About

I'm Blake.

I build ~alter. It's a protocol for human and agentic identity, designed around my formal theory of identity (the eight papers here), and it's where most of my time goes.

The short version: no more passwords, usernames or sign-up forms. One ~handle is your login and your address everywhere. Your AI can't act in your name without you saying yes with a tap on your phone, and the record of who you are belongs to you, not to us.

It isn't a crypto company and it isn't an AI company, though it's built for both. We don't run a single AI model anywhere in it.

The Internet-Drafts are my proposals to the IETF for how this should work between everyone's systems.

If any of that is your kind of problem, write to me. Happy to chat.
