I'm interested in this space too. I think nostr:nprofile1qyw8wumn8ghj7cm0w4h8gunfv4ejuenfv96x5ctx9e3k7mf0qyxhwumn8ghj7mn0wvhxcmmvqqsqlzkn2zk6yv9ll73lguqf7vqy4nj5qmyajxnf2aam9ffdzc0tecc888xk2 and npub12mllp29adf2fw0eeahmseczcu3y4625qyn3v4uwfvkpzlshnmj3qs903ju are doing interesting things in this space.
