Scaling Lightning
Scaling Lightning: Running a lightning node is essentially plug and play. Self-sovereign bitcoin and lightning payments have never been easier. So why are blocks so empty? Is this evidence of the lightning network working as intended? Or is the network growth limited by technical, UX, and social challenges?

Panel: Building your privacy stack
Ecash: New Frontiers in Privacy
Ecash can improve privacy and connectivity. Is it worth the loss of control of custody?
The second renaissance of ecash
The revival of ecash is unlocking a new frontier for digital payments, driving innovation across the Bitcoin ecosystem. In this talk, I will explore the pioneering work being done by developers building applications with this technology. We will examine the cryptosystem behind the Cashu protocol and discuss potential improvements, paving the way for more advanced Chaumian ecash systems in the future.
Ecash in the wild
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.
