Visokorazpoložljiva arhitektura za decentralizirano spremljanje tečajev kriptovalut

SOVDAT, BERNARD (author), Jurič, Matjaž Branko (mentor)

V diplomski nalogi bomo predstavili osnove delovanja decentralizirane platforme Ethereum, opisali različne mehanizme soglasja in jih primerjali. Raziskovali smo tudi oraklje, pri katerih smo ugotavljali razlike med centraliziranimi in decentraliziranimi oraklji, njihovo vlogo in pomen v svetu bločnih verig. V nadaljevanju se bomo posvetili decentraliziranem oraklju FTSO (Flare Time Series Oracle), kjer smo analizirali njegove ključne komponente, kako posredovalci podatkov posredujejo le-te, opisali različne pametne pogodbe, ki ga sestavljajo in kako deluje njihovo nagrajevanje. Na koncu bomo predstavili različne modele za napovedovanje cen, ki smo jih preizkusili ter primerjali njihovo uspešnost.

Abstract

In this thesis, we will present the basics of the decentralised Ethereum platform and describe and compare different consensus mechanisms. We will also focus on oracles, exploring the differences between centralised and decentralised oracles, their role and importance in the blockchain world. Next, we will focus on the decentralised Flare Time Series Oracle (FTSO), where we analyse its key components, how data providers submit data, describe the different smart contracts that it is composed of and how their rewards system works. Finally, we will present the price forecasting models we have tested and compare their performance.
