Abstract
This paper presents a hierarchical replication architec-
ture, tailored to systems that span multiple wide-area sites,
that enables free substitution of the fault tolerance method
used in each position of the hierarchy. This unique ap-
proach enables customization based on perceived risks, bal-
ancing performance and fault tolerance, by deploying ei-
ther a Byzantine or a benign fault-tolerant protocol at each
