Dissecting the Performance of Chained-BFT
[article]
2021
arXiv
pre-print
Preserved Fulltext
A new paradigm, combined with decades of research in BFT SMR and blockchain (namely chained-BFT, or cBFT), has emerged for directly constructing blockchain protocols. ...
To validate Bamboo, we introduce an analytic model using queuing theory which also offers a back-of-the-envelope guide for dissecting these protocols. ...
To dissect and explain the performance of chained-BFT variants, we propose a novel framework called Bamboo. ...
