Frequently Asked Questions (FAQ) Section:
Q1: Is blockchain the same as Bitcoin?
A1: No! Blockchain is the underlying technology that makes cryptocurrencies like Bitcoin possible. Think of blockchain as the operating system (like Windows) and Bitcoin as an application that runs on it (like Microsoft Word).

Q2: Can blockchain be hacked?
A2: While incredibly difficult, it's not impossible. Hacking a blockchain would require controlling over 51% of the network's computing power, a feat that is practically unattainable for major blockchains due to the immense resources required. Its decentralized nature makes it far more secure than traditional centralized systems.

Q3: What are the main advantages of blockchain?
A3: The key advantages are decentralization (no single point of control), transparency (all participants can see the transactions), and immutability (once a record is added, it cannot be altered). This creates unprecedented trust and security.

Q4: Is blockchain only for finance?
A4: Not at all! While it started with finance, blockchain is now revolutionizing supply chains, healthcare (secure patient records), voting systems, real estate, and intellectual property rights.

Q5: What is a "smart contract"?
A5: A smart contract is a self-executing contract with the terms of the agreement directly written into code. They run on a blockchain and automatically execute when pre-determined conditions are met, removing the need for intermediaries.
