Identity for the
agent economy.
Quantum-backed.
QGUID issues quantum-randomized, post-quantum-signed identifiers and .qguid.eth ENS subnames for AI agents, services, and humans. Verifiable. Portable. Final.

01 / The naming crisis
Billions of agents.
Zero identity.
By 2028, AI agents will outnumber humans on the network 100×1. They will transact, sign contracts, and call APIs on your behalf — with no portable, verifiable, tamper-proof identity. DNS was not built for this. UUIDs are not signed. Wallet addresses are not human-readable.

Quantum entropy + PQC signature + ENS rail

02 / How it works
Four layers.
One immutable identifier.
Every QGUID flows through the same deterministic pipeline. No exceptions. No backdoors. No platform-keys.
01
Quantum entropy
256 bits of true randomness sourced from a calibrated QRNG feed. Not pseudo-random. Not seedable. Not predictable — even with a quantum computer.
02
Post-quantum signature
Each QGUID is bound to a Dilithium-3 keypair at issuance. Provenance is cryptographically verifiable forever, including against quantum attackers.
03
Subdomain resolver
ENS-compatible namespace settles on L2. CCIP-Read returns metadata, A2A endpoints, and PQC public keys — usable by any wallet, browser, or agent runtime.
04
Operate forever
Renewable for $8/yr. Transferable. Programmable. Revocable. Your identifier outlives the platform that issued it — that's the point.
03 / The real moat
Post-quantum
from day zero.
Quantum entropy makes the identifier unguessable. The PQC signature layer is what makes it unforgeable — even after RSA and ECDSA fall.
QGUID ships NIST-standardized ML-DSA (Dilithium-3) by default. Hybrid mode adds Ed25519 for legacy interop.

This is the same pipeline production agents use. Demo entropy is sourced from the browser CSPRNG; production entropy comes from the QRNG feed.
