The European trust layer for AI and industrial data.

Cloud and AI Development Act (CADA), Open-Source Strategy, Chips Act 2 — defining for the first time what qualifies as fundable sovereign infrastructure.

FileChain satisfies the CADA Sovereignty assurance levels.

Europe's trust infrastructure primitive is already built.

Airbus - ASML - Ericsson - Mistral AI - Nokia - SAP - Siemens (€1.1T market cap, €40B annual R&D, explicit urgency) called for trusted technology, breakthrough flagship projects, and EU IP control this June 2026.

FileChain is the trust primitive that coalition needs and currently lacks.

$6.8B -> $150B at 45 % CAGR. The West is 5-7 years behind. The 24-month window of opportunity for FileChain is now. Otherwise major US and Chinese players will soon dominate the digital trust infrastructure all over Europe.

FileChain enables cryptographic chains of custody for AI training data & AI actions from agents. No architectural change to AI systems.

And AI Act Article 50 obligations becoming mandatory on 2 August 2026 forces urgency and proactive action today.

FileChain enables immutable cross-organization audit trails. Partners need not share nor expose all data on a common platform.

FileChain enables cryptographically verifiable SBOM attestation at each stage of the software supply chain.

FileChain supports NIST FIPS 203/204/205 post-quantum signatures in production today to enable cross-border digital identities and digital product passports (DPP) for data with +10 years sensitivity horizon.

FileChain is the only European permissioned ledger with post-quantum cryptography in production and EU-sovereign key management across all 11 CER sectors.
