Asynchrony-Resilient Sleepy Total-Order Broadcast Protocols
Francesco D’Amato, Giuliano Losa, Luca Zanolini · 2024
Dynamically available total-order broadcast (TOB) protocols tolerate fluctuating participation, e.g., as high as 99% of their participants going offline, which is especially useful in permissionless blockchain environments. However, dynamically available TOB protocols are synchronous protocols, and they lose their safety guarantees during periods of asynchrony. This is a major issue in practice.
