Valve is generously providing backing for two
critical projects that will have a huge impact on our distribution: a
build service infrastructure and a secure signing enclave.
The enclave is essentially intended to be a way for us to PGP-sign packages with a single signing key instead of how we do it right now, which is with one personal key per packager. It will not benefit Proton or the anti-cheat situation in any way and is completely unrelated.
