Show HN: Wagyu – Rust library for generating cryptocurrency wallets

Yes, that would be better!

However, they seem to be using `XorShiftRng` in their tests, which is no cryptographically secure, so they can't use `CryptoRng` over `Rng` in their API without resorting to compile-time magic. I think they should just use `StdRng`, which is cryptographically secure and quite fast.

Spot on. I recently cooked a piece of wagyu and you just cannot ignore the marbling.

Also irrelevant I know.

When you are writing software that you just _know_ is going to be used to store and manage money as its primary purpose, that means there are direct monetary benefits to people who can find exploits in your software: it isn't "maybe some government wants this" but "with an exploit I can directly steal a hundred million dollars and I would likely be unable to be caught". That makes you paranoid about getting the security correct.

I can’t find the posts now, but MaidSafe switched over after their CEO gave Rust a try and was extremely impressed; this was back in 2014? You might want to dig into that, they explained their reasons at the time.

WebAssembly has also been on an upward trajectory in this space, and so there’s some synergy there too.

I think it's probably something along the lines of:

* Rust meets basic constraints (performance, reliability)

* A few early movers chose rust, and they likely share information and libraries, so it makes sense to just go in on it

Given that cryptocurrency is a fairly young space, having everyone leveraging the same tooling probably increases productivity. One day someone might say "We can get more productive if we leverage Language X, let's invest there", but until then everyone else is probably thinking "Oh, the libraries I need are in Rust, guess I'll use Rust".

I agree, wagyu beef is typically more expensive and richer in flavour than regular beef. The lightweight analogy doesn't really match that... Maybe there's another reason for the name

Lightweight in software is a weird adjective. I used to assume it meant light on resources but after seeing what passes for "lightweight" I've disabused myself of that notion. Instead, I've seen it mean any of the following:

not-much-ceremony-to-use (e.g. https://github.com/emilk/loguru)

small amount of code but huge number of dependencies (e.g. micromodal https://github.com/ghosh/Micromodal/blob/master/yarn.lock )

But the common denominator appears to mean "feature incomplete".

There's no actual market for that. In theory, if people were using cryptocurrency to buy stuff and they believed in the "be your own bank" philosophy there would be a market, but none of that really exists.

lol
