Invited Speaker

Blockchain Technologies and Services:
Challenges, Security, and Solutions

Prof. James (Jong Hyuk) Park
Department of Computer Science and Engineering,
Seoul National University of Science and Technology (SeoulTech),
South Korea

Blockchain has recently drawn much attention from interested stakeholders in a wide range of industries. The purpose behind this explosion of interest is that with the blockchain, we can operate the applications in distributed manners that could previously run through a trusted intermediary. The blockchain offers a distributed peer-to-peer network where without a trusted intermediary, untrusted individuals can interact in a verifiable manner with each other. In this talk, I will give a review of different various technologies and services based on case studies. In particular, I will point out the shortcomings and challenges of current blockchain technologies and services, and propose potential solutions considering enhanced security issues. Finally, a preliminary new service model – a blockchain based vehicle network architecture will be introduced in this talk.
