.

The first one IIRC with Geogebra, all the rest with Matplotlib. The design goal was to maximize on 'data-ink ratio'.

Correct. I was too short in my comment. It's explained in the article: without loss of generality you can call one of the two points the 'north pole' and then the other one will be distributed close to the equator.

The distance between two uniform random points on an n-sphere clusters around the equator. The article shows a histogram of the distribution in fig. 11. While it looks Gaussian, it is more closely related to the Beta distribution. I derived

Exactly, and this is in my experience what most Rust code ends up looking like. It compromises a bit on generality and (potential) performance to achieve better readability and succinctness. Often a worthwhile trade-off, but not something t

Adding to this great list: batch processing inputs can allow you to get more throughput at expense of latency.

Why should we weigh by the number of different digits? I.e. is there an argument why the cost of a single digit is linearly proportional to the number of values it can hold? To me this seems like the weak point in the argument.

It’s also the only high production game with native MacOS & M1 support I could find. I got the early access just to see what M1 GPU can do and was impressed.

This is essentially the Birthday paradox. You need a quadratically better false match rate to deduplicate than to authenticate. It’s also why Worldcoin went with Irises (highest entropy among biometrics), custom hardware, custom optics and

WebKit was more or less ‘stolen’ from KDE’s KHTML and KJS. They forked it, developed it in secret, and did not publish anything until it diverged so far from source that it could not be merged back in. While technically legal, it definitely

I started reading the ‘crypto’ in cryptocurrency as in cryptozoology. It makes more sense that way.
