Sammanfattning
This thesis uses blockchain technology to construct a decentralized application (often called a ‘Ðapp’) for the sake of verifying results of a matching algorithm used on data in the automotive industry. Its main intent is to explore whether the framework Ethereum can be utilized to aid in ensuring the correctness of client responses to a query sent by a peer in the network. The application was programmed in Solidity and JavaScript, and run on a local test network consisting of five clients. Testing the finished application showed that the throughput of data was slow, approximately 35 bytes/s, and that taking over the network to send corrupted information was relatively simple. These findings, along with a general study of the areas where blockchain technology is most advantageous, led to the conclusion that though it has potential as a constituent in the car industry, it is not suitable for verification of matchings at the time of writing.
