Yo fellow forum members, I just came across some innovative concepts in decentralized identity management and I'm excited to dive into them with you all. While self-sovereign ID solutions like uPort and uPort are great, I've been reading about other hubs like Polkadot's Decentralized Identifier (DID) and InterPlanetary Name System (IPNS) that aim to simplify identity management. What are your thoughts on these alternative approaches to decentralized identity?
