In this video, we break down Chapter 8 of Grokking Bitcoin by Kalle Rosenbaum in a simple and beginner-friendly way. Learn how Bitcoin removes central authority by using a powerful peer-to-peer (P2P) network.
We’ll explore how the gossip network works, how nodes communicate using messages like inv, getdata, and block, and how transactions spread across the network in seconds. You’ll also understand how new users join the Bitcoin network (bootstrapping), and why lightweight wallets rely on bloom filters and merkle proofs.
Whether you're new to blockchain or trying to strengthen your fundamentals, this video will give you a clear understanding of how Bitcoin stays decentralized, secure, and censorship-resistant.
