Yes exactly! For backing up sensitive data like a digital will or encryption keys.

Sorry to miss this! Is there like an email notification I can get when there are more Folk Tech events? I'm not on Bluesky or social media much these days.

There is still a ton of work to do but having the core flow working makes all the future changes feel small and incremental by comparison.

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.

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.

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 first is a backup tool that uses Shamir's Secret Sharing algorithm to distribute secrets among groups of friends for maximum privacy and resilience. (2/3)

Wow yes I love these ideas. I didn’t even think about the fact that someone could compute these proofs for a chain that isn’t theirs. It’s such black magic.

Ah I love finding other scuttlebutts in the wild ❤️. I only know about crypto/protos because I have been playing with them the same as you haha.

This is one of the longstanding onboarding problems with SSB. You follow a few people and suddenly you have 100k JSON messages to download, parse, verify, and index before you can display recent content.

🤔 but a merkle root doesn’t prove anything to a peer without the whole chain right? It would be useful to quickly verify that two peers have the same chain, but I’m imagining a scenario where a peer can fetch just the last few messages on the chain but still know they are part of a valid chain.

But now you have my gears turning... why can't we have some adjacent channel for signed zk proofs that solve the initial sync problem on SSB? Like for every message I add to my chain I also publish a zk proof that it's a valid part of the chain, so it would be backwards compatible?
