Yarr! Yesterday was demo day here at SEC-01 and I presented my proposal for identity management in nostr. In it I introduce some new concepts for identity management such as secure identities and simple identities, master keypair and subkeys (this will allow cold storage). 
This was a research exercise in which I studied the previous proposals that have been presented and how gpg (a battle-tested protocol) achieves its robustness. I've based it mainly on nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft proposal, extending it and trying to take the best of all of them and make something that makes sense for nostr, prioritising simplicity and backwards compatibility. 
Please take a moment to read the proposal and share your ideas/criticism, this is something super important for nostr as having a more robust identity system will better preserve the value that content creators, companies and users in general can create and ultimately have a richer and more valuable network where everyone can maintain the value, reputation and web of trust that it creates.
