Discover the cutting-edge technologies powering the Datalium platform.
At the heart of Datalium lies Hyperledger Fabric, an enterprise blockchain developed by the Linux Foundation. Unlike public blockchains like Bitcoin or Ethereum, Hyperledger Fabric is designed for enterprise applications.
Over 7,000 transactions per minute
Private channels for sensitive data
Flexible plug-and-play architecture
Enterprise Blockchain
A modern architecture designed for performance, security and scalability.
Our backend is built in Rust, a modern systems language that guarantees memory safety without sacrificing performance. With Rust, we achieve millisecond-level response times.
Open source relational database recognized for its reliability and performance. PostgreSQL stores user metadata and certification history.
Infrastructure hosted on Ubuntu Server LTS for maximum stability, regular security updates and optimal Docker compatibility.
Containerization with Docker for reproducible deployment, service isolation and simplified horizontal scaling.
End-to-end encryption with SSL/TLS certificates. All communications are secured via HTTPS with automatic Let's Encrypt certificate renewal.
Responsive and intuitive user interface built with the latest web technologies. Compatible with all browsers and devices.
FOLD, our digital identity wallet powered by Datalium, is built on a Zero-Knowledge architecture. This means your data is validated without ever being revealed. Even Datalium cannot access your documents — it's technically impossible.
Validation without revealing content
Military-grade encryption with TOTP keys
Password + FaceID + Recovery questions
Automatic purge, zero server persistence
No tracking, no logs, no resale
We tested every attack scenario. Your identity remains protected in all cases.

A defense-in-depth security approach to protect your data.
JWT + Argon2 for ultra-secure passwords.
AES-256 + TLS 1.3 for all communications.
SHA-256 for data fingerprints and TOTP keys.
Distributed consensus for immutability on our proprietary chain.
The European Union mandates digital identity for all citizens. The eIDAS 2.0 regulation, adopted in 2024, requires digital identity wallets to be available by 2026 and adopted by the private sector by 2027 — with 80% of citizens onboarded by 2030.
FOLD by Datalium is designed from the ground up to be fully compliant with eIDAS 2.0, GDPR and biometric privacy regulations. Our architecture ensures compliance is built into the technology, not bolted on afterward.

Private permissioned blockchain with 7 distributed EU nodes and capacity of 10M+ records per day.
Each block contains: index, UTC timestamp, AES-256 encrypted payload, SHA-256 link to previous block, SHA-256 hash and Ed25519 node signature.
7 nodes with master rotation every 5 minutes. Automatic failover on failure. Batch writes of 500 blocks with PostgreSQL + JSONB storage.
P2P sync: fanout 8 peers/hop, TTL 4 hops (4,096 node reach), dedup cache 10,000 msgs/60s. Integrity checks every 30 seconds.
10M records/day. 115+ blocks/second. 5 TB daily storage capacity. 1.8 PB annual capacity. Health checks every 15 seconds.
Multiple recovery methods ensure you never lose access to your identity.
SHA-256(doc) + Phone TOTP. QR code scanned by verifier. For daily use, instant verification.
SHA-256(FaceID) + Middleware TOTP. Face scan + email verification. When phone is lost.
SHA-256(personal info) + TOTP. Last resort when phone is lost and no FaceID.
