Content
NB! This is an elective course and may be cancelled if fewer than 10 students are enrolled by August 20th.
The first part of the course covers fundamental technology behind blockchains, including proof of work and proof of stake consensus mechanisms. We also cover different models, including permissioned and permissionless deployment.
The second part covers smart-contract programming, security of smart contracts and applications. This part will also cover payment channels and similar technology.
The third part focuses on different applications for blockchain technology. Among others, self-sovereign identity and decentralized storage applications are discussed. This part also discusses how blockchain technology may contribute to or threaten UN sustainability goals.
In the lab students work on simulations to better understand the technology and learn to implement a secure application using smart contracts. Additionally some lab sessions are discussion on different application scenarios.

Coursework requirements
There are two mandatory activities, that must be approved before students can participate in the exam.
- Students have to complete lab assignments and simulations. This can either be done during lab hours, or at home, with successive approval.
- Students need to contribute to discussion on application areas, either through active participation during lab hours, or through the presentation of a review article on one application area.
