A Decentralized Voting System

University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

Abstract: The target of the project "A Decentralized Voting System" is to investigate whetherrecent developments in distributed systems can make a decentralized voting systemcapable of replacing the current systems in place. The current voting systems thatare taken into account are primarily democratic electoral voting systems, such asthe Swedish national electoral voting system. To remove the single central authorityconducting the vote, distributing the responsibility is the primary goal of theproject. The voting system developed relies on several trusted entities where thesystem tolerates conflict of interest to a specified degree. It is built using a softwareframework for building blockchain applications. The system is capable of managingall aspects of voting except the distribution of a digital voter card. A frontendpresents the voting stages of the application but does not offer an interface for electionadministrators. The system is verified by several criteria that apply to anyvoting system, but it is not capable of replacing a large scale election in its currentstate.Ethical aspects of digitizing and decentralizing are discussed, with particular considerationto societal and environmental impact. Voter turnout change with respect toage, privacy concerns and logistical solutions for the transition to a digitized votingsystem are also discussed.Finally, a theoretical replacement of the current Swedish electoral system with adecentralized voting system could initially exclude a social group but would reducecost and environmental impact.
