What is Blockchain? Blockchain is a distributed database that is shared among the nodes of a computer network. In layman's words, Blockchain connects everything to everything through connected nodes of a computer network. Inside each node, a piece of information is stored in digital format. If you know about cryptocurrency, you must know about what blockchain really is. If you don't know that all cryptocurrencies like Bitcoin are made up of blockchain technology, you might not know that everything you invest in cryptocurrencies, its data is stored on the same blockchain nodes in the network. Blockchain technology is fundamentally so secure that a single person cannot tamper with the records of data but can access to read the data without the need for a trusted third party.

How does a Blockchain Work

The main purpose of blockchain is to allow developers to record and distribute digital data without getting edited. The foundation of blockchain is set for immutable ledgers, or records of transactions that are impossible to alter, delete, or destroy. That's why blockchains are also known as distributed ledger technology (DLT). It was first proposed as a research project in 1991, which is later predated its first widespread application in use: Bitcoin, in 2009. During these years, blockchain has exploded through the creation of various cryptocurrencies, decentralized finance (DeFi) applications, non-fungible tokens (NFTs), and smart contracts.
