1. Imagine a Digital Notebook Everyone Shares
Think of blockchain as a special notebook stored on thousands of computers worldwide. Everyone can see what’s written inside, but no one can erase or secretly change past pages.
2. Transactions Are Recorded in “Blocks”
When someone sends Bitcoin $BTC (or any crypto), that transaction is grouped with others into a block.
3. Blocks Are Linked Together
Once a block is full, it’s locked and connected to the previous block — like a chain of pages. This is why it’s called a block-chain.
4. Everyone Checks the Work
Before a block is added, computers on the network verify that the transactions are valid. In Bitcoin, this process is called mining (using Proof of Work).
5. No Single Owner, No Central Control
Because the notebook is copied across many computers, no single person or company can control it — making it decentralized and hard to hack.
6. Permanent and Transparent
Once something is written in the blockchain, it’s there forever, and anyone can see it.
