The Protium Stack
AI, LLMs
and data access.
One managed stack.
The platform makes trust and participant autonomy operational across an ecosystem. Credentials establish who may act; access policies define the scope; isolated tenants preserve organisational boundaries.
The credential and tenant layers operate across Protium managed services. AI authorization is available for scoped rollout.
AI & LLM Layer
Credential-based authorization for scoped AI-agent and MCP rollouts.
Explore layer →Trust & Credentials
Credential issuer and authorization registry on W3C Verifiable Credentials, with certified trust-framework roles (iSHARE v3). 100% Protium IP.
Explore layer →Ozone Platform
Tenant delivery engine — a dedicated, isolated runtime per customer. Identity, credentials, service registry, real-time layer.

Standards compliance
W3C Verifiable Credentials
The open credential model at the core of the stack.
OID4VCI
OpenID for Verifiable Credential Issuance.
DCP
Decentralized Claims Protocol — issuance and presentation for data-space participants.
SD-JWT
Privacy-preserving, selectively disclosable credentials.
EUDI Wallet ARF
Aligned with the European Digital Identity Wallet reference architecture.
iSHARE v3
European trust framework for data spaces — Protium is certified on two roles.
MCP-compatible
Authorization layer for the Model Context Protocol ecosystem.
EU Data Act
Applies since 12 September 2025 — our stack makes its data-access obligations operational.
Built for European data sovereignty
Services are deployed in the EU. The stack uses W3C Verifiable Credentials, OID4VCI, DCP and SD-JWT patterns, with certified iSHARE v3 roles where a data space requires them. Specific residency, certification scope and EU Data Act responsibilities are confirmed during architecture and compliance review.
