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. HL-DRIP: A Blockchain-based Remote Drone ID Protocol registry management : Evaluation of a Hyperledger Fabric-based solution to manage DRIP registries

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Juan Basaez Serey; [2023]
   Nyckelord :DRIP; Drone Remote ID; Hyperledger-Fabric; IPFS;

   Sammanfattning : On January 15, 2021, the Federal Aviation Administration published the Unmanned Aircraft System Remote Identification rule with the intention of improving airspace security regarding the use of Unmanned Aircraft. According to the rule, UAs in flight must provide the public with information such as their identification, location, and altitude. LÄS MER

5. 4. Practical Analysis of the Giskard Consensus Protoco

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Leon Sandner; [2023]
   Nyckelord :Distributed Ledger; Blockchain; Consensus Protocol; Giskard; Hyperledger Sawtooth; Distribuerade Huvudbok; Blockchain; Konsensus; Giskard; Hyperledger Sawtooth;

   Sammanfattning : Consensus protocols are the core of modern blockchain systems, such as the Bitcoin, Ethereum, and Algorand networks. Thanks to these protocols, participants in a blockchain network can reach consensus on which blocks to add to a blockchain, to have a consistent chain of blocks in the whole network. LÄS MER

7. 5. Decentralized Validation of Reproducible Builds : A protocol for collaborative and decentralized validation of package reproducibility

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Johan Moritz; [2023]
   Nyckelord :Blockchain; Reproducible builds; Collaborative intelligence; Model checking; Hyperledger Fabric; TLA ; Blockkedjor; Reproducerbara byggen; Kollaborativ intelligens; Modeltestning; Hyperledger Fabric; TLA ;

   Sammanfattning : As the threat of supply-chain attacks grows, the need for techniques to protect software integrity likewise increases. The concept of reproducible builds is one such protection. LÄS MER
