Abstract
U ovom završnom radu najprije je prikazana teorijska analiza tehnologija na kojima počiva lanac blokova. Teorijski se obrađuju hashing, kriptografija javnog ključa, peer-to-peer mreže, Merkle stabla i neke od konsenzusnih metoda. Zatim je ukratko predstavljena najpopularnija javna decentralizirana platforma za stvaranje tzv. „pametnih ugovora“ – Ethereum i jezik na kojemu se ti ugovori pišu – Solidity. Zbog činjenice da je lanac blokova nepromjenjiv i troška transakcija na Eteheurum-ovom... More Mainnet-u za testno izvođenje napisanih programa preporučuje se korištenje nekog od dostupnih test-neta koji su predstavljeni ovdje. U teoriji, ne postoji granica veličinu bloka u Ethereum-u, ali tehnologija lanca blokova nije namijenjena za pohranu većih datoteka jer je to jako skupo. Međutim, blockchain se može koristiti za pohranu hasheva podataka koji se nalaze negdje drugdje – u našem slučaju to je IPFS. Korištenjem IPFS-a možemo osigurati dostupnost podataka bez visokog troška što je demonstrirano u ovom završnom radu. Sinergijom ovih dvaju tehnologija i alata koji njima barataju osigurano je relativno jednostavno i jeftino rješenje za verifikaciju diploma koje se kasnije može nadograditi. Less
Abstract (english)
In this paper firstly we introduced and theoretically analyzed what forms a basis for blockchain technology. We elaborated on hashing, public-key cryptography, peer-to-peer networks, Merkle trees and some of the consensus methods. Subsequently, the most popular decentralized platform for „smart contracts“ – Ethereum and the language in which they are written is introduced. Because of the fact that blockchains are immutable and the cost of transactions on Ethereum's Mainnet it is ... More recommended to use one of the testnets who are also introduced. In theory, there is no limit for a block size in Ethereum, but blockchain technology as it is is not meant to serve as a storage place for large files because that would be very expensive. However, blockchain can be used to store hashes of data that is stored somewhere else – in our case that is IPFS. By using IPFS we can ensure the availability of data without high costs which is demonstrated in this paper. A synergy of these two technologies and tools that work with them we made a relatively simple and cheap solution for verification of diplomas that can later be built upon. Less
