SRDS’21 Best Paper Award

Sep 17, 2021

We are happy to announce that our colleagues from LASIGE, at the Faculty of Sciences of the University of Lisbon, won the best paper award at SRDS’21 for a paper that they co-authored, entitled “Making Reads in BFT State Machine Replication Fast, Linearizable, and Live”. Alysson Bessani explains that they “identified a 20-year-old dormant bug on MIT’s PBFT – the most important Byzantine Fault Tolerant State Machine Replication/Consensus – which is used in several permissioned blockchains” and that they “show that the consensus-free read optimisation proposed in PBFT may lead to liveness problems”. Therefore, in this paper they also propose and evaluate a solution, which will be integrated in BFT-SMaRt. BFT-SMaRt is a Byzantine fault-tolerant state machine replication project developed and mainteined by LASIGE at the University of Lisbon, which is available on GitHub ( BFT-SMaRt is being used in VEDLIoT as a building block for the implementation of the VEDLIoT trusted membership service, a fundamental component of VEDLIoT security architecture, which requires efficient reads support.
