Filming a Video Essay on Paxos (and Why It Took Six Weeks)

The hardest part of explaining Paxos on camera isn't the algorithm — it's deciding what to cut. Every simplification risks teaching something subtly wrong, which matters more on video than in a paper, because most viewers won't go read the original source afterward.

I ended up building a small browser visualization just for the video, the same one that later became the seed for ConsensusKit. If an explanation only works with animation, that's usually a sign the algorithm's real complexity is in the timing, not the logic — which was exactly the lesson worth keeping in the final cut.
