How Blockchain Works

Blockchain is a distributed ledger technology that maintains a continuously growing list of records called blocks.

Key Components:

Block: A container for data with a unique hash
Hash: A digital fingerprint of block data
Prev Hash: Links to the previous block, creating the chain
Mining: Process of finding a valid hash (with leading zeros)
Difficulty: Determines how hard it is to find a valid hash
