Data on a European server is not automatically European. The US CLOUD Act compels American cloud providers to hand over data to the US government — regardless of server location. European supervisory authorities imposed over €7.1 billion in GDPR fines in 2025, a significant share for cross-border transfer violations. The question is no longer whether data leaves the EU — the question is whether organizations can prove it when it happens, and whether they can demonstrate that the legal basis was valid at the time of transfer. Meta's €1.2 billion fine in 2023 set the precedent: paper compliance is not enough.
Michael and Nadine walk through the full legislative framework: GDPR Chapter V with its Schrems II obligations (Transfer Impact Assessment mandatory for every Article 46 transfer), the EU Data Act (Regulation EU 2023/2854, applicable from September 12, 2025) requiring cloud providers to block non-EU government access to EU-stored data, and the Data Governance Act as the foundation for European common data spaces. They cover GAIA-X Trust Framework 3.0 "Danube" (November 2025) and the 15+ operational European data spaces — from Catena-X in manufacturing to GAIA-X Health. And they draw the critical distinction: data residency means your data sits on a European server. Data sovereignty means your data is demonstrably subject only to European law — and those are two fundamentally different things.
The core insight: contracts, SCCs, and TIAs prove intent, not execution. Supervisory authorities ask for technical evidence of actual data transport. Attesto delivers that layer — tamper-evident logging of every data event as cryptographically irrefutable proof via the Proof of Evolution system. The Nova/IVC layer is already running live in production.
