The verified-asset rail architecture generalizes. Housing is where it shipped first. These are the applications we're actively researching — some pre-product, some in pilot design, all built on the same core primitives.
Every pillar has a status label. Shipped means the product is live. In pilot design means we're designing a first partner engagement. Research means we're mapping the domain and prototyping — no product to buy yet.
The category-defining application. Keystone is the shipped product: registry, capital rail, disbursement rail, insurance rail, and the Modular Index. Every module built on the factory line gets a signed, hashed, KeyScore-scored record; five downstream engines read it.
Today Keystone ingests via CSV bulk import and the ingest API. The next step is a cyber-physical-system node that sits on the factory floor, watches sensor + inspection outputs live, and writes signed records into the registry as the line produces. Zero human-in-the-loop for the mechanical work; humans do the exceptions only.
The EU Battery Regulation begins enforcing mandatory digital passports for in-scope batteries on February 18, 2027. Five data domains, three tiered access levels, hash-anchored lifecycle records. The verified-asset rail primitives fit the regulation almost verbatim; we are designing a Keystone-family module that ships an EU-compliant passport per unit.
$1.2 trillion authorized under IIJA. Drawdown consistently lagging schedule. IRS auditing every §45X domestic-content claim per-unit. The unifying operational fix is the same primitive Keystone uses for HFA disbursement: gate release on a verified record instead of reconstructing evidence forensically after the money moves. We are researching what a federal-scale deployment of that pattern would take.
A $40–60B market with no shared verification infrastructure. Every refurbisher grades bespoke; every buyer underwrites bespoke; pool financing is structurally unavailable. Same architecture that unlocks modular-construction financing unlocks this one — a per-unit verified record with a common scoring layer. We are mapping the incumbent grading systems today and designing the scoring model that would collapse them.
The pattern behind every pillar is the same: find the seam where operational systems produce real data but a downstream party (capital, insurance, government, buyer) can't use it in a usable form. Prototype the missing rail as bespoke, single-tenant, internal infrastructure inside one partner. Once the primitives stabilize, extract them as a neutral product with a licensed-partner posture — someone else holds the regulated license, we hold the data infrastructure.
Keystone is the finished version of that method applied to industrialized construction. The four pillars below it are earlier stops on the same path. None of them requires new fundamental research; all of them require operational discipline, domain literacy, and the willingness to sit inside a real production process long enough to see the seam clearly.
If you have production or regulatory data and a specific verification problem to solve, we want to talk. Book a research conversation.
Five minutes from signup to your first KeyScore. The same record then flows through underwriting, disbursement, insurance, and the index — without re-entering data anywhere.
