PriBB: A Benchmark Proposal to Analyze Blockchain Applications Performance

摘要

Blockchain is an emerging technology that has gained a lot of visibility in recent years due to its characteristics of transparency and immutability. Many studies have been carried out in order to use this technology in the financial industry, but there are still issues regarding scalability that need to be resolved before the technology can be used. In the literature there are works that perform Blockchain performance analysis of the private model, making comparisons between different platforms. However, no work was found regarding the analysis of the impact that changing parameters has on the performance of private model Blockchain applications. In this context, this article introduces PriBB that contributes to the literature regarding the proposal of a benchmark to evaluate the performance of private model Blockchain applications. In particular, it focuses on the impact that the parameters of block size and interval between blocks have on the performance of applications, since no equivalent work has been found in the literature. The PriBB was evaluated in a real data center environment and aims to assist in the optimization of parameterization of Blockchain applications of the private model. The results are promising and demonstrate that a given parameter can impact more than 100 times the performance in running Blockchain applications.
