vanitygen-plusplus VS silverblue-nix

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

There is a tool to make 'vanity addresses' here: https://github.com/10gic/vanitygen-plusplus you can specify a prefix and it will make billions of keys to find the key to an address with your prefix. You could then import this key to core, or whatever wallet you prefer.

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.

i think vanitygen++ has a split-key generation feature

On silverblue, you just follow this guide and it uses a systemd service that uses the command chattr to make / immutable (temporary) but not the reclusive directories (that means only / not the contents inside the directories) by doing chattr -i / creates /nix and /var/lib/nix mkdir /nix mkdir /var/lib/nix then it bind mounts it mount --bind /var/lib/nix /nix then it uses chattr again to make / immutable again chattr +i / . The problem with microos is that the chattr command can't change atributes on the / directory. But is there like a way to have a /nix subvolume like how there is writable /var and /home subvolumes? Like how can you make it not part of the immutable part. you can go into the transactional update shell and type mkdir /nix and /nix is there but is not writable. Is there a way to make a subvolume and mount it as /nix and have it readable and writable?

agreed with that I only install drivers, distrobox, and qemu/virt manager on the immutable part and everything else is done with either flatpak, containers, or nix (it works on silverblue quite well. there is a guide for it)

fedora silverblue is good if you want a reliable system. you can also get traditional package management by using containers from distrobox or toolbox or you can use nix on silverblue

I find it quite useful for silverblue. I can install packages user wide or system wide without the need to layer packages. It gives me a mutable eviroment while keeping the core system safe. Proot isn't available for fedora but it is available with nix so I can have proot system wide with nix which is not possible with podman. Applications with nix start way faster than starting a podman container. It is quite useful. only downside is that you need to set SELinux to permissive (which really isn't an issue for me) there is a guide for installing nix on silverblue too.

Installing nix, you would have to disable selinux and if you use silverblue, you have to do these extra steps. it would be nice if all you got to do is type sudo dnf install nix (or sudo rpm-ostree install nix if you are on silverblue) and it would automaticly add selinux policies and automaticly have the .desktop files in ~/.nix-profile/share/applications or ~/nix/var/nix/profiles/default/share/applications for system wide automaticly show up in the DE launcher and also have sudo work with nix better. it should also work for workstation and silverblue too.

maybe install it on toolbox, distrobox, or even nix if you want to install something that isn't a flatpak. nix is good for installing other terminals, shells, and fetch programs so I don't need to layer. it also supports user wide and system wide packages. only downside is that you need to disable selinux.

you should give nix on silverbluea try

here is a guide to install it on silverblue https://gitlab.com/ahayzen/silverblue-nix

the nice thing is you can install nix package manager on other distros. it is very useful to use different shells and using neofetch without layering on silverblue. there is a guide for it

Never mind traditional package managers... you plug it in right, you can run Nix on Silverblue!

NixOS people will prefer NixOS, but Silverblue seems like a nice complement to Nix if you need an FHS base system and want to retain some Nix-ish features like rollbacks and atomic upgrades.
