In "Blockchain enabled embedded systems for IoT" thesis the goal was to research and implement a way of storing data generated by IoT embedded devices using blockchain technology. The introductory part of the paper consists of an overview of the basic architecture of an IoT device with security challenges and threats it currently faces. The following part describes three IoT platforms that were taken into consideration when choosing a build platform, the Google Cloud IoT platform, Amazon Web Services, and the Kaa open source platform. At the end of the IoT section, some of the basic communication protocols which play a key role in the bright future of the Internet of Things are mentioned and described in more detail. The next part of the thesis consisted of studying the basic cryptography security methods that enable blockchain technology - hash functions, symmetric and asymmetric encryption, and digital signature. The blockchain section contains a theoretical basics of the blockchain technology architecture, that is, the structure of the chain, block and other relevant parameters, as well as a description of the three public blockchains used to build the applications and store the hashes of data - Bitcoin, Ethereum and Stellar. The last section of the paper describes in detail and shows all the steps taken in the of making the applications. The first phase consists of registering the embedded device on the Google Cloud IoT platform and configuring all the necessary Google Cloud tools in order to make data upload and storage possible. After registering the device, the steps of creating applications are given for all three public blockchains using the appropriate Python libraries, with the cost estimates of such storage methods given at the end.
