Blockchain technology has awoken a lot of conversation during the last few years. Even though blockchain technology does have a lot of potential to become one of the biggest inventions of our time, it still has a lot of unresolved problems. One of the main features of the blockchain is the opportunity to cut out the use of any centralized third parties. Because blockchain technology is a distributed system in which validity is not verified by any trusted third party, the motive to achieve a consensus is formed from the vast body of blockchain users. Game theory plays a big part in the functionality of the blockchain, but it can also be used to detect the as of yet unsolved risks of blockchains. Nash Equilibrium is the most popular concept of Game theory, and in this thesis it's used to find out what motivates actors within the blockchain to make ethically sound decisions. Prisoner's dilemma is one of the most well known examples of blockchain decision-making, and it can be used in detecting the possible problems in blockchains. In this thesis it'll be discussed how the advance of blockchain technology has increased the risk for its abuse. By doing more research on the effect of Game theory on the functionality of the blockchain, the development of the blockchain can be continued in a positive direction and its security may be improved.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-02-18T07:11:50Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-02-18T07:11:50Z (GMT).
