A context/reaction tree as a ZK proof of expertise
If you keep a careful tree of your context and reactions (https://andysmith.ai/2026/Aug/16/context-as-a-separate-stream-of-events/), you can use it as proof of competence.
It could even become a new kind of résumé.
Say I'm an expert in AI, and I also know how to build birdhouses. But for some reason I'd rather not make that public. Maybe it gets in the way of how I want to position myself.
Then life takes a turn. I need to build a birdhouse, and I've found funding. Now I have to prove I'm an experienced birdhouse builder. So I reveal part of my context and reaction tree. (You could just call it that, an experience tree, or an experience lake, like a Data Lake.)
The main thing is to avoid a leak. If I use ZK to reveal this data to someone, that someone can't then go and publish the proof. Especially if the fact that I can build birdhouses could hurt me somehow. (I'm mostly thinking about reputational risk here.)
The context tree gets collected anyway. The only question is how to store it and manage access to it so this works without any extra effort.
