Introduction

What is Amazon Quantum Ledger Database?

• Amazon Quantum Ledger Database (Amazon QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a central trusted authority.

• You can use Amazon QLDB to track application data changes, and maintain a complete and verifiable history of changes over time.

• Amazon QLDB is a new class of database that helps eliminate the need to engage in the complex development effort of building your own ledger-like applications.

• QLDB, the history of changes to your data is immutable, i.e. it cannot be altered, updated, or deleted.

• QLDB uses an immutable transactional log, known as a journal. The journal is append-only and is composed of a sequenced and hash-chained set of blocks that contain your committed data.

• Ledgers are used to record a history of economic and financial activity in an organization.
