Blockchain is a jointly distributed and decentralized ledger, in which nodes are aiming to record transaction history with very different networks. This technology is quite practical if used in the field of higher education to carry out digital certification, record keeping, etc. From several papers published on this, no single paper covering educational projects based on the blockchain can find it. So there are the latest opportunities for higher education trends. Projects in the field of higher education that are blockchain-based are aimed at solving problems that occur in educators today. On that basis, we conclude that there is a need for a systematic literature review. Therefore, based on the education project, this study will review the artistic gap between the two. This paper will focus on the protocol used in this project and explore several blockchain-based higher education projects that will be the aim of this paper. As well as analyzing the blockchain features currently in use today and the services that will be offered by existing educational projects, to improve the implementation of technology in the field of education by using the blockchain feature.

The application of Blockchain technology in the context of providing security for transactions in the digital era 4.0 to prevent manipulation of transaction recording reports by irresponsible parties. By using research methods 10 (ten) literature reviews and methods of formulating problems, designing research, collecting data, processing & presenting data, analysis & research reports are expected to solve security problems in transactions. At present security in transactions is still very minimal, therefore a blockchain technology is needed to secure transactions where data can still be manipulated. Specifically, there are 2 (two) benefits of this research that use blockchain technology, (1) transactions become safer in the presence of encryption codes, (2) transactions become more transparent with blockchain. This research implements the encryption code into the payment system using AI Coin, where payment is now cashless, to make it more secure and transparent in transactions.
