Does Blockchain use database?

Blockchain Database does exist. A blockchain is kind of a database because it is a digital ledger that stores information in data structures called blocks. On the other hand, a traditional database is a data structure used for storing information.

What is the difference between Blockchain and database?

A blockchain is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. … Database uses centralized storage of data. Blockchain uses decentralized storage of data.

How does a Blockchain database work?

In Bitcoin, a blockchain is an immutable digital public ledger that is a continuously growing distributed database that is cryptographically secured. A blockchain stores information in uniform sized blocks. Each block contains the hashed information from the previous block to provide cryptographic security.
