The College of Engineering at the University of Baghdad witnessed a public discussion for the master’s student Sajjad Hussein Faleh from the Department of Electrical Engineering, about his thesis entitled “A Proposed Consensus Algorithm for Blockchain”, on 18th Sept. 2024 in the discussion hall and under the supervision of Professor Dr. Dhiaa Jassim Kazim. The thesis aimed to create and evaluate an improved consensus mechanism known as TI-PBFT, which aims to improve performance and scalability in large-scale distributed networks. The thesis also included a study on evaluating the performance of Hyperledger Fabric in the field of vehicle registration and ownership transfer to enhance e-government services.
The thesis reached a set of recommendations, including:
- Using a mechanism that excludes low-trust nodes to enhance network security and reduce the impact of malicious nodes.
- Dividing nodes into small groups to achieve faster consensus and better network performance.
- Focusing on developing TI-PBFT to adapt to large networks, which increases the scalability of blockchain technology for wide use.
- Adopting Hyperledger Fabric to improve the efficiency of government services in vehicle registration and ownership transfer.
- Carefully selecting network settings to achieve a balance between throughput and response speed.
After the scientific discussion by the members of the discussion committee and listening to the researcher’s defense and evaluating the thesis, the researcher was awarded a Master’s degree in Electrical Engineering, specializing in Control and Computers.
