The Fulmo GmbH invited to the second Lightning Hackday. At this Barcamp & Hackathon one could talk about the Bitcoins Lightning Network and experience the offchain scaling in action. Almost simultaneously the team behind the COMIT Network of TenX reached an important milestone at the other end of the world.

Barcamps or unconferences are events organized by the visitors themselves

Admittedly, a topic is set, but some guest speakers can also be invited. However, the majority of the individual events are not decided until the event itself. Participants stand up and present an idea they would like to talk about. Each other can decide then, which of these topics interest them. This is the way to get together for demonstrations of beta versions, to meet in challenging discussion groups and to maintain a general exchange. Networking is an important keyword here. Isn’t it fitting that such a decentralized format was chosen for the Lightning Hackday, an event via the Lightning Network?

Fulmo GmbH is a young company which has dedicated itself 100 percent to the possibilities of the Lightning Network. In order to fulfil their role as Lightning evangelists and for networking, they created the Lightning Hackday, which went into its second round on 23 June. Unfortunately I couldn’t stop by at the first event, which is why it was especially important for me to be there. The to-do lists may get longer, deadlines more tight and sleep less, but some events still have to be attended.

The Lightning Hackday – a barcamp around the Lightning Network

And it was worth it! Beyond the course discussions that have shaped the crypto debates since the bull market last year, the focus here was on technology. The various main events, in which XUD and Lightning Labs presented individual aspects of the Lightning Network in detail, showed how large the Lightning Network complex of topics is. With Socrates I had to call οἶδα οὐκ εἰδώς : I know that I don’t know (how it would be better translated). If I thought that I would be familiar with the Lightning Network, I had to learn that a new world around Atomic multiple payments, Watchtowers, Autopilots or Splicing opens up. This large complex of topics was discussed in the mentioned lectures as well as in discussion groups. The possibilities and current limits of the Lightning Network could thus be explored.

Other developers presented their implementation of a Cross Chain Atomic Swap between Bitcoin and Litecoin. Finally, several participants, together with the Honey Roof, demonstrated in the form of a play how a transaction in the Lightning Network works.

But a hackday wouldn’t be a hackday if you didn’t make the new technology tangible and give them the opportunity to play a hand themselves. So you could experiment with several Lightning Nodes installed on a Raspberry Pi – or simply buy them for the equivalent of 20 cents via Lightning M&Ms from a Candy Dispenser. I tried the latter with Michael Mertens and Sebastian Stommel from Cryptotec – and it worked quite well despite some WLAN problems:
