What is Blockchain?
Blockchain is a digital record system that stores data in blocks. Each block contains a list of transactions. Once a block is filled, it is linked to the previous block using a unique code called a hash. This creates a chain of blocks, which is why it is called blockchain.
Blockchain is special because it is decentralized. This means no single person or company controls it. Instead, many computers around the world verify and store the data. This makes blockchain very secure and difficult to hack.
In crypto, blockchain records every transaction of a cryptocurrency. For example, when you send Bitcoin to someone, the transaction is added to a block and then added to the blockchain. Everyone can see the transaction, but the identities are hidden.
Blockchain is not only used for crypto. It is also used for supply chain, voting systems, identity verification, and more. The biggest advantage is transparency and security.
If you want to understand crypto, learning blockchain is the first step. Blockchain is the foundation of crypto and future digital systems.
