We present an architecture and an algorithm for Byzantine faulttolerant state machine replication. Our algorithm explores the advantages of virtualization to reliably detect and tolerate faulty replicas, allowing the transformation of Byzantine faults into omission faults. Our approach reduces the total number of physical replicas from 3f+1 to 2f+1. Our(More)
