Location
Type: talk
Duration: 45m

Watch recording

Join us for a comprehensive discussion on nix-bitcoin, a powerful collection of Nix packages and NixOS modules that allows the easy installation of feature-rich Bitcoin nodes with a focus on security. Learn how it serves a wide array of applications, from personal wallets to Bitcoin infrastructure and backend applications, enabling security and privacy by default. We'll also explore how nix-bitcoin leverages the benefits of the Nix ecosystem to offer robust security, a potent testing framework, and customization capabilities to its users. Additionally, we will discuss the unique service isolation feature, the strengths, and the challenges that need to be addressed.

Ecash in the wild

Calle

Time: Fri, Oct 6 · 2:30 PM – 3:00 PM
Location
Type: talk
Duration: 30m

Watch recording

Chaumian ecash is now part of the Bitcoin ecosystem which has sparked renewed interest on this almost ancient technology and how it can be used to build the future of permissionless online payment systems. Today, ecash is often seen as a way of making custodial Bitcoin wallets that give users a tremendous level of privacy. However, as I will outline in this talk, the specific properties of ecash enable a new breed of payment systems that were previously not possible to build. These can range from web components for privacy-preserving paywalls or paid online services, to bearer ecash tokens wrapped into various messaging protocols, to new designs for Bitcoin mining pool payouts that remove the link between the miner and their earned rewards. All of these require a basic infrastructure such as Cashu mints and wallets that process ecash user transactions inside the system, as well as their payments from and to the broader Bitcoin Lightning network. As the context in which ecash is used becomes more diverse and specific to each application, Nix becomes ever more relevant for deploying Cashu in the wild.

Solving the "It works on my machine" Problem!

Peter Neuroth

Type: talk
Duration: 40m

Watch recording

Every developer has heard these frustrating words before. The struggle to maintain consistency across development environments in collaborative setups is a universal challenge. In this talk, we'll explore how to conquer this challenge using nix-shell — a powerful tool that can reshape how we manage and share development environments. The presentation step through the practical steps of setting up a flake.nix for a nix-shell that we can not only use for local development but also for CI/CD pipelines. We'll discuss how nix-shell stacks up against Docker as an alternative solution. Get ready to say goodbye to the "It works on my machine" conundrum and join a world of "It works on every machine".

NixOS Modules: How to run your apps on NixOS

0xB10C

Time: Sat, Oct 7 · 10:00 AM – 11:30 AM
Location
Type: workshop
Duration: 1h 30m

Watch recording

NixOS has a modular system for declarative configuration. This system combines multiple modules to produce the full system configuration. One module could define configuration options for your YOUR_APP telling NixOS how and when to run it. This workshop is for beginners who haven't yet written their own NixOS modules but are already somewhat familiar with Nix and NixOS. The workshop consists of a presentation and a hands-on part where participants will learn to write NixOS modules. System requirements and setup instructions will be provided beforehand. We'll cover the imports-options-config trio, referencing configuration options from other modules, systemd services (simple and oneshot), systemd timers, built-in functions that NixOS provides us, and more.
