Annex 2: Exam preparation

The blockchain is considered as the most disruptive innovation since the Web.

Read the sections 1 and 2 in this article : Christidis and M. Devetsikiotis, ‘‘Blockchains and smart contracts for the Internet of Things,’’ IEEE Access , vol. 4, pp. 2292–2303, 2016. https://mycourses.aalto.fi/pluginfile.php/378344/mod_resource/content/1/Christidis%20and%20Devetsikiotis.pdf

One part of the exam will be a dissertation with regard to the impact of the Blockchain (especially permissioned blockchains) and Smart Contracts on the service ecosystem (OpenAPI, microservices, SLA ...).
