What is Blockchain?
Blockchain technology is a digital ledger that allows data to be stored globally on thousands of servers. It lets participants in a network verify transactions independently, without the need for a central authority. This ensures security and transparency in transactions.
How Does Blockchain Work?
At its core, blockchain is a chain of blocks, where each block contains a number of transactions. Every time a new transaction occurs, it is recorded into a block. Once a block is filled with transactions, it is added to the chain in a linear, chronological order.
Key Features of Blockchain
- Decentralization: Unlike traditional ledgers, blockchain does not rely on a central point of control.
- Transparency: All transactions are visible to anyone within the network.
- Immutability: Once recorded, the data in any given block cannot be altered without altering all subsequent blocks.
Benefits of Blockchain Technology
Blockchain offers numerous benefits across various sectors. Here are some of the most significant advantages:
- Enhanced Security: Blockchain's decentralized nature and cryptographic algorithms make it highly secure.
- Reduced Costs: By eliminating intermediaries, blockchain reduces transaction costs.
- Increased Efficiency: Transactions are faster and more efficient, as they do not require manual processing.
Blockchain in Cryptocurrency
Blockchain is the backbone of cryptocurrencies like Bitcoin and Ethereum. It enables secure and anonymous transactions, making it ideal for digital currencies.
