  Nowadays, huge amounts of data are generated every second, and a quantity of
that data can be defined as sensitive. Blockchain technology has private,
secure, transparent and decentralized exchange of data as native. It is
adaptable and can be used in a wide range of Internet-based interactive systems
in academic and industrial settings. The essential part of programmable

technologies are smart contracts. Smart contracts are programs executed on the
global blockchain, the code is public as well as all of the data managed within
the transactions, thus creating a system that is reliable and cannot be cheated
if designed properly. In this paper, in order to make the educational system
more transparent and versatile we will describe an educational learning
platform designed as a distributed system.
