How Blockchain Compliance Works

DataMgmt Node records every data operation as a blockchain transaction, creating tamper-proof evidence for regulatory audits.

1

Data Operation Occurs

When data is shared, accessed, or modified, the node captures the operation details including timestamp, parties, and data hash.

2

Event Encoding

The operation is encoded as a compliance event with cryptographic signatures, ensuring authenticity and integrity.

3

Blockchain Recording

The event is submitted to the configured EVM blockchain as a transaction to the zero address, permanently recording the operation.

4

Verification Available

Anyone can verify the operation occurred by checking the blockchain transaction, providing independent third-party proof.

# Record compliance event
POST /compliance/record
{
  "event_type": "data_shared",
  "data_hash": "abc123...",
  "recipient": "0x742d35Cc...",
  "timestamp": "2026-04-14T10:30:00Z"
}

# Response

  "tx_hash": "0x8f7a2b...",
  "block_number": 12345678,
  "verified": true,
  "explorer_url": "https://sepolia.etherscan.io/tx/0x8f7a2b..."
}

Supported Blockchains

Regulatory Compliance Support

Blockchain audit trails provide verifiable proof for multiple compliance frameworks.

🇪🇺

GDPR

Demonstrate lawful data processing with immutable records of consent, data access, and deletion requests. Article 30 compliance made verifiable.

  • Processing records
  • Consent tracking
  • Right to erasure proof
🏥

HIPAA

Maintain audit controls for protected health information (PHI) with cryptographic proof of access patterns and data integrity.

  • Access audit logs
  • Integrity verification
  • Breach notification proof
📊

SOX

Financial data integrity with tamper-proof records. Section 404 internal controls backed by blockchain verification.

  • Financial record integrity
  • Change tracking
  • Auditor access

Compliance API Endpoints
