vanitygen-plusplus VS nix-autobahn

I am using vanitygen++: https://github.com/10gic/vanitygen-plusplus

One could easily hack the bitcrack code for beckh32 but checkout vanitygen use -Z to specify the known part of the key https://github.com/10gic/vanitygen-plusplus I’m fairly sure it can do bech32 out of the box

I run NixOS, but I'm relatively new to Nix. A couple weeks ago I was trying to get an old vanity key generator to build because it wasn't on nixpkgs (vanitygen++) and on a lark I decided to write my own derivation using some examples of similar C++ packages I found and figuring out what nix packages it needed to build. So I did, and the maintainer accepted the PR: https://github.com/10gic/vanitygen-plusplus/commit/7bcee06f3... Note that I am not a C++ developer and only know the basics about how to get C/C++ things to build.

So what does this get us? In theory, this is now trivially-buildable on any distro that has nix installed, or on nixos. I haven't converted it to a flake yet (still learning that) but if I (or someone else) did, it would be deterministically reproducible anywhere on nix.

I agree that there's a learning curve on figuring out the "recipe" for a thing, but once someone does that work, it's basically done forever. Which is a promise that no other system can even approach.

And once you figure out a certain amount of it, this moment will come where you realize you want every system you deal with to be Nixified. Like the guy elsewhere in this thread who rebuilt his own router using NixOS and loves it.

Getting new developers up to speed in your shop's dev environment? Completely trivial to do with Nix. Getting a machine back up after a failure? Reinstall NixOS and reapply the config you were using (which is in source control). Upgraded Gnome and some things you need broke? Or updated your GPU driver and now your screen just shows black? Simple... Roll back in the bootloader to a previously-working config, then undo your changes to the config definition.

NixOS (and very honorable mention to Guix) are in fact the only ways to run Linux while keeping your sanity intact!

It probably wouldn't be that hard to package.

For example, I committed this to a fork of a C++ package a few days ago just to be able to build it in Nix; it's literally just 1 step away to go from building it here to putting this in nixpkgs but I don't want to be responsible for it (I've also never taken that step yet) and it also doesn't (yet) use Flakes: https://github.com/10gic/vanitygen-plusplus/blob/master/defa...

In theory, though, you'd just have to find a similar Node example out there and crib off its nix config/build file. And if you converted it to a flake, you'd have a guaranteed-reproducible build (but then you'd also be responsible for updating it). Perhaps that's why nixpkgs has one of the highest package counts in the Linux space of package managers.

Not true: there are many tools that allows directly running any binary, like nix-autobahn [1].

Have a look at nix-autobahn and nix-ld.

I haven't tried it yet, but nix-ld and/or nix-autobahn might be (the start of) what you're looking for?
