The rapid development of blockchain technology has influenced several fields, including financial, healthcare, and supply chain systems. Recently, this technology has also been applied in education thanks to its unique features, including decentralization, trustworthiness, and security. Despite the bright side of blockchain, several concerns continue to undermine its adoption in education, such as legal, immutability, and scalability issues. Thus, a comprehensive survey about blockchain adoption in education deems necessary. This paper is a systematic literature review of blockchain applications in the education field. To do so, and after retrieving scientific publications on the topic, we classify the outcomes according to several categories. In this paper, we focus on two major themes: educational applications and benefits of blockchain integration. We combine the themes, then express and analyze the results as bubble charts. We analyze the proposed solutions in terms of the blockchain-based applications that have been developed for educational purposes and the benefits that the blockchain technology could bring to the education field. Finally, we describe some research gaps that need to be addressed and educational areas that could be explored for future research of blockchain adoption in education.

区块链技术的快速发展已经影响了多个领域，包括金融，医疗保健和供应链系统。最近，该技术由于其独特的功能（包括去中心化，可信赖性和安全性）也已在教育中得到应用。尽管区块链有光明的一面，但仍存在一些担忧，例如法律，不变性和可扩展性问题，破坏了其在教育中的采用。因此，有必要对教育中采用区块链进行全面调查。本文是教育领域区块链应用的系统文献综述。为此，在检索有关该主题的科学出版物之后，我们根据几个类别对结果进行分类。在本文中，我们关注两个主要主题：教育应用和区块链集成的好处。我们结合主题，然后以气泡图的形式表达和分析结果。我们根据为教育目的开发的基于区块链的应用程序分析了提出的解决方案，并分析了区块链技术可以为教育领域带来的好处。最后，我们描述了一些需要解决的研究空白以及教育领域，可以探索区块链在教育中采用的未来研究。
