What Is Blockchain?
Blockchain is a distributed ledger technology that enables secure, transparent, and tamper-proof record-keeping. Unlike traditional databases, blockchain stores information across a network of computers — making it decentralized and highly resistant to modification.
How Blockchain Works
Transactions are grouped into blocks and added to a chain in chronological order. Each block contains:
- A cryptographic hash of the previous block
- A timestamp of when the block was created
- The transaction data itself
