Ponudniki identitet z uporabo pametnih pogodb

ŠERAK, ROK (author), Šajn, Luka (mentor)

Anonimna narava verig blokov lahko predstavlja problem pri interakciji uporabnikov v decentraliziranih aplikacijah. Običajno želijo uporabniki vedeti, kdo je na drugem koncu interakcije. V večini obstoječih aplikacij je ta problem rešen s ponudniki identitet, vendar so te identitete pogosto vezane na uporabniški račun, česar se ne da enostavno povezati z računom na verigi blokov. Veriga blokov Ethereum ponuja podporo za pametne pogodbe, znotraj katerih lahko podatke hranimo, beremo, urejamo ali pa brišemo. V okviru diplomske naloge smo se zato odločili implementirati svojega ponudnika identitet z uporabo pametnih pogodb, kjer bi lahko uporabniki naložili identiteto za svoj račun Ethereum. Poleg tega smo dodali še spletni uporabniški vmesnik za interakcijo s ponudnikom identitet, s katerim je možen ogled in urejanje identitet posameznika.

• Title: Identity providers backed by smart contract

Abstract

The anonymous nature of blockchains can pose a problem for user interaction in decentralized applications. Typically, users want to know who is on the other end of the interaction. In most existing applications, this problem is solved with identity providers. But these identities are usually tied to some user account, which cannot be easily linked to an account on the blockchain. The Ethereum blockchain offers support for smart contracts within which data can be stored, read, edited, or deleted. So, we decided to implement our identity provider using smart contracts where users could upload an identity for their Ethereum account. Additionally, we have added a user interface for interacting with the identity provider, which allows viewing and editing individual identities.
