Brave has no official tutorial on how to set it up on OpenSUSE, so here's a short snippet on how to do that. This does work on my fresh Tumbleweed installation (06/27/2019).
sudo rpmkeys --import https://brave-browser-rpm-release.s3.brave.com/brave-core.asc
sudo zypper addrepo https://brave-browser-rpm-release.s3.brave.com/x86_64/ brave
sudo zypper install brave-keyring brave-browser
I'm having a lot of fun with the Unsplash image search by the way.
