honestly i think solutions to many of these problems have been put into practice in the cryptocurrency space. there are commercial entities today that i don't have to trust, but will help me set up multiparty signatures for sending bitcoin transactions. i could see a similar mechanism being used for creating/revoking/recovering a compromised identity. hierarchical deterministic wallets seem a decent blueprint for identity. if i can generate arbitrary pubkeys from a single seed, then i maintain my privacy across providers i use my identity with. i used to think that the blockchain itself could make for a decent revocation list, but i don't think that's even neccessary. maybe it's simply time for governments to grow up and accept that the internet is critical now and as such provide basic digital identity services as they do with travel documents today. it doesn't have to be perfect, just publish revocations on behalf of citizens.
