Abstract
Na področju sodobnih financ in bančništva se je razvila močna koncentracija kapitala v peščici finančnih središč. Kot alternativa takšni centralizaciji so se pojavile umetne deregulirane ter popolnoma distribuirane kriptografske valute. Njihova zasnova deluje na principu peer-to-peer omrežja, v katerem se s kriptografskimi funkcijami skupinsko nadzoruje transakcije in ustvarjanje same valute, kar omogoča transparentnost in hkrati anonimnost ter varnost. Za potrebe diplomskega dela smo sestavili napravo, ki z izkoriščanjem velike količine ter hitrosti pomnilnika na grafičnih karticah s posebno programsko opremo potrjuje transakcije v omrežju in nam s tem ustvarja majhen delež valute za nagrado. Opisali bomo lastnosti različnih kriptovalut, razložili metode maksimizacije dobička ter opisali uporabljeno strojno opremo. Podrobno bomo predstavili algoritem potrjevanja transakcij in prikazali vpliv konfiguracijskih parametrov na končno hitrost preračunavanja ter za konec povzeli ugotovitve.

Title:Calculating the cryptographic currencies with the GPU
Abstract:
In the field of modern finance a concentration has developed in a handful of financial institutions. As an alternative to such centralization, deregulated and fully distributed synthetic currencies were introduced. They are designed as a peer-to-peer network, where through use of cryptographic functions, transactions and creation of the currency are controlled, which allows for full transparency along with anonymity and security. For purposes of this thesis we have assembled a device that uses large amounts of fast memory on video cards by running special software which confirms transactions in the network, gaining us a small proportion of the currency as a reward. We will describe characteristics of various cryptocurrencies, explain methods for maximizing profit and describe the hardware used. We will explain in detail the algorithm behind the validation of transactions, show the influence of configuration parameters on resulting hashing speed and finally draw conclusions accordingly.

Keywords:cryptographic currency, cryptographic functions, anonymity, transparency, distributed currency, deregulation, bitcoin, scrypt, computer science, diploma
