🔗 What is Blockchain?



A blockchain is a chain of blocks where:

Each block contains data (like transactions),

Each block is linked to the one before it,

The data in a block, once added, can’t be changed.



⚙️ How It Works:

1. A transaction happens (e.g., someone sends Bitcoin).


2. The transaction is verified by computers (called nodes).


3. Once confirmed, it is added to a block.


4. That block is then linked to the previou
s block, forming a chain.
