Introduction to the Lightning Network

Recording of a live presentation done by Brooks Boyd (@midnight426) for the Madison Blockchain meetup, introducing users to the concept of the Lightning Network. Slides for this presentation can be found at https://docs.google.com/presentation/d/10xNISNVD9PtCXiElepfmxgpIRSylFWXh27QaRaO1D20/edit?usp=sharing

Touches on topics including how the underlying bi-directional payment channels concept works, the general concepts of how on-chain scaling and off-chain scaling approaches differ, fraud proofs built into the system, and a demo of how Lightning Network transactions are intended to work (using an alpha version of the Eclair Android wallet running on the Ethereum testnet).
