What is a Blockchain Node?​

A blockchain node is a crucial component of any blockchain network. It is a device, such as a computer or a server, that runs blockchain client software and connects to the network. Nodes help maintain the security, stability, and decentralization of a blockchain by performing key functions.

Blockchain technology has gained significant popularity, particularly after the success of Bitcoin. Many people believe that blockchain is merely a distributed ledger or database, but this is a misconception. Blockchain is much more than just a decentralized database; it is a unique data structure designed to solve critical issues in digital transactions, particularly in cryptocurrency.

To understand the importance of blockchain, let's explore its necessity through a short story.
