Electronic voting systems face many challenges, including authentication, privacy, data integrity, transparency and verifiability. However, the developed over 10 years ago blockchain technology provides an out-of-the-box solution for many of those challenges. Despite that, some issues are still to be solved, like remote authentication, anonymity and end-to-end verifiability. For this reason, research on new and better blockchain-based systems is still ongoing. The main goal of this study is to highlight the current trends in this research and its eventual shortcomings. This was accomplished by conducting a Systematic Literature Review (SLR) (Kitchenham and Charters, 2007), which resulted in selecting 35 publications. The performed SLR allowed to define trends in utilized blockchain technologies, intended scenarios, testing methods, main benefits and challenges faced by various systems and the most used cryptographic solutions.

电子投票系统面临许多挑战，包括身份验证，隐私，数据完整性，透明度和可验证性。但是，十多年前开发的区块链技术为许多挑战提供了开箱即用的解决方案。尽管如此，仍需要解决一些问题，例如远程身份验证，匿名性和端到端可验证性。因此，有关新的和更好的基于区块链的系统的研究仍在进行中。这项研究的主要目的是强调该研究的当前趋势及其最终的缺点。这是通过进行系统文献综述（SLR）（Kitchenham和Charters，2007年）完成的，最终选择了35种出版物。所执行的SLR可以定义所利用的区块链技术，预期方案，测试方法，
