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
When to choose this variant: You need the throughput efficiency of the hybrid model - off-chain for bulk data, on-chain for critical events - and require that all data processing and storage occur on EU-incorporated infrastructure, while the on-chain anchoring layer (Polygon) is acceptable as a global public network.
