What Is Blockchain Technology?
Blockchain is the foundation of digital currencies like Bitcoin and Ethereum—but its potential goes far beyond cryptocurrencies. At its core, a blockchain is a decentralized digital ledger that records transactions in a secure, transparent, and tamper-proof way.
Unlike traditional systems where a central authority (like a bank or a government) keeps track of your data, blockchain relies on a network of computers (called nodes) that work together to validate and record information. This makes the system trustless—meaning you don’t need to trust a single party, but instead the technology itself.
How Blockchain Works
- Transactions Initiated: When someone sends cryptocurrency, that transaction is broadcast to a network of nodes.
- Validation: These nodes use complex algorithms to validate the transaction, making sure the sender has enough balance and isn't trying to double-spend.
- Block Creation: Validated transactions are grouped together in a "block."
- Chain Linking: Each block contains a unique code called a hash, and it also carries the hash of the previous block. This creates a chain—hence the name blockchain.
- Immutability: Once added, a block cannot be altered without changing every block after it, which would require majority control of the entire network. This makes blockchain virtually tamper-proof.
Key Features of Blockchain
- Decentralization: No single point of control. The network is spread across many computers worldwide.
- Transparency: Every transaction can be publicly verified on the blockchain.
- Security: Cryptographic algorithms ensure the integrity and privacy of the data.
- Immutability: Once recorded, data cannot be changed—providing a reliable source of truth.
- Smart Contracts: Self-executing contracts that automatically run when specific conditions are met, enabling more than just currency—like decentralized apps (dApps).
