Performance improvement of a blockchain simulator by reducing memory footprint

Abstract

Many works suggest new features and improvements to the Blockchain system. However, many of these features are evaluated after they are fully deployed to real usage because different protocol of the improved system requires reinventing the wheel for the same security evaluations. We need a standard Blockchain evaluation platform to make an easy comparison between various Blockchain systems and to make less developer's effort on testing various security attack cases. Large size Blockchain simulation on the evaluation platform requires massive memory usage. we suggest memory usage improvement methods with sharing Blockchain object on the simulation to reduce memory space required for duplicated Blockchain object. We evaluated the effectiveness of our improvement methods and showed that our improvement method can make 86% lower the memory usage increasing rate on the simulation scenario.
