1. 1. Blockchain-based e-voting system without digital ID: A Proof-of-Concept

   Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Författare :Leonard Schick; [2024]
   Nyckelord :Computer science; Cryptography; Crypto; Blockchain; Distributed systems; e-voting; electronic voting; Ethereum; Hyperledger; Hyperledger besu; Decentralization; Datavetenskap; Kryptografi; Blockkedja; Distribuerade system; e-röstning; Elektronisk röstning; Blinda signaturer; Ethereum; Hyperledger Besu; Decentralisering;

   Sammanfattning : Electronic voting systems have the potential to offer a cost effective, secure and transparent way of communicating with the citizens, increasing trust and participation. However creating a secure open source electronic voting system providing confidentiality and transparency with sufficient performance has long been a challenge. LÄS MER

3. 2. Smart Contract Maturity Model

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Jordy Jordanus Cornelius van Raalte; [2023]
   Nyckelord :smart contracts; maturity models; smart contract problems; blockchain; proof of work; proof of stake; smart contract implementation problems; smart contract use cases; smart contract challenges; smart contract opportunities; bitcoin; Ethereum; Hyperledger fabric; Codra; Ethereum smart contracts; smart contract platforms; maturity models and CMMI maturity model;

   Sammanfattning : A smart contract is a recently emerging technology which enables agreement to be automatable by computers and enforceable by legal enforcement or tamper-proof execution of code. A majority of smart contracts are run on the blockchain which enables smart contract transactions without a central authority. LÄS MER

4. 3. Balancing Interoperability and Data Sensitivity: A Design Science approach to building a zero-knowledge API for Healthcare Data

   Master-uppsats, Uppsala universitet/Institutionen för informatik och media

   Författare :Suranga Ruwan Sampath Gunawardana; [2023]
   Nyckelord :Design Science Research Methodology DSRM ; Application Programming Interfaces API ; Interoperability; Platform; Health care Context;

   Sammanfattning : The aim of the study was to develop a platform to monitor and evaluate care homes using heterogeneous data sources for a French startup company. The study found that there was no current system to supervise healthcare resources in these facilities with live data. LÄS MER

5. 4. Emergency Communication for LoRaMesh using Blockchain and Distributed technologies

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Joakim Bjurehov; [2023]
   Nyckelord :Proof-of-concept; Emergency communication; Messaging application; Blockchain technologies; Distributed technologies;

   Sammanfattning : In today's society we need an emergency communication system to facilitate communication for when disaster strikes. Where the previous attempts only focused on the network communication and were missing a messaging capability between users. LÄS MER

7. 5. A Design Science Research Approach to Prove Meme Ownership: a Designed Artefact Utilising NFTs and Affordances

   Master-uppsats, Uppsala universitet/Informationssystem

   Författare :Zacharias Sundlöf; [2022]
   Nyckelord :design science research; blockchain; NFT; NFTs; meme; memes; digital ownership; affordance theory; affordance based design; design science;

   Sammanfattning : A rising problem exists regarding the ownership of memes. This research proposes a solution consisting of an IT artefact that solves this problem by utilising design science research in combination with affordance theory and non-fungible tokens (NFTs). LÄS MER
