Abstract

Kampanje javnog prikupljanja sredstava sve su češći način financiranja novih projekata, no dolaze uz otvorena pitanja oko pouzdanosti sudionika i sigurnosti prikupljenih sredstava. Postojanje okruženja u kojem bi ispravno i sigurno funkcioniranje prikupljanja i povrata sredstava bilo garantirano, pogodovalo bi povećanju popularnosti ovog načina financiranja, povećalo interes potencijalnih donatora i ohrabrilo pokretače novih projekata.
Tehnologija blok-lanca stvorila je okruženje za nastanak decentraliziranih kriptovaluta, omogućivši obavljanje transakcija bez uključivanja treće strane kao centralnog autoriteta kojemu se vjeruje. Platforma Ethereum, bazirana na tehnologiji blok-lanca, u takvom okruženju u kojem nema potrebe za vjerovanjem trećoj strani, omogućuje definiranje pametnih ugovora koji mogu sadržavati proizvoljnu logiku i pravila za vlasništvo, transakcije i ostalo.
Korištenjem pametnih ugovora platforme Ethereum, razvijeno je rješenje za decentralizirano prikupljanje sredstava, uz proširenja koja donatorima pružaju određenu kontrolu nad trošenjem prikupljenih sredstava, kao i mogućnost prekida projekta uz osiguran povratak preostalih sredstava.

Abstract (english)

Public fundraising campaigns, commonly called crowdfundings, are increasingly becoming a common way of funding new projects, but come with open questions regarding the trustworthiness of parties involved and the safety of raised funds. The existence of environment in which fundraising and refunding mechanisms are guaranteed to function correctly and safely, would benefit crowdfunding popularity, increase interest of potential contributors and encourage initiators of new projects.
Blockchain technology has created an environment for the emergence of decentralized cryptocurrencies, enabling the execution of transactions without the involvement of a trusted third party which acts as a central authority. In such a trustless environment, blockchain-based Ethereum platform enables defining smart contracts, which can contain arbitrary logic and rules for ownership, transactions, etc.
Using Ethereum smart contracts, decentralized fundraising extended with functionalities that provide contributors a certain degree of control over the spending of raised funds, as well as the possibility of aborting project with the guaranteed refunding of remaining funds, was developed.
