Rui Gomes of OpenNode directs a workshop dedicated to spinning up a message-board powered by Bitcoin’s Lightning network.

Over the course of 45 minutes, Gomes builds a messaging hub that is able to rebroadcast directly onto Twitter, while answering questions from the audience.

The lightning network, simply put, is a network of payment channels aiming to solve Bitcoin’s “scalability problem,” or its inability to process transactions en masse, he said. None of these transactions are hitting the mainchain, though they do eventually resolve there.
