  1. 1. Fair Voting System for Permissionless Decentralized Autonomous Organizations

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Erik Hellström; [2022]
    Nyckelord :blockchain; dao; crypto; cryptocurrency; p2p;

    Sammanfattning : The increasingly adapted technology called blockchain can be viewed as a distributed append-only time-stamped data structure which is made possible by a distributed peer-to-peer network. The network uses cryptography and different consensus mechanisms to ensure immutability, security, transparency, and speed in a decentralized fashion. LÄS MER

  3. 2. Assessing blockchain technology for Transport Data Logger

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Sammanfattning : A proof of concept permissioned blockchain system that holds data from the Transport Data Logger, TDL, was developed. Transport chain actors who hand off TDL-equipped goods between one another use the TDL app to upload a digital handoff containing their identities and log data from and signed by the TDL to a Hyperledger Fabric blockchain network.

    Nyckelord :;

    Sammanfattning : Electronic Health Records (EHRs) are both crucial and sensitive as they contain essential information and are frequently shared among different parties including hospitals, pharmacies or private clinics. This information must remain correct, up to date, private, and accessible only to the authorized people. LÄS MER

  5. 4. Trust and verifiable computation for smart contracts in permissionless blockchains

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Dominik Harz; [2017]
    Nyckelord :blockchain; smart contract; trust; multi-agent system; verifiable computation; blockchain; smart contract; trust; multi-agent system; verifiable computation;

    Sammanfattning : Blockchains address trust through cryptography and consensus. Bitcoin is the first digital currency without trusted agents. Ethereum extends this technology by enabling agents on a blockchain, via smart contracts. However, a systemic trust model for smart contracts in blockchains is missing. LÄS MER
