Uporaba tehnologije veriženja blokov Cardano za upravljanje cepilnih potrdil

Trtnik, Vid (author), Lavbič, Dejan (mentor)

Med epidemijo virusa COVID-19 se je pojavila potreba po varnejših in zmogljivejših cepilnih sistemih, ki bi zagotavljali anonimnost uporabnikov. Pri tem problemu so se še posebej izkazale tehnologije veriženja blokov. V magistrski nalogi predstavljamo razvoj lastnega zdravstvenega sistema Cardano Vaccinator za upravljanje s cepilnimi potrdili. Sistem temelji na Cardanu, 3. generaciji tehnologij veriženja blokov, ki dosega odlične rezultate na področju učinkovitosti. Z upoštevanjem standardov W3C in vpeljavo gradnikov samoupravljive identitete, je uporabnikom zagotovljena visoka stopnja varnosti in zasebnosti. Sistem je integriran v naše prilagojeno konzorcijsko omrežje, ki temelji na verigi blokov Cardano. Shranjevanje datotek je realizirano tako s klasično centralizirano podatkovno bazo kot s porazdeljenim datotečnim sistemom IPFS. Cardano Vaccinator se v primerjavi z drugimi cepilnimi sistemi izkaže kot učinkovita alternativa, ki ne zahteva dodatnih stroškov pri opravljanju transakcij. Glede na analizo potencialnih obremenitev cepilnega sistema, dosega Cardano Vaccinator dobre rezultate in omogoča ažurno izdajanje cepilnih potrdil brez zakasnitev. Testi zmogljivosti kažejo, da bi bil sistem dovolj zmogljiv za uporabo v produkcijskem okolju.

• Title: Using the Cardano Blockchain Platform for Vaccination Certificate Management

Abstract

During the COVID-19 virus outbreak, a sudden need for a secure and anonymous vaccination system emerged. Blockchain technologies proved to be the best in tackling this problem. In this master's thesis, we present the development of our vaccination system Cardano Vaccinator. The system relies on Cardano, the third generation blockchain, which is more efficient than other technologies. The system provides high degrees of security and privacy by complying with the W3C standard and using a self-sovereign identity. Data storage is realized using a centralized database and distributed filesystems, like the IPFS. The system is integrated into our customized consortium network, based on the Cardano blockchain, which provides a good user experience. Cardano Vaccinator is an efficient alternative that does not present many costs. Regarding the analysis of the potential workload, it reaches good results and can issue vaccination certificates without delay. Benchmark tests show that the system is capable enough to be integrated into the production environment.
