There's also the potentially interesting idea of wallet-as-resume. IE allowing different types of access depending on what sorts of things you've done with your wallet in the past. Certainly not for all applications, but a certain level of implied competency might be appropriate in some cases.
I've heard that one before... I've yet to hear a "how is it better" set down in a way that describes the architecture in a way that can be explored with more than handwavium.
How does "wallet as resume" solve the implied competency better than a GitHub repo with signed commits?
How does the wallet-as-resume solve the "I copied a project" or "I followed the tutorial line for line?" One can create a NFT or whatever equivalent for code you wrote just as easily as code you copied (be it with cp or typing it all in yourself). Can only one person would be verify a particular implementation of FizzBuzz? If the code is copied, can the original author usurp the "I wrote this" from a pretender?
Does anyone reading resumes actually think that this is a problem that needs solving?
"Service X preemptively bans me because I signed up for service Y with my wallet" sounds like the opposite of censorship resistance and decentralization.
It should be possible for each person to create multiple digital identities and have them linked using zero-knowledge proofs. If we can solve the messy problem of giving everyone (arbitrarily many uncensorable pseudonymous) IDs with their own key pairs, it should be relatively simple to layer on top of that all the functionality and privacy guarantees we would want from an ID system.
For example, once a reasonable digital ID system exists, we can start to build trust systems, such that your good reputation among one community can be used to bootstrap your reputation in a new community. Again, zero-knowledge proofs should be a viable mechanism for conveying trust relationships without having to reveal your social graph.
Some of this data would have to be stored off-chain, or only in encrypted form on-chain, but I don't think there are any practical limits of blockchain technology which prevent this.
I'm all for services making that kind of decision as opposed to government, but this is also a bit of a misnomer because you can have multiple wallets.
