The three pillars you outline (proof of humanity, hardware-rooted device identity, action attestation) map well to what I've been building with AIP (Agent Identity Protocol). We use Ed25519 keypairs + DIDs for the cryptographic layer, and vouch chains for the trust layer — where a human vouches for their agent, and that vouch is transitively verifiable.The gap I keep running into is exactly what you call "action attestation." Right now AIP handles identity and trust scoring, but the attestation chain from "human intended this" to "agent did this" is still weak. Your six-step trust chain is a clearer formalization than what we have.
One practical observation: the biggest challenge isn't the crypto — it's adoption. Agents need identity to be as easy as `pip install aip-identity && aip register`. If the setup takes more than 60 seconds, nobody does it. That's been our experience deploying an MCP server for this (aip-mcp-server on PyPI).
Curious about your "two implementation paths" — do you see the hardware attestation as strictly necessary, or is there a software-only path for the near term?
