> I think it's a particularly novel idea of using on-die fuses to prevent firmware downgrade. I don't know how common that is in the console security world As far as I know, it's been standard practice ever since consoles started having firmware updates. They don't necessarily blow fuses in the update procedure, but they'll generally fuse off anything below the version that a given unit shipped with.
