I just want more trustworthy systems. This particular concept of combining reproducible builds, remote attestation and transparency logs is something I came up with in 2018. My colleagues and I started working on it, took a detour into hardware (tillitis.se) and kind of got stuck on the transparency part (sigsum.org, transparency.dev, witness-network.org).

Then we discovered snapshot.debian.org wasn't feeling well, so that was another (important) detour.

Part of me wish we had focused more on getting System Transparency in its entirety in production at Mullvad. On the other hand I certainly don't regret us creating Tillitis TKey, Sigsum, taking care of Debian Snapshot service, and several other things.

Now, six years later, systemd and other projects have gotten a long way to building several of the things we need for ST. It doesn't make sense to do double work, so I want to seize the moment and make sure we coordinate.

These kinds of problems are very common in certain industries.
