Preface
The Lightning Network (LN) is a second layer peer-to-peer network that allows us to make Bitcoin payments “off-chain,” meaning without committing them as transactions to the Bitcoin blockchain.
The Lightning Network gives us Bitcoin payments that are secure, cheap, fast, and much more private, even for very small payments.
Building on the idea of payment channels, first proposed by Bitcoin’s inventor Satoshi Nakamoto, the Lightning Network is a routed network of payment channels where payments “hop” across a path of payment channels from the sender to the recipient.
The initial idea of the Lightning Network was proposed in 2015 in the groundbreaking paper “The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments,” by Joseph Poon and Thaddeus Dryja. By 2017, there was a “test” Lightning Network running on the internet, as different groups built compatible implementations and coordinated to set some interoperability standards. In 2018, the Lightning Network went “live” and payments started flowing.
In 2019, Andreas M. Antonopoulos, Olaoluwa Osuntokun, and René Pickhardt agreed to collaborate to write this book. It appears we have been successful!
