Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Hud, Jakub ; Perešíni, Martin (oponent) ; Homoliak, Ivan (vedoucí práce)
This thesis deals with testing the security and performance of PoS-based protocols. Comparison of ProPos, Algorand, Hedera, Ouroboros and Tezos is presented on theoretical level in terms of performance, attack vulnerabilities and attacks mitigation. This thesis includes a simulation framework for testing Algorand, ProPos and Hedera protocols. The simulation framework is created using Omnet++ 5.4.1. Focus of the simulation experiments is on the performance of the selected protocols. Based on the results of the experiments a few improvements are discussed.

Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Borčík, Filip ; Veselý, Vladimír (oponent) ; Homoliak, Ivan (vedoucí práce)
This work deals with performance and security testing of blockchain protocols based on the Proof-of-Stake (PoS) consensus model. It describes properties, problems, but also the use of blockchain systems. On theoretical levels, this thesis compares the properties and resistance to various attacks of numerous PoS protocols, specifically Algorand, Casper, Gasper, Snow White, Stellar and Decred. Additionally, this work implements a protocol simulator of Algorand, Casper FFG and Gasper. The simulator is built on top of the Bitcoin Simulator simulation tool, which is based on the NS-3 discrete network event simulator. Then, it compares the properties of the implemented protocols using discrete simulation.

Security and Performance Testbed for Simulation of Proof-of-Stake Protocols
Kotráš, Jan ; Hellebrandt, Lukáš (oponent) ; Malinka, Kamil (vedoucí práce)
This diploma thesis deals with blockchain technology with focusing on the consensus protocols, especially on proof-of-stake protocols type. This thesis describes blockchain technology followed by description of consensus in this technology. First part precisely describes a comparison of specific proof-of-stake protocols based on the theoretical knowledge. Second part of thesis focuses on the design and the implementation of a testbed. The testbed is used for comparison of proof-of-stake protocols practically. In the last section of thesis, we discuss our observed properties of proof-of-stake protocols and on this basement we indicate some next ways of evolution and improvement in the consensus and proof-of-stake protocols.
