Today it's all about the Lightning Network again! Tankred Hase from Lightning Labs will introduce and demo "Lightning App", a cross-platform wallet software for desktops, and Rene Pickhardt will deliver an in-depth explanation of the mechanics of the Lightning Network at the protocol level as well as some prospects about near-future features like splicing.

Target Audience: The first part also might appeal to a general tech, dev, opsec or app design audience, the second part presumes knowledge about Bitcoin and basics about Lightning.

Tankred Hase is the Lead Application Engineer at Lightning Labs. Previously he co-founded a startup that worked on making email encryption easier to use. Since then he's been active in maintaining OpenPGP.js, the encryption library behind many webmail encryption products, built a PGP key server for automatic public key discovery, and generally loves tackling challenges around the usability of cryptography.


Rene Pickhardt is a self employed Data Science Consultant and LN hacker/enthusiast currently working on the Autopilot feature of lnd and trying to help drafting the Splicing protocol definition of BOLT 1.1.

18:45 Welcome from your hosts

19:00 Tankred Hase: Lightning App

The Lightning Network is a layer 2 scaling solution for Bitcoin. In this talk we'll take a look at the Lightning App, a cross-platform wallet being developed at Lightning Labs, which aims to hide the technical complexities of the Lightning protocol by providing a consumer grade user experience. After a short demo of the user interface, we’ll give an overview of the architecture, dive deeper into threat modeling, and finish with a discussion on application security.

20:15 Break

20:30 Rene Pickhardt: The Mechanics of the Lightning Network

We review some of the technical details of the current protocol definition for payment channels within the Lightning Network protocol, and look at the concept of hashed time locked contracts to add routing to the network of payment channels. It will be emphasized how the LN, even though being an overlay layer for blockchain technologies, is just a creative use of the Bitcoin protocol. Finally an outlook and conceptual idea about the future features like Atomic Multipath Routing, Splicing, Watchtowers and Atomic Swaps to be included in Basics Of Lightning Technologies 1.1. (BOLT 1.1) will be given.

21:30 Q&As

22:00 End of official part

The talks and discussions will be recorded and probably streamed.

We'll be hosted in Blockchain Consulting's new hub near the Hackerbrücke! Food and drinks will be provided for! Thanks very much folks!
