Abstract
Zadatak završnog rada je upoznati se sa sustavom lanca blokova i njegovom sigurnosti. Detaljno je objašnjen princip rada i opisani su neki od mogućih napada na sustav. Kroz primjere napada, dan je detaljan pregled utjecaja sigurnosti lanca blokova na obavljanje transakcija te kako propusti unutar sustava mogu negativno utjecati na povjerenje i sigurnost korisnika. Tijekom analize napada na lanac blokova uočili smo da je ova tehnologija sigurna no postoje izazovi i ranjivosti s kojim se suočava. U cilju poboljšanja sigurnosti sustava, dane su mjere za jačanje sigurnosti lanca blokova. Uz sve izazove i sigurnosne rizike, lanac blokova i dalje pokazuje potencijal i primjenu u različitim sektorima. Primjeri korištenja lanca blokova u praksi svjedoče o inovativnosti i mogućnostima koje ova tehnologija pruža u stvaranju sigurnijeg, transparentnijeg i efikasnijeg poslovnog okruženja. Ova tehnologija ima velik potencijal za transformaciju različitih industrija. Međutim, kako bismo iskoristili sve prednosti koje nudi, ključno je kontinuirano ulaganje u sigurnost i razvoj odgovarajućih sigurnosnih mjera. Rezultat je cjelovit pregled sigurnosti sustava lanca blokova te prednosti i nedostaci korištenja istog.
Abstract (english)
The task of the final paper is to familiarize oneself with the blockchain system and its security. The working principle is explained in detail, and some possible attacks on the system are described. Through examples of attacks, a detailed overview of the impact of blockchain security on transaction execution is provided, as well as how vulnerabilities within the system can negatively affect user trust and security. During the analysis of blockchain attacks, it was observed that this technology is secure, but it faces challenges and vulnerabilities. In order to enhance the security of the system, measures to strengthen the security of the blockchain are presented. Despite all the challenges and security risks, blockchain continues to demostrate potential and application in various sectors. Examples of real-world blockchain usage attest to the innovation and possibilities that this technology offers in creating a more secure, transparent and efficient business environment. This technology has a great potential to transform different industries. However, in order to harness al the advantages it offers, it is crucial to continuously invest in security and develop appropriate security measures. The result is a comprehensive overview of the security of blockchain systems, along with the advantages and disadvantages of using them.
