Identifikacija komercijalne blockchain tehnologije te izazovi i opasnosti primjene kroz konkretne primjere

Abstract

Blockchain is a revolutionary technology with great potential for application in many branches of industry and integration into people’s daily lives as a technology of reliable data exchange through the Internet of Everything (IoE). The development of blockchain technology and cryptocurrency are closely related and have a common source in the Genesis block of the first fully functional blockchain, best known globally through the digital cryptocurrency Bitcoin. But even though blockchain technology has been commercially available for more than ten years, the average public still superficially and insufficiently distinguishes the terms blockchain from the name of the most famous cryptocurrency. The true value and benefit of blockchain technology is visible through observing the process of digital trust. In the way in which classic business transactions or contracts are initiated, there is no universal trust of all parties involved in the transaction. During classic transactions, that’s why for decades we put institutions accredited by law at the center of such transactions and agreements. Until the advent of blockchain technology (which was also created due to the impact of the great economic crisis of 2008, caused by the dishonesty and illegal acts of the world’s major banks, then ruling politicians and real estate dealers as the direct causes of the crisis), real technological solutions to the problem of mistrust did not actually exist. This article analyzes the commercial application and use cases of blockchain technology, and identifies the impact, challenges and dangers of blockchain technology. The article describes the specifics of blockchain technology, digital cryptocurrencies, the current commercial application of blockchain technology and recognizes existing and possible future problems of blockchain development through technological transformation and implementation in IoT and IoE.
