What is Blockchain?
A blockchain is a decentralized digital ledger that records data across multiple computers in tamper-resistant "blocks." Unlike traditional databases, it:
- Stores information in chronologically linked blocks
- Operates on a distributed network (no central authority)
- Secures data through cryptographic hashing
