How Does Blockchain Work?

A blockchain is a distributed digital ledger that records transactions across a network of computers. Each block contains a batch of validated transactions linked cryptographically to the previous block.

Core Concepts

Blocks: Containers holding transaction data plus a unique identifier (hash).
Chain: Each block references the previous block's hash, forming an unbreakable sequence.
Consensus: Network participants agree on the valid chain through mechanisms like Proof of Work or Proof of Stake.
Immutability: Altering any block would invalidate all subsequent blocks, making tampering detectable.
