I'm an ophthalmologist. I look at irises all day. People's irises change over the course of their life. Sometimes dramatically if they have some kind of pathology. Are they updating their model periodically? What keeps someone from getting locked out of their crypto gains if they develop an iris nevus or have cataract surgery or start on flomax?

The iris thing is only used to open an account to stop you getting multiple accounts. After that access is private key. Maybe I'll try going back for a second account!? My irises may be different enough 2 years on?

I presume that you would want your crypto gains to require “proof of identity” to access, not just “proof of humanity”, which is what World provides.

Also, once you have generated keys with your eyes, you use the keys, not your eyes, as tokens to validate your humanness.

Thanks for this interesting point of view. However, it may makes sense to consider whether the gap you point to can be reduced significantly with AI, by training it separately with aging eye data using existing medical data independent from the general iris pool. I have no idea how realistic that would be personally.

Are you willing to gatekeep you wealth behind an AI that might hallucinate that your iris has changed more than it actually has?

I wondered this with things like FaceID. In my head, every time it unlocks it’s tweaking and tuning the what it knows to be the user, so it can adapt as a person ages, goes through weight changes, etc. However, in practice this may not be the case, since there is an easy backup and a person can re-register pretty easily.

On the topic of eyes, my dad recently had surgery on his eyes and they did one at a time, for obvious reasons. That could be a way to transition. Register both, have surgery on one, let it heal, register the healed eye, have surgery on the other, then register that. Always using the good and registered eye to authenticate. But this isn’t realistic. It requires way too much forethought and planning, when people’s minds are elsewhere.
