EKONOMSKA PERSPEKTIVA KRIPTOVALUTA I BLOCKCHAIN TEHNOLOGIJE : Završni rad

Kroz razvoj čovječanstva novac se pojavljivao u različitim oblicima, točnije nekad davno novac nije ni postojao nego su ljudi koristili različite predmete i proizvode koji su imali vrijednost na temelju koje se moglo trgovati. Nakon principa trampe došlo je zlatno doba gdje je novac zamjenjivalo zlato. Nakon perioda zlatnog standarda uslijedio je period tiskanja novca koji je prisutan i u sadašnjici no možda ne i u budućnosti. Pojavom digitalnog novca smanjuje se fizičko tiskanje novca jer je sada moguće trgovati novim načinom. Razvijanjem tehnologije te pojavom modernog doba korištenje kartica kao sredstvo plaćanja postalo je svakodnevnica. Problem se pojavio u tome što je digitalni novac pod vodstvom banke koja ima centralizirani sustav, a prisutna je i kontrola države. Zbog centraliziranog sustava i kontrole države nad novcem nastale su kriptovalute. Predmet ovog rada predstavlja mogućnost upotrebe kriptovaluta i ekonomskih učinaka istih na primjeru Bitcoina, a cilj je rada je utvrditi prikazati uporabu kriptovaluta, sigurnost takvih transakcija, oporezivanje i mogućnosti daljnjeg korištenja kriptovaluta. Lanac blokova odnosno eng. blockchain je baza podataka za spremanje podataka, informacija i dokumenata. Pomoću Blockchain tehnologije omogućena je distribucija digitalne informacije meĎu svim čvorovima koji sudjeluju u sustavu. U Bitcoin sustavu ne postoji središnja banka koja izdaje novac te čuva i obraĎuje transakcije, niti postoji jedinstveni vlasnik Bitcoin mreže. Ključna razlika Bitcoina u odnosu na centralizirane sustave proizlazi iz činjenice da svaki korisnik ima uvid u vlastite transakcije kao i transakcije ostalih sudionika.Through the development of humanity, money appeared in various forms, more precisely, back in time money had never existed, but people used different objects and products that had the value on which they could trade. After the tattered principle came the golden age where money replaced the gold. After the gold standard period, there was a period of money printing that is present in the present and perhaps not in the future. Digital cash is reduced by physical printing because it is now possible to trade in a new way. By developing technology and the emergence of modern times, using cards as a means of payment has become everyday. The problem has arisen in the fact that digital money is under the leadership of a bank that has a centralized system and there is also control of the state. Because of the centralized system and state control over money, cryptovalutes were created. The subject of this paper is the possibility of using cryptovalue and its economic effects on the Bitcoin example, and the aim of the paper is to establish the use of cryptovalue, the security of such transactions, the taxation and the possibility of further use of the cryptovalue. Block chain ie eng. blockchain is a database for storing data, information and documents. Blockchain technology enabled the distribution of digital information across all nodes participating in the system. There is no central bank in the bitcoin system that issues money and keeps and processes transactions, nor does it have a unique owner of the bitcoin network. The key difference between bitcoins and centralized systems derives from the fact that every user has an insight into their own transactions as well as the transactions of other participants
