Abstract

This article presents a model built for deep digitalization in the construction industry and for making building information modeling achieve a greater level of transparency, verifiability and effectiveness for the benefit of all stakeholders. Thanks to blockchain and the self-sovereign identity paradigm, the model guarantees data integrity and transaction reliability, enabling the generation of more efficient and productive businesses. The model includes a decentralized application for notarization of the information flow in building information modeling processes; the application is implemented and tested on a local blockchain. The proposed model represents a so-called digital twin and is, hence, a huge system that manages all the information flow associated with a building throughout its life cycle, returning to individuals the control of their own data. In this model, all stakeholders operate based on so-called decentralized identifiers and DID documents, which store on-chain the fingerprints of the information flow in a common data environment.
