The devil hides in the model: Reviewing Blockchain and BFT protocols

Abstract

Recent advances in blockchains and Byzantine Fault Tolerant protocols have been numerous and varied in nature. However, making a fair and consistent comparison of existing protocols is a difficult task that must begin right at the execution model. In this work, we undergo a review of several prominent blockchain protocols including their models, i.e., network synchrony, cryptographic assumptions, corruption, as well as latency and communication cost figures. This review illustrates the issues that can arise due to the lack of standardization on blockchain terminology. For example, we show that in two prominent blockchain protocols, seemingly minor technical details in the formulation leads to the execution model being strictly different from the intended one.
