During its re:Invent conference in Las Vegas today, Amazon announced its own fully managed ledger database with a central trusted authority called Amazon Quantum Ledger Database (QLDB).

The service provides customers with an append-only, fixed journal that tracks the history of all changes made to it.

Amazon also touted QLDB's other features such as its transparent nature, ease of use and speed.

Compared with existing products, the e-commerce giant's offering can execute two to three times more transactions.

AWS CEO Andy Jassy highlighted the new service's strengths, saying:

“It will be really scalable, you’ll have a much more flexible and robust set of APIs for you to make any kind of changes or adjustments to the ledger database.”
