What interesting computer science problems arise in Nostr development? I'm thinking of putting together a talk on this for CS folks that aren't familiar with Nostr. Here's what I have so far, and please suggest new items or revisions to current ones:

- public/private key encryption schemes between individuals, groups, groups with moderators, temporary delegations of key signing (#nsecbunker)

- graph analysis and scoring to solve problems like web of trust (#WoT)

- distributed file storage and sharing, like what #blossom is trying to do

I know there's got to be a lot more, 🙏 in advance
