In this talk Holger Levsen will give an overview about reproducible builds, the past, the presence and the future. How it started with a small BoF at DebConf13 (and before), how it grew from being a Debian effort to something many projects work on together, until in 2021 it was mentioned in an executive order of the president of the United States. And of course the talk will not end there but rather outline where we are today and where we still need to be going, until we'll all be running 100% reproducible software, verified by many.
