This is a sovereignty variant of RKP-3 (Hybrid). The anchoring mechanics are identical - the difference is that all cloud processing and storage runs on OVH rather than Azure or AWS.
Sovereignty Profile
| Component | Provider | Jurisdiction | Notes |
|---|---|---|---|
| Blockchain (on-chain path) | Polygon (PoS) | Global | Distributed network - no single jurisdiction |
| Cloud / API processing | OVH | EU (France) | No US parent; no CLOUD Act exposure; SecNumCloud certified |
| Off-chain storage | OVH | EU | All off-chain data in EU jurisdiction |
| Sovereignty level | Partial EU | EU cloud + global blockchain | Cloud sovereign; blockchain global |
How It Differs from RKP-3 Standard and RKP-3 Sovereign EU
| Property | RKP-3 Standard | RKP-3 Enhanced EU | RKP-3 Sovereign EU |
|---|---|---|---|
| Blockchain | Polygon | Polygon | EBSI |
| Cloud provider | Azure / AWS | OVH | OVH |
| Cloud jurisdiction | US-incorporated | EU | EU |
| CLOUD Act exposure | Yes | No | No |
| Blockchain jurisdiction | Global | Global | EU |
| Full EU sovereignty | No | No | Yes |
| SecNumCloud | No | Yes | Yes |
Architecture
Which Records Go On-Chain vs. Off-Chain
RKP-3 Enhanced EU follows the same routing logic as RKP-3 Standard - the customer configures which event types are elevated to on-chain anchoring:| Record type | Recommended path | Rationale |
|---|---|---|
| Routine telemetry / sensor readings | Off-chain (OVH) | High volume; verification on-demand is sufficient |
| Threshold breach events | On-chain (Polygon) | Likely to face regulatory scrutiny; on-chain timestamp is stronger |
| Alarm and safety events | On-chain (Polygon) | Incident investigation requires blockchain-grade evidence |
| Audit records and compliance events | On-chain (Polygon) | Regulators verifying without accessing your systems |
| Document approvals and signatures | On-chain (Polygon) | eIDAS-aligned timestamp evidence |
| Configuration changes | Off-chain with on-chain snapshot | Routine changes off-chain; periodic state snapshot on-chain |
Regulatory Frameworks Addressed
| Framework | How RKP-3 Enhanced EU helps |
|---|---|
| GDPR | All off-chain processing on OVH - no US-controlled infrastructure in data pipeline |
| NIS2 | EU cloud for critical entity operators; on-chain for the highest-stakes events |
| DORA | OVH removes CLOUD Act exposure; hybrid throughput suits financial data volumes |
| IEC 62443 | EU cloud for OT event processing; Polygon anchoring for alarm and incident records |
| SecNumCloud (ANSSI) | OVH certification for processing sensitive operational data |
| ISO 27001 | EU-resident log processing and storage with on-chain integrity for critical events |
