How does a ledger database differ from blockchain for enterprise use cases?

Ledger databases (QLDB, Immudb) are centralized, controlled by a single trusted organization, and optimized for high-throughput transactional performance. Blockchain networks (Ethereum, Hyperledger Fabric) are decentralized and consensus-based, suitable for multi-party trust scenarios without a central authority.

What compliance and regulatory use cases drive ledger database adoption?

Ledger databases are used for financial transaction history (banking, insurance), pharmaceutical supply chain (drug provenance, FDA serialization), HR employment history records, land registry and title management, and audit log immutability for SOX, GDPR, and HIPAA compliance requirements.

How do enterprises verify data integrity in a ledger database?

AWS QLDB exposes a digest API that returns a SHA-256 hash representing the state of the entire ledger at a point in time. Verification involves querying the document revision history and recomputing the hash chain. Immudb provides similar merkle tree proofs verifiable by any client without trusting the server.
