Blockchain
Definition
A shared digital ledger where transactions are recorded in linked blocks and verified by a network.
In Plain English
A blockchain is like a public notebook where everyone can check the history, but changing old pages is extremely difficult.
Real-World Example
A company might use a blockchain to record token ownership or verify a transaction history without relying on one private database.
Why It Matters for Your Work
Blockchain is the foundation for crypto assets, smart contracts, NFTs, and many Web3 systems.
Common Mistake
Assuming blockchain is automatically better than a normal database. Most business workflows do not need public, irreversible transactions.
