Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

Artikel i vetenskaplig tidskrift, 2025

Blockchain technology is a digital decentralized data ledger recording transactions in anencrypted format. Its implementation can potentially hold significant advantages for thebuilt environment, particularly in manufacturing and building product usage aligned withBuilding Information Modeling (BIM). This paradigm shift toward decentralized transac-tions can foster security, reliability, and accountability. Hyperledger Fabric (HLF), anenterprise-grade distributed ledger, offers a modular, scalable, and confidential digitalframework. This article introduces HLF-based workflows to address inefficiencies in BIMand fastener product lifecycle management, such as fragmented data handling and limitedprocess automation. Leveraging chaincodes linked to BIM models, HLF simplifies,enhances transparency, and automates construction product lifecycle processes. Contractdata and execution details are managed through a blockchain stored in a common dataenvironment (CDE) and linked to chaincodes. The article presents the conceptualizationand implementation of automated workflows, emphasizing efficiency and transparency.While showcasing successful deployments, it also highlights areas for future improvementand development. The proposed framework represents a pioneering step toward a decen-tralized cooperative environment in the construction industry, aligning with the transfor-mative potential of blockchain technology.
