Alea-BFT: Practical Asynchronous Byzantine Fault Tolerance
Traditional Byzantine Fault Tolerance (BFT) state machine replication protocols assume a partial synchrony model, leading to a design where a leader replica drives the protocol and is replaced after a timeout. Recently, we witnessed a surge of asynchronous BFT protocols, which use randomization to remove the need for bounds on message delivery times ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Optimized Consensus for Blockchain in Internet of Things Networks via Reinforcement Learning
Most blockchain systems currently adopt resource-consuming protocols to achieve consensus between miners; for example, the Proof-of-Work (PoW) and Practical Byzantine Fault Tolerant (PBFT) schemes, which have a high consumption of computing/communication

Teaching Theology and Law in the Australian Secular Law School: Lessons From the Adelaide Law School
ABSTRACT The Adelaide Law School introduced Law and Religion into its suite of elective courses in 2012, the culmination of a long process of encouraging both the institution and individual faculty members to accept that this sub‐discipline, at the time already well‐recognized in the United States and Europe, properly belonged as a scholarly pursuit in
