FAQ Section

Q1: What makes Bitcoin a decentralized system?
A1: Bitcoin eliminates central authorities by using a peer-to-peer network and consensus algorithms like Proof-of-Work (PoW).

Q2: How does blockchain prevent double-spending?
A2: Transactions are validated by miners and recorded on an immutable ledger, making fraud computationally impractical.

Q3: What are the real-world applications of blockchain beyond cryptocurrencies?
A3: 👉 Explore blockchain’s use in supply chains, healthcare, and voting systems.

Q4: Why is Nakamoto consensus significant?
A4: It introduced a trustless mechanism for achieving agreement in open networks, revolutionizing digital transactions.

Q5: What are the risks of using cryptocurrencies?
A5: Volatility, regulatory uncertainty, and security breaches 👉 demand cautious adoption.
