Blockchain technology, due to its nature, does not allow transactions to be made free of charge. Therefore, a transfer cannot be made below a certain amount. There is a transfer fee, even if it is symbolic. IOTA has created a completely free system to make it possible to make even very small transfers.
Every user who wants to make an IOTA transfer confirms the last two transactions made before and the system continues to operate on its own.
IOTA was created to sell the data collected by smart objects that will become a part of our lives in the not too distant future. As IoT technology was developed, an open market idea emerged where the information collected from smart devices used in the workplace or at home would be sold. IOTA is a project developed to adapt this idea to the cryptocurrency world.
