Overview:
Blockchains run on networks. With data stored and processed across the network, a blockchain eliminates the risks that centrally holding and processing data will bring. In addition, in the coming universal service of 5G, blockchains are likely to be a core element. However, the impact and needed support of networking on blockchains has been little investigated, and the current blockchain technology is far from meeting the service quality objectives of 5G, e.g., 5 ms end-to-end delay, five nines for reliability and availability, and millions of simultaneous users of the service.
Outcomes:
The objective of this PhD study is to investigate the networking impact on blockchains and vice versa. The work will be carried out in close co-operation with Project 1 to find suited mechanism and use the application oriented projects as target areas, setting context and requirements. Development of a blockchain testbed will allow experimentation on real hardware. A significant part of the work will be to establish models to assess the performance and reliability of blockchains in a realistic networking context, and to develop analytic means and/or simulators to establish their properties.
