My wife asked me what I'd been working on. She is not at all technical and her eyes glazed over immediately, so I asked an LLM to ELI5 it and tailor it to her profession. Here we go:

Nostr: You know how if the company switches banks, you have to set everything up from scratch with new signature cards, new logins, new everything? Nostr is like having one signature that works at every bank. You're not locked into any single institution—your identity belongs to you, not them.

Your key: It's basically your signature authority. Whoever has it can sign off as you. So you really don't want to hand it out.

Bunkers: Think of it like keeping your signature stamp locked in a safe that only you can open. When an app needs something signed, it sends you a request—like an invoice hitting your approval queue. You review it, approve or reject, and the safe applies the signature. The app never gets direct access to your stamp.
