ContextEcho: A Benchmark for Persona Drift in Long Agentic-Coding Sessions
Xianzhong Ding, Yangyang Yu, Changwei Liu +1
A frontier language model's acknowledged "helpful programming assistant" persona does not survive long agentic-coding sessions in the deployment regime that production products act…
Optimizing Communication in Byzantine Agreement Protocols with Slim-HBBFT
Nasit S Sony, Xianzhong Ding
Byzantine agreement protocols in asynchronous networks have received renewed interest because they do not rely on network behavior to achieve termination. Conventional asynchronous…
Prioritized-MVBA: A New Approach to Design an Optimal Asynchronous Byzantine Agreement Protocol
Nasit S Sony, Xianzhong Ding
The multi-valued byzantine agreement protocol (MVBA) in the authenticated setting has been widely used as a core to design atomic broadcast and fault-tolerant state machine replica…
A Committee Based Optimal Asynchronous Byzantine Agreement Protocol W.P. 1
Nasit S Sony, Xianzhong Ding, Mukesh Singhal
Multi-valued Byzantine agreement (MVBA) protocols are essential for atomic broadcast and fault-tolerant state machine replication in asynchronous networks. Despite advances, challe…
Slim-ABC: An Optimized Atomic Broadcast Protocol
Nasit S Sony, Xianzhong Ding, Mukesh Singhal
The Byzantine Agreement (BA) problem is a fundamental challenge in distributed systems, focusing on achieving reaching an agreement among parties, some of which may behave maliciou…
