Identity looks like a potentially interesting use case. https://www.computerworld.com/article/3244128/how-blockchain-makes-self-sovereign-identities-possible.h

  This totally collapses for most real world uses of identity. If it's used for anything important then you need to be able to recover your identity if your house burns down with your keys inside or you lose your passphrase due to brain injury (or you just forget). You need centralization for most real-world uses of identity. Could you have an identity where if the above happens you just start over? Yes, as long as it's not "too" expensive. But if you make it too cheap you risk Sybil attacks. So your identity system can't really be used for reputation. What's left? Not much IMO. Timestamping use cases like 'I created this work of science/art at this time and I can prove it' are good, especially if you broker with an agent that can reliably and securely store keys. Identity is hard IMO.

    > Could you have an identity where if the above happens you just start over? Reading the W3 spec for Decentralised Identifiers is probably a bit dry, suggest looking into other sources on this matter. Regardless the answer to your question is yes. A lot of smart people have been working on this very thing for years. https://www.w3.org/TR/did-core/ https://www.w3.org/TR/did-core/
