From PDF to Blockchain: Streamlining B2B Flows with zkBDI

A deep dive into secure, automated data exchange using zero-knowledge proofs

In an era where B2B data exchanges are becoming increasingly complex while demanding higher security, zkBDI Protocol emerges as a game-changing solution.

Smart data extraction, verified business identities, Zero-knowledge privacy, all working together automatically.
In our live interactive demo, you’ll experience how a simple PDF becomes a fully traceable, blockchain-secured B2B exchange, ready to plug into your systems.

Smart Invoice Data Extraction Start by uploading an invoice PDF.

Our system automatically extracts structured data while preserving business context:

• Parties – Issuer & receiver details (name, tax IDs, addresses)
• References – Invoice number, order number, due dates
• Items – Descriptions, quantities, pricing, discounts, VAT
• Totals – Calculated amounts and tax breakdowns

Unlike basic OCR tools, our AI understands business semantics, ensuring the extracted data is instantly usable across downstream systems.

👉 Don’t have a sample invoice on hand? No problem — the demo lets you load a pre-filled example to test the full experience in seconds.

Intuitive Editing & Validation A clean, user-friendly interface allows you to:

• Fix extraction errors (rare, but possible)
• Add/modify line items
• Adjust VAT rates, discounts, and payment terms
• Auto-calculate totals in real-time

This step ensures data accuracy before exchange, reducing reconciliation headaches.

Multi-Format Export for Easy Integration zkBDI supports all major B2B standards, making compliance effortless

✅ UBL 2.3 (Global e-invoicing standard)
✅ CII (UN/CEFACT Cross-Industry Invoice)
✅ TEIF (Tunisian E-Invoice Format)
✅ EDIFACT (D96A) (Legacy EDI standard)
✅ JSON/XML (API-friendly formats)
✅ CSV (Universal compatibility)

Need just one piece? Our modular web services let you integrate only what you need—whether it’s extraction, conversion, or validation.

Blockchain-Secured Sending with Zero-Knowledge Proofs This is where zkBDI truly innovates:

1️⃣ Decentralized KYB Verification – Validate business identities via zkBDI Business Ident
2️⃣ Asymmetric Encryption – Data is encrypted with the recipient’s public key
3️⃣ Immutable Timestamping – Transaction recorded on BNB Chain for auditability
4️⃣ Zero-Knowledge Proofs – Verify data authenticity without exposing raw content
5️⃣ Automated Notifications – Recipients get an email with a blockchain transaction link

It’s like proving you know the secret without revealing it.

Why zkBDI beats traditional solutions

Privacy by Design, Unlike SaaS platforms that store your sensitive data, zkBDI enforces true confidentiality:

🔒 End-to-end encryption – Only the recipient can decrypt
🔒 Zero-knowledge proofs – Verify without revealing details
🔒 No intermediary access – Your data stays between you and your partners

Seamless Interoperability, Works effortlessly with:

• ERPs (Odoo, SAP, Oracle, Microsoft Dynamics)
• E-invoicing & tax compliance systems
• Custom business workflows
• Legacy EDI setups

Goodbye AS2/AS4 complexity and expensive consulting setups. With zkBDI, exchanging certified data becomes a matter of calling secure APIs.

Cost & Efficiency Gains

• 80% lower processing costs vs. traditional EDI
• Near-zero rejections thanks to semantic validation
• 10x faster processing compared to manual workflows
