AB  - Problem statement: Dealing with arbitrary failures effectively, while reaching agreement,
remains a major operational challenge in distributed transactions. In the contemporary literature, standard
protocols such as Byzantine Fault Tolerant Distributed Commit and Practical Byzantine Fault Tolerance
handles the problem to a greater extent. However, the limitation with these protocols is that they incur
increased message overhead as well as large latency. Approach: To improve the failure resiliency with
minimum execution overhead, we propose two new protocols based on proactive view change and reactive
view change. Also, both approaches have been analyzed and compared. Results: Our dynamic analysis
reflects that, in a faulty scenario, the proactive approach is computationally more efficient with reduced
latency as compared to reactive one. Conclusion/Recommendations: Moreover, unlike PBFT and
BFTDC, our agreement protocol runs in two phases, which leads to reduced message overhead and total
execution time.
