Stabl: The Sensitivity of Blockchains to Failures
Vincent Gramoli, Rachid Guerraoui, Andrei Lebedev, Gauthier Voron · 2025
Blockchains promise to make online services more fault tolerant because they are replicated on a distributed system of nodes. Their nodes typically run different implementations of the same protocol across different geo-distributed regions, making the protocol supposedly tolerant to various failures including isolated crashes, transient failures, network partitions or attacks. Unfortunately, their fault tolerance has never been compared.
