Bitcoin is a digital currency, just like how you have physical money like coins and notes. But instead of existing in a physical form, Bitcoin exists only in the digital world. It's a type of money that you can use to buy things or send to other people electronically.
Now, let's talk about the blockchain. Imagine a big notebook or a ledger that keeps track of all the transactions made with Bitcoin. This notebook is not owned or controlled by any single person or organization. Instead, it is maintained by a network of computers all around the world. This network is called the blockchain.
Every time a Bitcoin transaction happens, it is recorded in this notebook, which is a block. But here's the interesting part: each new block is linked to the previous block, forming a chain of blocks, hence the name "blockchain." This chain of blocks creates a permanent and unchangeable record of all the transactions that have ever taken place with Bitcoin.
Because the blockchain is maintained by many computers, it is highly secure and difficult to tamper with. This means that once a transaction is recorded on the blockchain, it becomes very difficult to alter or reverse it. This security and transparency are some of the key features that make Bitcoin and blockchain special.
So, in simple terms, Bitcoin is a digital currency, and the blockchain is a decentralized ledger that keeps track of all Bitcoin transactions in a secure and transparent way.
