# The Ownership Operating System

> Strata is not four protocols — it is one coordinated system of specialized engines.

Strata is built as a single **Ownership Operating System**: four specialized
engines connected by shared control planes, liquidity, and data layers. The
engines are independent enough to be governed and risk-managed separately, but
interoperable enough that origination, credit, liquidity, and settlement
reinforce one another.

## The four engines

<CardGroup cols={2}>
  <Card title="Tokenization" icon="layer-group" href="/products/tokenization">
    Asset onboarding, SPV lifecycle, KYC, and the engine that turns a real-world
    asset into a structured, investable vehicle.
  </Card>

  <Card title="Money" icon="coins" href="/products/money">
    Issuance of srUSD, the commodity-backed settlement dollar and the system's
    control plane for supply.
  </Card>

  <Card title="Credit" icon="building-columns" href="/products/credit">
    Asset-backed credit origination and underwriting against real collateral.
  </Card>

  <Card title="Markets" icon="arrows-split-up-and-left" href="/products/markets">
    Liquidity, structured products, and protocol-owned-liquidity management.
  </Card>

## How they relate

The system has a clear division of labor:

| Layer                   | Role                                              |
| ----------------------- | ------------------------------------------------- |
| **Money**               | Control plane — issuance authority for srUSD      |
| **Markets**             | Liquidity and financial primitives                |
| **Credit**              | Asset origination                                 |
| **Structured products** | Financial-engineering layer (tranching, leverage) |

<Info>
  **Core insight:** Money is the control plane that gates issuance; Markets
  provide liquidity and primitives; Credit originates assets; and the structured
  layer engineers the payoff. No single engine is the product — the coordination
  is.
</Info>

## Shared primitives, built once

Several primitives are built once and reused across every engine. This is what
makes Strata a system rather than four disconnected forks:

<AccordionGroup>
  <Accordion title="Global control plane" icon="sliders">
    A money-policy controller and engine registry enforce global caps, throttles,
    and issuance gating across every engine that can touch srUSD supply. Defined
    first, because everything eventually touches issuance.
  </Accordion>

  <Accordion title="Oracle & risk framework" icon="gauge">
    Oracle adapters, risk-config registries, and asset-approval frameworks shared
    across all forks. The oracle and risk layer is the real protocol; the forks
    are execution engines.
  </Accordion>

  <Accordion title="Registry layer" icon="table-list">
    A unified registry pattern indexes every deployed financial object — markets,
    engines, risk configs, and fee configs.
  </Accordion>
