Day 2: How Bitcoin Gets Secure – The Role of Mining

Security isn’t just magic—it’s math and machines.

1. Proof of Work (PoW): Miners solve puzzles to earn the right to add blocks.

2. Difficulty Adjustment: The network self-adjusts to stay consistent (a block every ~10 minutes).

3. Hashing: Miners create a unique digital fingerprint for each block.

4. Block Reward: Bitcoin is the prize for securing the network.

5. Energy = Security: The more miners, the harder to attack.
