  1. 1. A decentralized Git version controlsystem : A proposed architecture and evaluation of decentralized Git using DAG-based distributed ledgers

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Christian Habib; Ilian Ayoub; [2022]
    Nyckelord :Blockchain; Distributed ledger technology; Git; Version control systems; Software Security; Web3; Misuse cases;

    Sammanfattning : This thesis proposes an implementation for a decentralized version of the Git version controlsystem. This is achieved using a simple distributed DAG ledger. The thesis analyzeshow the decentralization of Git affects security. Use and misuse cases are used to compareand evaluate conventional Git web services and a decentralized version of Git. LÄS MER
