2020, April | Collaboration project: A Blockchain application for tracking building materials

This year in April, I collaborated with TU Delft Blockchain Lab on a blockchain-based circular material tracking system for the social housing sector. To implement the circular economy in building processes, we need to know the history, content, quality and availability of the building components. Due to the fragmented nature of the construction supply chain and long lifespan of the buildings, this valuable information is lost in the course of buildings' lifetime.

As part of the Blockchain Engineering course, we challenged four master students with developing a blockchain-based asset management platform solution. The main functionality of the platform is tracing and recording every step of the building components, from manufacturing to demolition/reassembling processes, where all transactions between supply chain partners are verified and recorded, and building components are given digital identity.

Students designed a private and permissioned blockchain as stakeholders do not want to disclose sensitive information that might jeopardize their positions in the market. The blockchain system should be permissioned to allow transactions between authorized stakeholders. To find out the most suitable platform, students compared various open-source platforms that have implementation possibilities in supply-chain management. Eventually, they have chosen to use Hyperledger Fabric because of the private data features and the flexible access configuration it offers.

Details of their work can be found on GitHub. They have also shot a video explaining the tool they designed.

My take from this project is that material tracking needs good collaboration between supply chain partners. Implementing new technology is not an easy job for social housing providers. All stakeholders should be on the same page to co-create.
