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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xinlin Zhu; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Privacy-Preserving Alternating Direction Method of Multipliers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ivar Källström; Lukas Gamard; [2023]
    Keywords : ;

    Abstract : As machine learning models affect our lives more strongly every day, developingmethods to train these models becomes paramount. In our paper, we focus on the problem ofminimizing a sum of functions, which lies at the heart of most - if not all - of these trainingmethods. READ MORE

  4. 3. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Felicia Törning; [2022]
    Keywords : Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

    Abstract : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose.

  5. 4. Comparison between consensus algorithms in an IIoT network : Analysis of Proof of Work, Proof of Stake and Proof of Authentication

    University essay from KTH/Hälsoinformatik och logistik

    Author : Baran Polat; Ilyas Göcmenoglu; [2022]
    Keywords : Proof of work; Proof of stake; IIoT; Proof of authentication; Blockchain; CloudRail; electricity consumption; time effectiveness; security; Proof of work; Proof of stake; IIoT; Proof of authentication; Blockkedja; CloudRail; elkonsumtion; tidseffektivitet; säkerhet;

    Abstract : The Industrial Internet of Things (IIoT) is growing day by day and is implemented in many industries. The centralized architecture of an IIoT system is composed of several devices that communicate with a special device only via one link, in an instance where this one link is attacked, major problems could occur for the whole system.

  6. 5. Implementing a Distributed Solution for the Message Broker LavinMQ

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Dahlén Christina; Weistrand Erica; [2022]
    Keywords : Consensus; Message Broker; Raft;

    Abstract : Today applications are often designed with a modular approach, dividing functionality into micro services rather than relying on a monolithic structure. This requires solutions for decoupled message exchange throughout the distributed system and can be achieved by implementing a message broker. READ MORE
