Years ago I started a collection of convolution optimization resources: https://github.com/mratsim/laser/wiki/Convolution-optimisati...
Also checked and apparently Nvidia Cutlass now supports generic convolutions: https://github.com/NVIDIA/cutlass

At a glance it seems fair to say that this is both a cryptocurrency library and a cryptography library.
The only truly general purpose thing here is SHA256. Every protocol on its supported list starts with either "ethereum" or "evm", and to the best of my knowledge the other primitives have seen very little use besides cryptocurrency.
The Internet Engineering Task Force, which in particular standardizes TLS, has acknowledge my contributions for my contributions to the very generic and globally useful hashing-to-curve primitive: https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-hash-t...
And BLS signatures are standards as well: https://www.ietf.org/archive/id/draft-irtf-cfrg-bls-signatur...

BLS signatures are general purpose, the only Ethereum specific thing is choosing which elliptic curves are used for public keys and which for signatures as well as a prefix before hashing inputs.
Similarly KZG polynomial commitments are generic, the Ethereum specific thing is the trusted setup ceremony which needs to be specialized per protocol.
The finite field backends and the elliptic curves supported are all generic as well: https://github.com/mratsim/constantine/blob/master/constanti...
I think this is cool, but how sure are the authors that this is side-channel safe? There is a similar (modular, high performance, zero-dependency) library in Common Lisp but it can't give side-channel guarantees due to how some Common Lisp compilers implement integer and arithmetic functions
Great question, first of all I did extensive research https://github.com/mratsim/constantine/wiki/Constant-time-ar....
Then the library defines its own types SecretBool and SecretWord throughough library that cannot be mixed with regular Nim types and are based on uint32/uint64 so the compiler cannot assume 0/1 and do boolean logic.
Assembly is used to avoid compilers getting too smart and reintroducing branches but the no-assembly fallback should still compile without branches.
By convention, all variable-time cryptographic functions are suffixed _vartime.
There is a plan to add automated constant-time checks as well https://github.com/mratsim/constantine/issues/7.

The EU claims their law applies globally regardless of if people set foot in or do business in the EU. According to the EU, an EU citizen just needs to visit a site and the law applies, regardless of where the site is hosted.
According to the EU, the GDPR applies to some small shop owner in China with a website that harvests all data it can that isn't advertising in the EU, courting EU citizens in any way, has no business with the EU, etc.
According to the US, an US citizen just have to open a bank account anywhere in the world and the law applies, regardless of where the bank is hosted.

Funnily enough, there actually was the Phoebus cartel [1] which sought to reduce the lifespan of incandescent light bulbs to around 1,000 hours and raise prices.
Reminded me of Bastiat's candlestick maker's petition:

That situation is quite different. The US is using its significant power and weight to coerce those non-US banks into compliance with FACTA. Those banks don't have to comply, but they want to do business with the US and US companies, then they don't have much of a choice.
It's not like they just made a law and now insisted it applies globally, which is what the EU did.
Why is it different?
People don't have to comply to GDPR but if they want to serve EU folks then they don't have a choice.

I've never worked with a project with more than 7 dimensions, yet
What would be the 7 dimensions?
At that point it was easier to do it myself.
