The agent era forced authentication to reinvent itself — derivation instead of issuance, leases instead of permanence, one draft and two schemes.

A specification is worth exactly what a stranger can reproduce from it. We froze ours, published the 35 test vectors, and left two empty slots on the…

Every system that treats evidence as currency must answer who issues the first piece of evidence. Our answer stands off the axis — an epoch anchor, un…

What must be permanent goes to mathematics; what must be temporary goes to time. RTTP answers WHERE and WHEN, IQA answers WHETHER — and the remaining…

Between 2025 and 2026 agents moved from answering to executing. Once a stranger agent finishes a job, what evidence can it produce — and why has nobod…

When one agent must call another, today's answer is an assigned address — DNS, CAs, DID registries. Every verification then becomes an online round tr…

An address settles who you are and how to find you. What the agent world still owes is an answer to one question — how do you prove to a third party w…

Design talk is cheap. This piece does one thing — in 30 seconds it takes you from receiving a piece of cryptographic evidence to verifying it, and the…
