What does BLOB stand for?

Need to compare hashes between a stock ISO and one ~~flashed~~ booted by Ventoy (dd the latter to a file and check)

This is a bit absurd. I really don't think this is as serious as some comments say. Also there is a comment from AUR package manager which explains more details. . And even the blobs in the first post there are source and build instructions in their respective folder.

I like multiboot. Used it back when I used Windows.
The Ventoy advertisements on Reddit looked too suspicious, so I never checked it out.

I've had too many issues with Ventoy that I'd rather just use fedora media writer or balenaetcher for when that doesn't work. I mean honestly it's a bit gimmicky, even if it's a cool concept. I believe Glim and some other options exist too

It's a useful tool, but there is a security concern for anything not fully open source. You will have to weigh your risk factors, I doubt that it's any problem for most consumers or distro hoppers.

Best to keep an eye in case any new contributers arrive suddenly...

Is BLOB an acronym?

I just wish it had a real alternative. GRUB on USB doesnt support as much distros or windows.
