Lecture Abstract |
Security is a persistent issue in centralized systems. In addition, the high management cost and resource overhead (e.g., communication with the cloud or paperwork) in the centralized systems pose a bottleneck on the prosperous of Internet of Things (IoT) ecosystems. Blockchain provides a perfect solution to solve all the above-mentioned security and overhead issues lies in the centralized systems. Originally proposed as the backbone technology of Bitcoin digital currency, blockchain has become a revolutionary decentralized data management framework that will transform the way in which we share information. This talk will start from introducing the basic of blockchain technologies, including the widely used proof based (such as PoW and PoS) and voting based systems (such as PBFT and RAFT). Wireless communication systems will be proposed as an enabler of blockchain system, which will bring significant challenges and opportunities from both blockchain and wireless communications perspectives in terms of performance analysis, system design and deployment, etc. |
