Part 2
In this post, we will explain blockchain in a simple way as if we are telling a story.

Blockchain means "Chain of Blocks"
You can imagine it as a digital ledger, but instead of being in one place at a bank, it is present at thousands or millions of devices around the world.

How does it work?
1. Transactions
Whenever someone sends Bitcoin to another person, this process is recorded as information:
"Someone sent 0.5 $BTC to someone
2. Grouping into a Block
A collection of these transactions is gathered into a single file called a "Block".
3. Adding the Block to the Chain
The new block is linked to the previous block, and thus it becomes a chain… Chain of Blocks = Blockchain.
4. Security and Encryption
Each block is linked to the one before it through encryption codes, so if someone tries to change information in an old block, they have to change everything that comes after it — and this is nearly impossible because the entire network will expose them.

Main Features
Transparency: Anyone can see all transactions.
Immutability: You cannot delete or modify a completed transaction.
Security: It is very difficult to hack or forge.

You can say that Bitcoin$BTC lives and moves within the blockchain network, which keeps its records and secures it.
I hope the explanation is simple and clear for everyone..
