Breaking Fault Lines: Unifying TEE-Assisted BFT Consensus in Partially Trusted Worlds

This paper revisits TEE-assisted BFT under a universal partial-TEE model, where an arbitrary subset of replicas execute inside TEEs while the remaining replicas operate without hardware trust guarantees. We show that heterogeneous trust changes the structure of quorum formation and fault tolerance. In particular, we de...
