**Step 2: How Bitcoin Works**

Bitcoin operates on a technology called **blockchain**. A blockchain is a public, distributed ledger that records all Bitcoin transactions.

Here’s how it works:

1.**Transaction initiation occurs when a user sends a Bitcoin transaction request to the decentralized network for verification and processing. 2. **Verification**: Miners verify the sender balance and that the transaction is valid.
3. **Block Creation**: Verified transactions are bundled into a “block” by miners.
4. **Mining**: Miners solve complex mathematical puzzles. The first to solve it adds the block to the blockchain and is rewarded with new Bitcoins.
5. **Finalization**: The transaction is confirmed and recorded permanently on the blockchain.

**Step 3: Getting Started with Bitcoin**

* When a miner solves the puzzle , they’re rewarded .
* The miner is rewarded with newly minted Bitcoin.

Mining requires significant investment in hardware and electricity. Today, it’s dominated by large mining farms with specialized equipment (ASICs).

**Step 7: Legal and Regulatory Considerations*
