| 18:30-19:00 | FinalPay: Scalable Byzantine Fault Tolerance for Instant Payments by Laurent Bindschaedler
Abstract In this talk, I introduce a scalable, broadcast-based payment system that achieves transaction finality after a single Byzantine-consistent broadcast, combining high throughput with low-latency, asynchronous transaction finalization. Although broadcast-based systems are promising for handling high transaction volumes, existing solutions face limitations that hinder practical deployment. I will discuss solutions to critical challenges, such as resolving the risk of account lockouts through a novel asynchronous recovery mechanism and overcoming the rigidity of fixed validator sets. This approach supports dynamic validator updates, governance voting, and checkpoint creation, enhancing security and functionality. I will also propose a consensus algorithm that preserves payment finality without compromising transaction flow, designed to be safe and resilient under Byzantine conditions. | | --- | --- |
