Análise de desempenho de simuladores blockchain: um estudo comparativo entre bitcoin-simulator, blocksim e simblock

Abstract

The adoption of blockchain technology has experienced a notable increase both in practical usage and in research within this field. Given the growing interest of organizations in this technology, it becomes imperative to have suitable tools to assess the feasibility of implementing blockchain networks with the aim of enhancing the services offered. In this context, a comprehensive experiment was conducted involving the construction and performance analysis of a blockchain network connecting all the capitals of Brazil. The experiment entailed the implementation of a blockchain network encompassing all the capitals of the country. To evaluate performance, three distinct blockchain network simulators were employed: BlockSim, SimBlock, and Bitcoin-Simulator. The primary objective was to conduct a comparative analysis of the performance of these simulators, aiming to determine which one would be more suitable for deployment in the context of Brazilian capitals. The analysis considered metrics such as simulation duration, CPU usage, memory usage, simulator configuration and flexibility, as well as the diversity of simulator data. Additionally, load tests were conducted to monitor the results generated by the simulators. The analysis addressed both the positive and negative aspects of each blockchain simulator, providing a comprehensive view of the capabilities and limitations of each tool. This study aims to provide crucial information for decision-making regarding the selection of the most appropriate simulator for implementing a blockchain network interconnecting Brazilian capitals, thereby contributing to optimizing services and maximizing the benefits of this innovative technology. At the end of the experiment, a suggestion will be made regarding which simulator achieved the best results based on the analyzed metrics.
