Blockchain technology is revolutionizing the way we store and transfer data. It's a decentralized ledger that records transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.
Key Concepts
- Decentralization: Unlike traditional ledgers that are controlled by a single entity, blockchain is managed by a network of computers.
- Immutability: Once data is recorded on the blockchain, it cannot be altered.
- Transparency: The blockchain is a public ledger, which means anyone can view the transactions.
- Security: Blockchain uses advanced cryptographic techniques to secure transactions.
How Does It Work?
The blockchain works by grouping transactions into blocks. Each block contains a unique code called a hash, which links it to the previous block. This creates a chain of blocks, hence the name "blockchain".
Applications
- Cryptocurrencies: Bitcoin is the most famous example of a cryptocurrency that runs on the blockchain.
- Smart Contracts: These are self-executing contracts with the terms of the agreement directly written into lines of code.
- Supply Chain Management: Blockchain can be used to track and verify the movement of goods along the supply chain.
