Verifiability Extensions and Improvements of Blockchain-based E-Voting

State: completed by CSM

Digitization of electronic voting systems is critically discussed around the globe. Often, Electronic Voting (E-Voting) system architectures are centralized and intransparent for voters. In contrast, a blockchain-based E-Voting system can offer transparency and auditability for every voter [1]. The CSG has developed a BC-based electronic voting system [2]. The goal of this thesis is to extend the Rust blockchain implemented in [3] in order to (i) improve notion of Recorded-as-Cast (ii) implement counted-as-recorded verifiability and (iii) implement a front-end application for both the voter and the authorities. Also, this work should include a thorough evaluation of the improvements to the prior architecture.
