## Description

Patrick McCorry's hands-on workshop about off-chain protocols. He covers the payment channels, the lightning network (HTLC + routing), the problems around payment channel hubs and an introduction to commitchains (plasma/rollup). Plenty of audience interaction that helps explain the concepts.
