Blockchain Notarization & Tamper-Proof Audit Trails for Enterprise Compliance

The Compliance Challenge: Tamper-Proof Audit Trails Without Centralized Control

Enterprise compliance requires tamper-proof records that prove "this document existed in exactly this form at exactly this time"—but traditional databases can be altered, and centralized notaries create single points of failure. Supply chain partners don't trust each other's systems, and regulatory audits demand verifiable proof of data integrity.

Blockchain notarization solves this by anchoring cryptographic hashes of documents on-chain, creating immutable timestamps that no single party can manipulate. This architecture enables Digital Product Passport compliance, supply chain provenance tracking, and regulatory audit trails—without requiring all parties to trust a central authority.

How Blockchain Notarization Works

Blockchain notarization provides tamper-proof audit trails by:

• Cryptographic Hashing: Generate a unique hash of the document (SHA-256 or similar)
• On-Chain Anchoring: Store the hash (not the document) on-chain with a timestamp
• Immutable Proof: The hash and timestamp are tamper-proof once recorded on-chain
• Verification: Anyone can verify document integrity by hashing it and comparing to the on-chain record

This architecture ensures GDPR compliance: only cryptographic hashes are stored on-chain, not personal data. Documents remain off-chain, giving enterprises control over data access and deletion.

IOTA Notarization: Enterprise Performance, Near-Zero Transaction Costs

We recommend IOTA Notarization for enterprise use cases because it provides:

• • Thousands of TPS: High-volume notarization for Digital Product Passports and supply chain tracking
• • Near-Zero Transaction Costs: Approximately 0.005 IOTA per transaction, enabling cost-effective operations at scale. Gas Station can abstract fees entirely for end users
• • Sub-Second Finality: Real-time audit trail creation for just-in-time manufacturing
• • Open Source & Auditable: Apache 2.0 license ensures transparency and regulatory compliance
• • Regulatory Alignment: Built for EU Digital Product Passport, eIDAS, and GDPR requirements
