  4. 3. 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
