Mastering the Lightning Network. A Second Layer Blockchain Protocol for Instant Bitcoin Payments

Meer over het boek

Launched in early 2018, the Lightning Network (LN) is rapidly growing in users and capacity. This second-layer payment protocol works on top of Bitcoin and other cryptocurrencies to provide near-instantaneous transactions between two parties. With this practical guide, authors Andreas M. Antonopoulos, Olaoluwa Osuntokun, and Rene Pickhardt explain how this advancement will enable the next level of scale for Bitcoin, increasing speed and privacy while reducing fees.Ideal for developers, systems architects, investors, and entrepreneurs looking to gain a better understanding of LN, this book demonstrates why experts consider LN a critical solution to Bitcoin's scalability problem. You'll learn how LN has the potential to support far more transactions than today's financial networks, ushering in an era of global micro-transactions at sub-second resolution.In several parts, this book examines:The challenges of scaling blockchain technology and why the Lightning Network was inventedLN basics including wallets, nodes, and lightning paymentsLightning payment channels and how they workRouting payments by constructing paths of payment channels from sender to recipient, including onion routing, and atomic multi-path paymentsLightning developments such as eltoo, Schnorr signatures, HODL invoices, JIT routing, channel splicing, and channel factoriesBuilding applications on Lightning (Lapps)
