    Software aging is a phenomenon that plagues many long-running complex computer systems, which exhibit performance degradation or an increasing failure rate. Such a phenomenon may also be present in blockchain platforms. However, there are still no works focused on analyzing this phenomenon on these platforms. Thus, we adopted the Cardano blockchain to analyze software aging due to the presence of this technology in critical projects, its open-source nature and for being a sustainable solution. Considering the analysis of running a Cardano node on two computers with different configurations, we found evidence of software aging through memory degradation that was confirmed by the Mann-Kendall test. By analyzing the running processes, we confirmed that cardanonode (the main process of the platform) is the process possibly responsible for such degradation.
