Abstract [en]

The blockchain technology constitutes a domain where significant research is done. The technology revolutionized the world through the cryptocurrency Bitcoin, and since then new applications of the technology have emerged. One of the applications is to represent real assets as digital assets on a blockchain, so called smart-property. In this thesis a smart-property solution is utilized to address creditworthiness issues within the transport industry. A Proof-of-Concept (PoC) is implemented using smart-property through colored coins on Bitcoin’s blockchain. To conclude the usefulness of the solution, two alternative solutions are proposed for comparisons. Requirements for a solution to the problem are specified, and the solutions are evaluated against them. Thus the thesis investigates and compares the solutions’ abilities to address the creditworthiness problem motivating the thesis. The evaluation aspects constitute of: confidentiality, integrity, availability, consistency, immutability, response time, cost, customer usefulness, trust and environmental issues. It is concluded that a smart-property solution is adequate for the problem. The solution however got inadequacies, mainly regarding confidentiality, but that is concluded not to affect the problem domain.

Abstract [sv]

Blockchainteknologin utgör ett område där mycket forskning utförs. Teknologin revolutionerade världen genom kryptovalutan Bitcoin, och sedan dess har nya applikationer av teknologin växt fram. En av applikationerna är att representera verkliga tillgångar som digitala tillgångar på en blockchain, så kallad smart-property. I denna uppsats används smart-property för att lösa kreditvärdighetsproblem som finns inom transportindustrin. En implementation för att påvisa konceptets ändamålsenlighet utförs där smart-property används genom colored coins på Bitcoins blockchain. För att kunna bedöma användbarheten hos lösningen, föreslås även två alternativa lösningar för jämförelse. Krav för en lösning på problemet specificeras i uppsatsen och lösningarna evalueras mot dessa. Alltså undersöker och jämför denna uppsats lösningarnas förmåga att lösa kreditvärdighetsproblemet som motiverar denna uppsats. Aspekterna för evaluering utgörs av: konfidentialitet, integritet, tillgänglighet, konsistens, oförändlighet, responstid, kundnytta, pålitlighet och miljöpåverkan. Slutsatsen som dras är att en lösning baserad på smart-property är adekvat för problemet. Lösningen har dock brister, främst vad gäller konfidentialitet, som däremot inte påverkar problemdomänen.
