The advent of Web3, Construction 4.0, and the transition to BIM Level 3 has ushered in a wave of innovative technologies that call for a fresh approach to establishing secure connections and safeguarding sensitive information. This shift demands a departure from traditional paper-based identity methods to embrace digital alternatives. In this context, self-sovereign identity (SSI) emerges as a pivotal solution. SSI empowers individuals and entities within the construction industry to maintain full control over their digital identities, guaranteeing privacy, security, and seamless authentication across diverse platforms and systems. Through the adoption of SSI, the construction industry embarks on a transformative journey, empowering its stakeholders to confidently navigate the intricate terrain of contemporary construction processes and technologies.This study advocates for the creation of a self-sovereign digital wallet tailored specifically for the construction sector, harnessing the capabilities of Decentralized Identifiers and Verifiable Credentials. This digital wallet serves as a highly secure repository for all building-related data, ensuring both the integrity and accessibility of this valuable information. Our system proposal places particular emphasis on two key roles within this ecosystem: Contractors and Construction Companies. Each verifiable credential is intricately linked to a unique DID, securely stored in an on-chain registry.

Abstract

Z uveljavljanjem Web3, Gradbeništva 4.0 in s prehodom na BIM raven 3 prihaja val inovativnih tehnologij, ki zahtevajo svež pristop k vzpostavljanju varnih povezav in varovanju občutljivih informacij. Ta premik zahteva opuščanje tradicionalnih identitet na papirju in prehod k digitalnim alternativam. V tem kontekstu se pojavi samoupravna identiteta (SSI) kot ključna rešitev. SSI posameznikom in subjektom v gradbeni industriji omogoča popoln nadzor nad njihovimi digitalnimi identitetami, zagotavljajoč zasebnost, varnost in brezhibno avtentikacijo na različnih platformah in sistemih. S prehodom na SSI se gradben industrija podaja na pot preobrazbe, ki pooblašča deležnike, da samozavestno krmarijo po zapletenem terenu sodobnih gradbenih procesov in tehnologij. Študija zagovarja uvedbo samoupravne denarnice, prilagojene posebej za gradbeni sektor, ki izkorišča zmožnosti decentraliziranih identifikatorjev in preverljivih poverilnic. Ta digitalna denarnica deluje kot visoko varno skladišče za vse podatke, povezane z gradnjo, zagotavljajoč tako integriteto kot dostopnost teh dragocenih informacij. Naš predlog sistema še posebej poudarja dve ključni vlogi v tem ekosistemu: izvajalce in gradbena podjetja. Vsaka preverljiva poverilnica je zapleteno povezana s svojim edinstvenim decentraliziranim identifikatorjem (DID), ki je varno shranjen v register na verigi.
