Abstract
Blockchain predstavlja distribuiranu strukturu podataka odnosno listu digitalnih informacija podijeljenu između svih čvorova koji sudjeluju u sustavu. Blockchain nema potrebe za središnjim autoritetom već je sustav u potpunosti decentraliziran. Postizanje konsenzusa je najvažnija stavka sigurnosti blockchaina jer stavke koje ulaze u blockchain moraju biti jednoglasne, nepromjenjive i kriptografski zaštićene. Razlikujemo više algoritama za postizanje konsenzusa od kojih su najznačajniji proof-of-work i proof-of-stake. Cijela priča oko blockchain tehnologije postaje zanimljiva kada se pojavila prva kriptovaluta bitcoin. U početku vrijednost bitcoina je beznačajna, no kasnije postiže veću vrijednost i samim time postaje interesantna mnogima. Nakon bitcoina nastaju mnoge druge kriptovalute koje jos uvijek nisu postigle vrijednost i slavu bitcoina. Sve kritovalute su ponuđene na Initial Coin Offeringu, što predstavlja ponuđenu kriptovalutu i projekt u koji se može ulagati. naravno da svaka kriptovaluta neće biti značajnog rasta pa osoba koja namjerava ulagati mora dobro proučiti projekt. Primjena blockchaina trenutno najznačajnija je za financijski sektor. u budućnosti će se razvijati na sve više sektora. 2015. godine Vitalik Buterin kreirao je Ethereum. Ethereum blockchain mreža je fokusirana na pokretanje programskog koda bilo koje decentralizirane aplikacije. Prije je bilo potrebno napraviti cijelu blockchain mrežu za svaku pojedinu aplikaciju, Ethereum je omogućio da se taj korak izbjegne i bilo koja aplikacija može koristiti njegovu mrežu. Razvojem Ethereuma razvija se i pametni ugovor. Kada se pametni ugovor izvršava na blockchain mreži on postaje računalni program koji se samostalno izvršava kada su određeni preduvjeti zadovoljeni. Naknadnih promjena pametnog ugovora nema, kao ni malverzacija ili uplitanja treće strane. Kada govorimo o vrijednosti kriptovaluta, do njih se može doći na različite načine. Jedan od načina je rudarenje. Da bi se neka osoba uključila u rudarenje mora ulagati u računalnu opremu koja je zbog kriptovaluta u zadnjih dvije godine jako skupa. Ljepota ove tehnologije je sama primjena u svim aspektima poslovanja.
Abstract (english)
Blockchain represents a distributed data structure or a list of digital information shared between all the nodes participating in the system. Blockchain is completely decentralized. Consensus is the most important blockchain security item because items that enter blockchain must be unanimous, invariable, and cryptographically protected. We differentiate more algorithms to reach consensus, the most significant proof-of-work and proof-of-stake. The whole story about blockchain technology becomes interesting when the first cryptovalue bitcoin appeared. After the Bitcoin, many other crypt valutes are created that have not yet achieved the value and fame of bitcoins. All crypto currencies are offered on the Initial Coin Offer, which is the offered cryptourcing and the project that can be invested. Of course, any cryptovalue will not have a significant growth and the person who intends to invest must carefully study the project. The application of blockchain is currently the most significant for the financial sector. in the future it will develop to more and more sectors. In 2015, Vitalik Buterin was created by Ethereum. The Ethereum blockchain network is focused on running the program code of any decentralized application. With the arrival of Ethereum, smart contracts were developed. When a smart contract runs on the blockchain network it becomes a computer program that runs independently when certain prerequisites are met. There are no subsequent changes in the smart contract, no malpractice or interference from a third party. When we talk about the value of the cryptovalue, they can come in different ways. One way is mining. In order for a person to engage in mining, he must invest in computer equipment that has been heavily expensive due to cryptovalues in the last two years. The beauty of this technology is its application in all aspects of business.
