Abstract [en]

Blockchain seems to be the hot new innovation that brings disruption to many different industries in the form of decentralization. Groups of peers can finally organize and work together without a central actor having an authority over the transactions that occur. Other than decentralization, due to the distributed and cryptographic nature of the data, the system also enjoys resilience, immutability and safety. In this thesis, we are leveraging permissioned blockchain technology to take steps towards a trustless service level agreement (SLA) management system where both service providers and customers lack the power to tamper with the contracts and their outcomes. The thesis yields a systematic literature review on the state-of-the-art within SLA management and relevant blockchain technology, a proof-of-concept working with Ericssons decentralized edge service marketplace, Nubo, and finally asimulation which evaluates how the proof-of-concept performs in terms of throughput and latency under different network loads. The simulation shows that the network works as expected, until 70 transactions per second (TPS) are reached, at which point the network is limited by throughput.

Abstract [sv]

Blockchain ser ut att vara den nya teknologin som leder till stora förändringar i olika industrier i form av decentralisering. En grupp av noder kan till slut organisera sig och arbeta tillsammmans utan en central figur som styr och har kontroll över arbetet. Utöver decentralisering ger blockchain också fördelen av uthållighet, oföränderlighet och säkerhet till systemet tack vare sin kryptografiska grund. I den här studien utnyttjar vi privat blockchainteknologi för att ta steg mot en decentraliserad service level agreement (SLA) platform, där både tjänsteleverantörer och konsumenter saknar makten att manipulera kontrakt och dess resultat. Studien ger en systematisk literaturstudie på state-of-the-art inom SLA och relevant blockchain teknologi, ett bevis på koncept som fungerar tillsammans med Ericssons decentraliserade Nubo Service Marknad, och till slut en simulation som undersöker hur systemet reagerar i form av genomströmmning och responstid under olika nätverksbelastningar. Undersökningen visar att nätverket fungerar som förväntat upp till 70 transaktioner per sekund, då nätverket begränsas av genomströmning och köer bildas.
