  Blockchain technology provides a private, secure, transparent decentralized
exchange of data. Also, blockchain is not limited to a particular area, but it
has a wide range of applications and can be integrated into a variety of
Internet interactive systems. For example, the Internet of Things (IoT), supply
chain tracking, Electronic Health Records (EHR), digital forensics, identity
management, trustless payments, and other key business elements will all
benefit from its implementation. Next layer solutions such as Ethereum 2.0,
Polkadot, Cardano, and other Web 3.0 technologies provide developers
versatility. Moreover, these platforms utilize smart contracts which are
similar to standard, traditionalized software during development but offer key
utilities to end-users such as online wallets, secure data with transparent
rules. Blockchain is receiving a lot of attention in educational technology
(EduTech) as it aims to achieve a more transparent and multipurpose educational
system. In addition to smart contract technology which defines how data should
be registered, gathered and processed, blockchain can be used as an IoT
intermediary for mobile usage. Therefore, we implemented an educational
learning platform powered by blockchain technology to examine feasibility in
industry and academic environment. In essence, this is a web application which
is adapted to mobile platform and connected to blockchain for crucial data
exchanges. In this paper we want to emphasize the potential of blockchain
technology in multiple sectors as well as the need to really understand the
underlying principles which are allowing disruptability of traditional
centralized software solutions.
