The cost of Byzantine Fault Tolerant (BFT) storage is the main concern preventing its adoption in practice. This cost stems from the need to maintain at least 3t + 1 replicas in different storage servers in the asynchronous model, so that t Byzantine replica faults can be tolerated. In this paper, the authors present MDStore, the first fully asynchronous read/write BFT storage protocol that reduces the number of data replicas to as few as 2t + 1, maintaining 3t + 1 replicas of metadata at (possibly) different servers.
