Christian Decker from Blockstream and the DLT staff from MainbornWolff will give us an introduction and deep-dive into the Lightning Network.

How should an internet-native money and cash look like? How to make it scale while remaining decentralized? How to achieve the capacity required to serve the daily transaction needs not only of every human on this planet, but also of the machines and automated processes of the future; that is, millions of transactions per second world-wide, with near-zero fees?

The Bitcoin community has been debating (to say the least) for the last 3 years, and even most of the harshest critics of the "small blockers" don't deny in principle that a so-called layer 2 is inevitable.

A blockchain fundamentally doesn't scale. It must run redundantly on thousands of computers world-wide in order to remain truly immutable and incorruptible. To chisel every single payment for a coffee into such a ledger system is thus far too heavy on resources.

Enter the Lightning Network. Turns out there is a way that Alice can be paid by Bob for a coffee without having to tell the world, while still being safe from double spending. How does that work? Tonight we will learn all about the clever solution that has been found for this problem.

Target Audience: We will have two parts. First we will address a general audience, later we will dive deeper into the matter, demonstrating how to set up and run a lightning node. We will probably also have an extended Q&A and discussion panel to talk about the future of scalability in blockchains, layer 2 solutions, the challenges, and potential further applications therein.

Our speakers tonight include:

Christian Decker, long-time researcher and developer for the Bitcoin Core protocol and layer 2 solutions, wrote the world's first PhD thesis that was entirely on Bitcoin in 2012 at the ETH Zurich Distributed Computing group, currently employed at Blockstream.


Dirk Röder from the DLT department at MaibornWolff. Consultant, trainer, and speaker.


Florian Maier, software architect at MaibornWolff, crypto-currency enthusiast and expert.



Diethelm Baumann, Lawyer
