What is Azure Confidential Ledger?
Azure Confidential Ledger is a fully managed service for tamper-proof data storage. The service uses the Confidential Consortium Framework (CCF) and runs in Trusted Execution Environments (TEE) on Intel SGX hardware. Every transaction is cryptographically signed and stored in a decentralized ledger that cannot be modified by users or Microsoft.
Core Features
- Immutable data storage with cryptographic proof
- Hardware-based security through Intel SGX enclaves
- Decentralized consensus across multiple nodes
- REST API for integration into existing applications
- Audit logs with cryptographically verifiable history
Typical Use Cases
Financial institutions log transactions for compliance evidence. Healthcare organizations store audit trails for patient data access. Supply chain systems document delivery events tamper-proof.
Benefits
- Provably immutable data for audits and compliance
- Hardware security without blockchain complexity
- Managed service without custom infrastructure
- GDPR-compliant in European regions
Frequently Asked Questions
What is the difference between Confidential Ledger and blockchain?
Confidential Ledger is based on the Confidential Consortium Framework, not classical blockchain. It offers similar immutability but is faster, easier to manage, and optimized for enterprise applications.
Can Microsoft read the data in Confidential Ledger?
No, data is processed in Intel SGX enclaves. Neither Microsoft nor other parties can view the data during processing. Only authorized users with valid certificates have access.
Which compliance requirements is Confidential Ledger suitable for?
The service is suitable for requirements that demand provably immutable audit trails, such as financial regulation, healthcare data compliance (HIPAA), or supply chain documentation.
What is the performance of Confidential Ledger?
Confidential Ledger offers low latency in the millisecond range for write operations. Performance is significantly higher than classical blockchain solutions since there is no mining process.
