   Sammanfattning : Inom revisionsbranschen tenderar arbetsbelastningen att vara extra hög, framför allt under de två första kvartalen vilket bidrar till hög stress och långa arbetsdagar. I dagens samhälle spelar den teknologiska utvecklingen en stor roll. LÄS MER

7. 5. Consensus Algorithms in Blockchain : A survey to create decision trees for blockchain applications

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

   Författare :Xinlin Zhu; [2023]
   Nyckelord :Blockchain; Cryptocurrency; Consensus Algorithms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree; Blockchain; Kryptovaluta; Consensus Algoritms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree;

   Sammanfattning : Blockchain is a decentralized database that is distributed among a computer network. To enable a smooth decision making process without any authority, different blockchain applications use their own consensus algorithms. The problem is that for a new blockchain application, there is limited aid in deciding which algorithm it should implement. LÄS MER
