Sustained under SLH-DSA 128f post-quantum signatures. 40× Hyperledger Fabric. Independent benchmark underway - report Q3 2026.
Q Day
NIST FIPS 203/204/205 shipped in production today. Fabric and Corda have post-quantum cryptography on roadmaps. Chinese ledgers are years behind.
100 %
EU-sovereign by design. Keys never leave the European consortium. Any infrastructure — AWS, Azure, GCP, EU sovereign cloud. Zero non-EU root-of-trust.
For Industrial Enterprises
Meet the AI Act, NIS2, CRA, and eIDAS 2.0 obligations with cryptographic proof — not contractual assurances.
FileChain's 4 distributed ledgers (cyber, workflow, provenance and ownership) are integration-ready today.
