I've finished my first round of interviews for Keydex and they were so enlightening. I'm so addicted to user interviews now, I don't understand how I made so much software without them.
The top insight from this round was clarifying the different use cases for Shamir's Secret Sharing. Here's what I came up with:
- inheritance planning
- corporate secret management for ultra-sensitive values i.e. root passwords
- border crossings
- web3/crypto/Nostr key backup
The most interest by far was in the inheritance planning use case. People have some digital stuff they want to pass on, but don't want it sitting in plaintext in the hands of (generally very normie) friends and family. Keydex will work for all cases listed above but I'm going to keep the inheritance use-case top of mind while developing. Which already invalidates some of the design work I did last week. I was going to make a fun retro/gamey UI, but now I'm going to shift towards something more calm and reliable.
