We show that WaterBear and WaterBear-QS are efficient under both failure-free and failure scenarios, achieving comparable performance to the state-of-the-art asynchronous BFT protocols. In particular, our failure case evaluation is thus far the most comprehensive evaluation for asynchronous BFT settings.
