Blockchain vs Database

A blockchain is a type of database that stores data in a series of blocks that are linked together in a chain. The main difference between a blockchain and a traditional database is that a blockchain is distributed, meaning that it is stored on multiple computers or nodes in a network, rather than being stored on a single central server. This makes it much harder to tamper with or hack the data stored in a blockchain, because an attacker would have to gain access to every copy of the database in the network in order to make changes. Additionally, blocks in a blockchain are usually secured using cryptography, which makes it even more difficult to alter the data stored in them.
