IXO Ontology

The semantic operating layer for cognitive digital twin systems. It expresses a shared vocabulary for entities, relationships, claims, evaluations, and executable protocols.

What this enables

Data graph icon

Cognitive Digital Twins

Represent real-world systems of agents, devices, projects, financing mechanisms, organisations and places — each identified by a DID in the Interchain Identifier (IID) registry of the L1 Impact Hub blockchain network. CDTs are embued with governance controls, services, linked resources, linked claims, object capabilities, economic accounts, and graphs of relationships.

Verifiable Data Models

Claims-first data fusion from external sources, to provide verifiable ground-truth and situational awareness, with content addressing and proofs (CIDs) for large artefacts. Builds semantic and directed acyclic graphs representing real-world state changes.

Oracle Evaluations

Agentic Oracle services implement verifiable protocols —inc using with zero-knowledge proof of execution (PoE), to produce auditable judgments that include P‑values and method metadata, together with zero‑knowledge attestations where applicable.

Executable Protocols

Protocols are activated as deeds that provide the instructions, services, resources, capabilities, and economic incentives to process claims, automate reviews, execute approvals, handle disputes, and trigger event‑driven payments via smart accounts.

Tokenised outcomes

Outcome indicators are tied to issuing digitally certificates in the form of verifiable credentials, then minting ERC‑1155 impact credits or outcome units when verified thresholds are met, as defined in executable protocols.

Data sovereignty

Federated, end‑to‑end encrypted data exchange (Matrix), with minimal on‑chain anchoring for integrity and coordination.
