Is blockchain a distributed database?

What is a distributed ledger system?

Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time. Unlike traditional databases, distributed ledgers have no central data store or administration functionality.

How is blockchain different from distributed database?

Public blockchains are a collaborative creation, with their ultimate goal being to create a world that is completely decentralized, and where the ownership of digital assets is protected and transferable at all times. On the other hand, distributed databases are centrally managed by a service provider.

Is blockchain distributed or decentralized?
