What Is Blockchain?

A blockchain is a decentralized ledger recording transactions across a network of computers. Each block contains data, a timestamp, and a cryptographic hash, linked to the previous block, ensuring immutability. Bitcoin and Ethereum use blockchain for secure, transparent transactions.

How Blockchain Works

Nodes: Computers validate and store data.

Consensus: Proof of Work (PoW) or Proof of Stake (PoS) ensures agreement.

Immutability: Once recorded, data can’t be altered.

In 2024, 10,000+ blockchains existed, per Statista.

Why Blockchain Matters in 2025

Transparency: Public ledgers show all transactions.

Security: Cryptography prevents tampering.

Decentralization: No central authority, reducing risks.

Global blockchain spending hit $12 billion in 2024, per IDC.

Use Cases

Finance: DeFi platforms like Uniswap processed $1 trillion in 2024.

Gaming: Blockchain games like Axie Infinity tokenize assets.

Supply Chain: IBM’s Food Trust tracks goods, cutting fraud by 30%.

Healthcare: Patient records on blockchain enhance privacy.
