  1. 1. Assessing blockchain technology for Transport Data Logger

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

    Författare :Björn Johansson; [2018]
    Nyckelord :blockchain; transport data logger; hyperledger; hyperledger fabric; byzantine fault tolerance; bft; supply chain; transport chain; permissioned; permissionless; documental truth; historical truth; immutability; security; log data; Technology and Engineering;

    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.

  4. 4. Implications and Impact of Blockchain Transaction Pruning

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emanuel Palm; [2017]
    Nyckelord :Blockchain; blockchains; hyperledger; fabric; hyperledger fabric; private blockchain; permissioned blockchain; pruning; cryptography; computer science; disk; disk usage; memory; efficiency; pruning predicate function;

    Sammanfattning : This thesis presents an extension to Hyperledger Fabric, a private blockchain system, allowing historic transactions to be pruned without peer coordination. The feature is facilitated via pruning predicate functions, provided along any smart contracts a given system is desired to host. LÄS MER

  5. 5. Aiming for Supply Chain Transparency: Exploring the Potential of Blockchains

    Master-uppsats, Lunds universitet/Institutionen för service management och tjänstevetenskap

    Författare :Benedict Lützenburg; [2017]
    Nyckelord :blockchain; shared ledger; supply chain transparency; supply chain integrity; social sustainability; Technology and Engineering;

    Sammanfattning : Purpose: Supply chains lack transparency due to their complexity and fragmentation. Blockchain technology is increasingly expected to revolutionise businesses and promises to create trustworthy transparency. This study aimed to investigate the potentials of blockchain technology for supply chain transparency beyond the growing glorification. LÄS MER
