"There’s always been a gap between what’s possible with crypto and what people actually do, largely due to poor user interface. There has to be a better way for people to acquire a user’s keys other than some crazy web of trust.
Whether you want to give someone SSH access to a machine, or you’re downloading software from the internet that you need to use in your own software - something as simple as JQuery - proving rightful ownership of keys is difficult. There are a number of times that we found this problem with keys, and we thought it was a common pain point, particularly for programmers.
There are aspects of your identity which we can probably connect with your public key, such as your Twitter. You’re known to have a certain Twitter account. I should be able to send bitcoin to a certain Twitter user and know that I’m getting a bitcoin address that they truly own."
