1. What is a blockchain?

A blockchain is a digital chain of blocks in which transactions are stored. Each new set of transactions is added to the chain and can no longer be changed.

2. Why does blockchain exist?

Blockchain was developed to enable digital transactions without an intermediary (such as a bank). The goal is to create trust through technology rather than through a central authority.

3. Why is it called “blockchain”?

Because information is stored in blocks that are linked together in a chain.

4. What is inside such a block?

A block contains: a list of transactions, a timestamp & a reference (hash) to the previous block.

5. What is a hash?

A hash is a unique digital code calculated based on data. If anything changes in the data, the hash changes as well.

6. Why is blockchain secure?

Because any change in a block would invalidate all subsequent blocks. You would have to hack the entire network to change anything.

7. Who controls a blockchain?

No one and everyone. The network is managed by thousands of computers (nodes) worldwide.

8. What is a node?

A node is a computer that stores a copy of the blockchain and helps verify transactions.

9. What does “decentralization” mean?

That there is no central boss or server. The power is distributed across the network.

10. What is the difference between a traditional database and a blockchain?

A traditional database: Has one owner & Can be modified.

Blockchain: Has no central owner & Is virtually immutable.

📘 BLOCK 2 – What is Bitcoin?

11. What is Bitcoin?

Bitcoin is a digital currency that operates on blockchain technology.

13. Why was Bitcoin created?

As an alternative to banks and governments, especially after the financial crisis of 2008.

14. How many Bitcoins exist?

There will be a maximum of 21 million Bitcoins. In the beginning, 50 Bitcoins were released per block on the blockchain. Approximately every 4 years (every 210,000 blocks), this amount is halved. This is pre-programmed in the protocol and can only be changed if a majority of the network agrees to modify the software.

15. What is mining?

Mining is the process by which new blocks are added to the blockchain and new Bitcoins are created.

16. Why does mining consume energy?

Because computers perform complex mathematical calculations to verify transactions.

17. What does “Proof of Work” mean?

A system in which miners prove they have used computational power to add a block.

18. Is Bitcoin anonymous?

Not completely. All transactions are publicly visible, but without names, only wallet addresses.

39. What is a hardware wallet?

40. What does “Not your keys, not your coins” mean?

If you do not own your private keys, you do not truly own your crypto.
