Blockchain technology has been a hot topic in recent years. But what exactly is it? Let's dive into the basics.
What is Blockchain?
A blockchain is a decentralized ledger of transactions. Each block contains a list of transactions, and each block is linked to the previous one using cryptographic hashes. This creates a chain of blocks, hence the name "blockchain."
Key Features of Blockchain
- Decentralization: Unlike traditional databases, which are controlled by a central authority, blockchain is maintained by a network of computers.
- Immutability: Once a block is added to the blockchain, it cannot be altered.
- Transparency: All transactions are visible to everyone in the network.
How Does Blockchain Work?
Here's a simplified explanation of how blockchain works:
- A transaction is created and broadcast to the network.
- Nodes in the network validate the transaction.
- Once the transaction is validated, it is added to a block.
- The block is then added to the blockchain.
Use Cases of Blockchain
- Cryptocurrencies: Bitcoin and other cryptocurrencies use blockchain technology.
- Supply Chain: Blockchain can be used to track the movement of goods and services.
- Voting Systems: Blockchain can be used to create secure and transparent voting systems.
