The sophistication of education technology (edu-tech) from the perspective of the blockchain has not been well implemented, because so far the methods used in education are still centralized and tend to be any student data such as class schedules and student profiles can be falsified. So an edu-tech research was made that applied the blockchain to facilitate learning related to the industrial revolution 4.0 and was able to optimize the delivery of information that is currently still one-way. Although there are a number of benefits that have been felt about edu-tech, digital disruptions remain, many challenges related to information security and privacy. The presence of the blockchain in security work integrated with a smartphone will be able to optimize the existing security system, authentication, and information that has been distributed in relation to student profiles, which can be assured of their originality.

In order to create a chronological singlesource-of-truth for the data, a blockchain is a database that stores encrypted chunks of data before chaining them together. Instead of being copied or moved, digital assets are distributed, resulting in an immutable record of the asset. Due to the asset's decentralised nature, the public has complete real-time access and transparency. The public ledger and built-in security features of blockchain make it a top solution for practically every industry. Thus, in this paper we try to implement blockchain system to select an IDE Subject (INTER-DEPARTMENT ELECTIVE) which makes sure that the data isn't tampered through external source and the information is stored securely and is transparent to the college authorities and students.
